Re: [one-users] sunstone says : "OpenNebula is not running"
Hello, Could you paste the contents of oned.log then? It should be located under /var/log/one/ folder. Maybe we can find more information there about the problem. Also, did you check if ONE_AUTH environment variable is properly set (pointing to the one_auth file, usually located under $HOME/.one/one_auth, and containing a single unencrypted line "oneadmin:password", where $HOME is the home folder of oneadmin user)? Cheers, Lehel. --- On Tue, 5/1/12, Guigui 6675636b206f wrote: From: Guigui 6675636b206f Subject: RE: [one-users] sunstone says : "OpenNebula is not running" To: lehel.b...@yahoo.com Date: Tuesday, May 1, 2012, 10:43 AM Hello Lehel, No, unfortunatly, that's the the problem.

Re: [one-users] KVM drivers fail to load? [MAD did not answer INIT command]
Hi, I've found out that the reason for my problems was that libvirtd was continuously crashing at start-up on my OpenNebula Front-End. Since I didn't manage to repair it so far, for the time being, I disabled it completely, and this seemed to make the error disappear, that is, my KVM drivers are loaded successfully ever since. However, I got a question here, which might be naive, but I got really curious now: shouldn't the hypervisor, virtualization drivers, libvirt settings and all the related stuff be affecting OpenNebula only in case of the hosts? How (and why) does the fact that libvirt is crashing on my front-end affect the ONE system? Thanks, Lehel. --- On Thu, 4/19/12, biro lehel wrote: From: biro lehel Subject: Re: [one-users] KVM drivers fail to load? [MAD did not answer INIT command] To: "Ruben S.

Re: [one-users] Trouble setting VM's hostname
Hello Pedro,
Indeed, my problem was that the init.sh script has not been at all executed.
I've spent the last day trying to trace down the problem, which was rather
weird, since the exact same configuration (as presented in the example in the
documentation you provided, too) worked on another one of my images, and the
init.sh script was properly called. I didn't manage to find the cause, however,
I did manage to solve my problem with a simple workaround applicable in my
case, which was to set the following script as an init script on my respective
image:
# OpenNebula Network Contextualization
MAC=`ifconfig eth0|grep HWaddr|awk '{print $5}'`
for i in `echo $MAC|cut -d: -f3-|tr : ' '`; do
[ -n "$IP" ] && IP=$IP.
let c=0x$i
IP=${IP}$c
done
GATEWAY=`echo $IP|cut -d. -f1-3`.1
ifconfig eth0 $IP netmask 255.255.0.0
route add default gw $GATEWAY
hostname "SLAVE${IP:9:12}"
This last line sets the hostname at the first boot to
, and that was just
what I needed.
Thank you for taking the time to answer.
Cheers,
Lehel.

Hello,
Are you sure that your init script is running at VM startup?
If so, be sure to 'source' the file context.sh that contains $HOSTNAME
definition, before running your script.
If you are using hdc as your device where the contextualization image will be
available, you can use something like this at startup:
#!/bin/sh -e
mount -t iso9660 /dev/sdc /mnt
if [ -f /mnt/context.sh ]; then
. /mnt/init.sh
fi
umount /mnt
exit 0
Take a look at last section (EXAMPLE) here:
http://opennebula.org/documentation:archives:rel3.2:cong
For opensuse init script, read this:
http://www.novell.com/coolsolutions/feature/15380.html
Regars,
Pedro Vitti

I'm using
openSUSE 11.4 and OpenNebula 3.2.0.
What are the other ways to try to set the hostname in my VM's? Since more VM's
will use the same image, I cannot simply set it in my image. Is anything need
to be done regarding the hostname in the respective image?
Thanks,

Re: [one-users] VM forced deletion? [VM hanging in CLEANUP state]
Okay, so far, for my hung VM, I have set the "default" values for the deleted VM's in the vm_pool table of one.db (more precisely, I have set: last_poll=0, state=6, lcm_state=0), and also, in the leases table, I have freed the respective IP address (=0, =-1). However, I'm looking for a confirmation if this is okay, or it can cause inconsistencies. Is anything else need to be done?

Re: [one-users] SaaS with opennebula cloud
I'll just put this on the list, it seems like Daniel is busy, but maybe someone else can help me with an answer. Thank you in anticipation, Lehel. Daniel, two more things.. When creating a new occi template, can I use as IMAGE_ID an ID of an existing peristent image (of course one that is not currently USED)? At the moment I have some persistent images, from which I configured and set-up VM's with some specific software (I'm working on building a kind of "platform" above the "infrastructure"), and I intend these VM's to be used by end-users. In my original templates (that are using the persistent images), besides the image disk definition, I had some further disks defined (type FS and SWAP). Would these disks be available if I pass only the persistent image ID in my new_occi_template.erb? I mean, would I get "the very same VM back"? Also, I read that Self Service currently supports only ranged networks. Does this mean that there is no way to set for a specific VM a specific IP address?

OpenNebula Self-Service is a simplified GUI aimed to end-users, offering a simplified access to shared infrastructure for non-IT end users. The administrator will configure a set of instance_types that the end-user will be able to select without taking care of the VM configuration. The user can login to this portal and interact with his resources. The VirtualNetworks and Images can be exposed in three different ways: 1. The administrator creates the VNETs and Images through the one* tools and distributes these resources in different instance_types. The end-user will just have to select the desired instance_type $ onevnet create occi_vnet ID: 2 $ oneimage create occi_image ID:3 $ cat $ONE_LOCATION/etc/occi_templates/new_occi_template.erb CPU=1 MEMORY=1024 DISK=[IMAGE_ID=3] NIC=[NETWORK_ID=2] $ cat $ONE_LOCATION/etc/occi.conf [...] :instance_types: [...] :new_occi_template: :template: new_occi_template.erb :cpu: 1 :memory: 1024 2. The administrator creates the VNETs and Images through the one* tools and makes them available for the end-user. The end-user selects which instance_type he wants to use and what image and network throught the GUI interface. $ onevnet create occi_vnet ID: 2 $ oneimage create occi_image ID:3 $ cat $ONE_LOCATION/etc/occi_templates/new_occi_template.erb CPU=1 MEMORY=1024 $ cat $ONE_LOCATION/etc/occi.conf [...] :instance_types: [...] :new_occi_template: :template: new_occi_template.erb :cpu: 1 :memory: 1024 3. The end-user is allowed to create VNETs (you can also define a base template for this) and upload Images and can select them for a new instance through the GUI interface $ cat $ONE_LOCATION/etc/occi_templates/new_occi_template.erb CPU=1 MEMORY=1024 DISK=[IMAGE_ID=3] NIC=[NETWORK_ID=2] $ cat $ONE_LOCATION/etc/occi.conf [...] :instance_types: [...] :new_occi_template: :template: new_occi_template.erb :cpu: 1 :memory: 1024 If you want to enable VNC you have to add the following line to the templates: GRAPHICS = [ TYPE = "vnc", LISTEN = "0.0.0.0", PORT = "5"] Hope this helps Refs: * Self Service UI: http://www.opennebula.org/documentation:rel3.4:selfservice * Adding new VM types: http://www.opennebula.org/documentation:rel3.4:occicg#defining_compute_types * VNET base template: http://www.opennebula.org/documentation:rel3.4:occicg#configuring_occi_virtual_networks * Permissions: http://www.opennebula.org/documentation:rel3.4:manage_acl * Vm template: http://www.opennebula.org/documentation:rel3.4:template > > > Cheers, > Lehel. > > --- On Thu, 3/29/12, TARUN TANK <08bit...@nirmauni.ac.in> wrote: > > > From: TARUN TANK <08bit...@nirmauni.ac.in> > Subject: [one-users] SaaS with opennebula cloud > To: users@lists.opennebula.org > Date: Thursday, March 29, 2012, 12:46 PM > > > hi, we have developed the opennebula cloud with front end and 5 worker nodes > , we can successfully create the VM and can deploy them on the worker > nodes.Hence we are able to run the windows as well as linux on the dom U of > the worker nodes(using XEN) .

Hector, Indeed, the problem is that the wsproxy process remains hanging after some time. Killing it manually makes the error disappear, thank you very much for the hint.

Hello, I seem to have a noVNC-related issue. From time-to-time, I get a "Server disconnected" error, when accessing my VM's through VNC. I've noticed that it usually (only) happens when I was previously connected to that specific VM (for which the error occurs) through VNC for an extended period of time (but not more than 10-15 minutes), closed the connection, and then tried to reconnect (this is where I get the error). It never happened (so far) in situations other than this, if the VNC-connections are short-termed in time, I can close and reconnect to VM's through VNC as many times as I want. The only workaround I've found so far is rebooting both the front-end and the respective host, which, as you can imagine, is rather inconvenient to do each time this error occurs. sunstone.log contains the following about the error: Starting vnc proxy: /usr/share/one/noVNC/utils/wsproxy.py 35822 pcls:5946 /usr/lib/one/sunstone/models/SunstoneServer.rb:234: warning: Insecure world writable dir /usr/X11R6/bin in PATH, mode 040777 127.0.0.1 - - [31/Mar/2012 12:08:17] "POST /vm/46/startvnc HTTP/1.1" 200 30 0.1036 127.0.0.1 - - [31/Mar/2012 12:08:17] "GET /vendor/jQueryUI/images/ui-bg_glass_55_fbf9ee_1x400.png HTTP/1.1" 200 120 0.0116 Traceback (most recent call last): File "/usr/share/one/noVNC/utils/wsproxy.py", line 282, in server.start_server() File "/usr/share/one/noVNC/utils/websocket.py", line 794, in start_server lsock = self.socket(self.listen_host, self.listen_port) File "/usr/share/one/noVNC/utils/websocket.py", line 185, in socket sock.bind(addrs[0][4]) File "/usr/lib64/python2.7/socket.py", line 222, in meth return getattr(self._sock,name)(*args) socket.error: [Errno 98] Address already in use 127.0.0.1 - - [31/Mar/2012 12:08:32] "POST /vm/46/stopvnc HTTP/1.1" 200 - 0.0856 Since I'm not an expert in Python, I didn't want to dig myself into the above-named files so far.

Re: [one-users] Error when instantiating VM from persistent image
Hi Jhon, The qemu configuration was fine, and also the NFS is (or at least seems to be) working fine, the problem indeed was with the permission settings of the specific image file in the /images directory. It only had RW permissions for owner (oneadmin) and root, and forbidden for others. The problem is now solved, the VM's created from the persistent image are running, and I indeed checked their persistency after a graceful shutdown. Thank you very much for taking the time to answer, and for your detailed description. Have a great day, Cheers, Lehel. --- On Thu, 3/29/12, Jhon Masschelein wrote: From: Jhon Masschelein Subject: Re: [one-users] Error when instantiating VM from persistent image To: "biro lehel" , users@lists.opennebula.org Date: Thursday, March 29, 2012, 9:33 AM Hi, it looks like this is the problem: > Wed Mar 28 10:50:00 2012 [VMM][I]: error: internal error process > exited while connecting to monitor: qemu-kvm: -drive > file=/var/lib/one//25/images/disk.2,if=none,id=drive-ide0-0-0,format=raw: > could not open disk image /var/lib/one//25/images/disk.2: Permission > denied At this point it would appear that oneadmin has access to the disk image file /var/lib/one//25/images/disk.2, but qemu does not. The error is coming from qemu. As far as I know, the difference between a persistent image and a non persistent image is that, when it is not persistent, the image get copied by oneadmin and new permissions are set on the new file, but when you are using a persistent image, a symbolic link is created. With symbolic links, the permissions of the link are not important, the permissions on the original file are used. So, when you look at the file that is listed as the "SOURCE" of your image. (Should be something like /var/lib/one/images/c0dc71ebe6562d4e8c9e186b249bff13, what are the permissions and is qemu (on the execution node) able to read&write to it? Probably that is the problem and the next thing to look for is why his file is not readable by qemu. The file was created by oneadmin at the time the onimage command was run on the opennebula server to create the Image object. Now the qemu process on the execution node is trying, and failing, to access the file. Do you have special directory permissions on the image directory? Is it an NFS mount that is doing "strange" things? A couple of other things that could be related: - did you set dynamic_ownership = 0 in the qemu.conf file onthe execution node? - did you change the user or group the qemu process is running as?

[one-users] Set the number of VM's instantiated - but not through Sunstone or CLI?
Hello, Is there any way to set the number of created VM's that would use a specific (same) image file? What I want to obtain is the following: I would have some kind of an "end-user" (the point is, NOT an OpenNebula-user), that would need to specific three parameters (let's say, through a config file): his needed CPU, his needed Memory, and the number of VM's he would like to have for this configuration. Then, I would have a previously pre-set and pre-filled OpenNebula template, which my system should complete with the CPU and Memory information. Finally, the number of the instantiated VM's (set by the user) should be communicated with OpenNebula - and this is what my question refers to. Is there a way to do this? Also, how can an end-user communicate with (that is, how can I "propagate" the information to) OpenNebula? Don't think of huge security issues here, I only have a small research/test environment, not a production one. I could even use oneadmin's credentials for him, I just don't know how to "externally" access OpenNebula, if possible. Thank you, and waiting for your answers, Lehel. ___ Users mailing list Users@lists.opennebula.org http://lists.opennebula.org/listinfo.cgi/users-opennebula.org

[one-users] GRID-like functionalities with OpenNebula as a base? [Hadoop, or other possible solutions]
---My first email didn't seem to reach the list (or it's just Yahoo playing with me...), ---so I copy it once again here. I hope it will work this time. Dear all, After having successfully set up a small-scale (but up-and-running) experimental Private Cloud (using OpenSUSE 12.1 64bit machines -also VM's-, KVM as hypervisor, and ONE 3.2.0), my next task is to find a way in which GRID-like services (see below) could be implemented inside an OpenNebula-based Cloud. Basically, and architecturally-speaking, I think I would need a PaaS layer above my existing IaaS layer. I am interested in the following tasks: * job distribution among a set of dynamically created (or, as a start, fixed) VM's, initiated by a master-VM * job execution on the worker-VM's and, more importantly, execution monitoring of these jobs by the master-VM * results gathering on the master-VM I have briefly looked though Hadoop, which uses MapReduce, but, having no experience with it, I am not sure whether if it is the best tool to use for such a use-case, and also, I don't know if it could be at all used in my environment. So, my fundamental question is the following: which is the best way to start on, a way that would lead to satisfying my above-mentioned 3 necessities? Is Hadoop perfectly compatible with OpenNebula, and could be used for such purposes, or are there other and more fitting solutions or tools to use? Basically, all I'm asking is, what is the most appropriate way for obtaining these basic GRID-computing functionalities on a Platform constructed above the Infrastructure? Any suggestions, thoughts, and hints are extremely welcome, since this is a rather important and urgent matter for me.

I am interested in the following tasks: * job distribution among a set of dynamically created (or, as a start, fixed) VM's, initiated by a master-VM * job execution on the worker-VM's and, more importantly, execution monitoring of these jobs by the master-VM * results gathering on the master-VM I have briefly looked though Hadoop, which uses MapReduce, but, having no experience with it, I am not sure whether if it is the best tool to use for such a use-case, and also, I don't know if it could be at all used in my environment. So, my fundamental question is the following: which is the best way to start on, a way that would lead to satisfying my above-mentioned 3 necessities? Is Hadoop perfectly compatible with OpenNebula, and could be used for such purposes, or are there other and more fitting solutions or tools to use? Basically, all I'm asking is, what is the most appropriate way for obtaining these basic GRID-computing functionalities on a Platform constructed above the Infrastructure? Any suggestions, thoughts, and hints are extremely welcome, since this is a rather important and urgent matter for me. Thank you, Lehel. ___ Users mailing list Users@lists.opennebula.org http://lists.opennebula.org/listinfo.cgi/users-opennebula.org
[one-users] [openSUSE 12.1 + OpenNebula 3.2.0 + KVM. Template to be used?]
Okay, I just bumped into Suse Studio right after sending my previous mail; I must have been a moron for not discovering it before. As I understood, it provides me with a raw image file (with .raw extension), so my only question related to this matter is: can this .raw file be used in the exact same manner as the .img file (in case of ttylinux, for example)? Also, my second question is still actual, and is even more important now, so I copy it from the previous mail (so that thread can be discarded): For anyone having experience with SUSE + ONE + KVM (I've seen that there are a few of you here): could you provide me with an example template for your configuration, that I could use as a starting point for my configuration? It would really be a great help. Aaand, as a last 'bonus' question: is VNC a proper graphical tool to access the VM's interfaces (like, the Remote Desktop functionality in Windows, for example), or just provides a CLI for the machines? Thank you very much, Lehel. ___ Users mailing list Users@lists.opennebula.org http://lists.opennebula.org/listinfo.cgi/users-opennebula.org
[one-users] [openSUSE + OpenNebula 3.2.0 + KVM. How to obtain an .img file?]
Hello everyone, Regarding my last issue here, the problem with the VNC connection initialization through Sunstone was indeed the presence of the line ['TIGHT_PNG', -260 ], in rfb.js. Uncommenting it solved the problem; thank you Carlo and Hector for you prompt feedbacks. So, at my current progress, I managed to create VM's from the provided ttylinux image without problems, VNC is also working, I could ssh and ping in all the possible directions, and, to gain some experience, I even fooled around a bit with some template attributes to see their effect. So, i guess that "so far, so good". Now, my next step would be to do the same thing with VM's created from an openSUSE image. In order to do this, I would need a raw openSUSE .img file (just like I had ttylinux.img), but, lacking any experience in the domain, I'm a little bit helpless regarding the exact way of obtaining such an .img file for my distribution. I have checked some online documentation, but none of it really helped. So, my question is, what is the correct and best way to obtain such a SUSE image, or are there any ways to get it from somewhere? Just for the record (as stated in the subject), I'm using KVM as hypervisor. Also, for anyone having experience with SUSE + ONE + KVM (I've seen that are a few of you here): could you provide me an example template for your configuration, that I could use a starting point for my configuration? It would really be a great help. Thank you very much, Lehel. ___ Users mailing list Users@lists.opennebula.org http://lists.opennebula.org/listinfo.cgi/users-opennebula.org
[one-users] noVNC problems AND question about VM images [OpenNebula 3.2.0 on openSUSE]
Hello again, First of all, thank you for all your feedback and help so far, it's been immense! Also, Hector, you were right in the previous email, the monitoring info is now fine, after I started the oneacctd daemon (I simply forgot to restart it after some continuous reboots, stupid me). That single error message with the earlier timestamp is still there, but it doesn't seem to bother, so I guess it is not crucial. My current issue is the following: I managed to create a VM using the ttylinux image provided by you, and following the documentation at [1]. Everything went fine, the VM reached its running state, and I managed to passwordlessly ssh into it. However, I wanted to try the noVNC functionality, since I would probably use (at least) a graphical console to my VM's in the future. I installed noVNC with install_novnc.sh (succeeded), added the necessary GRAPHICS section to ttylinux.one template: GRAPHICS=[ LISTEN=0.0.0.0, TYPE=vnc ] , and recreated the VM. As expected, the VNC icon turned active in Sunstone, however, clicking on it resulted in the following error message: WebSock error: Illegal basic compression received, ctl: 96 I'm not sure, but I guess I have to make some kind of VNC-related configurations on my host machine, but I didn't want to do anything drastic (and also, I have to leave the computers soon), until I ask for your opinions. The firewall on my host is disabled. Any suggestions about what shall I do? Also, and more importantly: my current set-up with the ttylinux VM went smoothly and without errors. However, in the future, I want to use VM's that use other images (preferably, a fresh openSUSE 12.1 -or 11.4- install image). And, it mind sound like a 'noob' question, but I'm not sure how exactly these image files are created, so that at the end I obtain something like an openSUSE_.img file. So, my question is, what should I do, in order to obtain the respective image file, that I would be able to use like the provided ttylinux.img file? Do I have to create it somehow, or are there other method to get/download it? I do have an installation DVD for both 11.4 and 12.1 versions, if it helps. Also, does the created VM need to have something specific installed / some specific configurations done BEFORE the VM deployment (I mean the way in which the image file is created), or any simple "fresh" (empty, basic) install image will do? Since my two main questions are unrelated, I would gladly accept any suggestions or opinions on any of them. Thank you, and have a great weekend, Lehel.

Re: [one-users] Monitoring issue right after host creation [No Monitoring Information | OpenNebula 3.2.0]
Hello, I managed to resolve the issues regarding the monitoring, by following the instructions at [1] (sections 7.1.1.1. and 7.1.1.2), and at [2] (the section regarding PolicyKit). Now, 'onehost show 6' results in the following (see below). As you can see, although the monitoring info returned the correct result, it still contains an error message, which is stuck there from an earlier time (the timestamp of the error message is not the actual time of the monitoring, it shows the timestamp of an earlier unsuccessful monitoring try). The oned.log contains no errors. Also, I suppose because of this error message (which also appears at the bottom of the "Host Template" tab, with my current Host selected in Sunstone), the "Monitoring Information" tab shows "There is no monitoring information for host 6" both at CPU and Memory info. Any idea how to work this around? Also, my initial socket problem (I copy the following from messages.log): Mar 9 10:10:57 pcls libvirtd[5603]: Starting libvirtd WARNING: no socket to connect to Mar 9 10:10:57 pcls libvirtd[5603]: ..done , still persist. This message also appears when trying to run anything related to 'virsh' on my host,, for ex: > virsh -c qemu:///system list WARNING: no socket to connect to Id Name State -- , and also, it appears when running run_probes on my host (although after the warning, it returns the correct information). It is kind of bothering me, and I could find the reason of it so far. It is also making it hard to trace the fact that besides this warning message, no errors messages are issued nowhere, and I couldn't trace it in the logs neither, so far. Any ideas what causes this socket warning? Please help.

Firing the respective command on the host ( /var/tmp/one/im/run_probes kvm 4 pcls ) also results in no output and no errors (it simply puts a space on a new line in the CLI). I don't think that this is the expected behavior and I think that there is a problem somewhere. What am I missing? Any suggestions?

Re: [one-users] Can't log onto Sunstone [OpenNebula 3.2.0, OpenSUSE 11.4]
Indeed, the root of all problems was that /var/lib/one/remotes/auth/server_cipher/authenticate had no execution permissions. I managed to log on now into Sunstone without problems. Thank you Daniel. But since this is a file created by OpenNebula, shouldn't this behavior be assured by default? Or at least mentioned somewhere in the documentation? Or is it an issue with my system? (it's the first time I extensively use openSUSE or any other Linux distribution) This last question leads to a more important one: if I had this (seemingly strange) issue, is it possible that I will have problems caused by similar reasons in the future? What should I check?

It's the first time I see such a username; serveradmin is a user used by the servers (EC2, OCCI, Sunstone...) to authenticate on behalf of other users. You should not authenticate with this user or change its password, it is a user used by the system. You can find the credentials for this user in the following files for each server $ ls $ONE_LOCATION/var/.one/ ec2_auth occi_auth sunstone_auth The content of these files should be: serveradmin:passinplain So if you changed the serveradmin password using the CLI, oneuser passwd serveradmin newpassword you have to update those files as follows: $ cat sunstone_auth serveradmin:newpassword > > * Shouldn't I be logging in with "oneadmin" user, and it's system password > (the password with which I normally log into my system)? You have to log in with oneadmin or a different cloud user, but you never have to use the serveradmin user.

Hello Jaime, Thank you very much for your answer. I performed your suggestions, and changed back the DB backend to SQLite (also, checked the executing permissions you have mentioned). However, my initial problem still exists. I can't log on with oneadmin's user and password to the main Sunstone interface (I get the "OpenNebula is not running" error each time, written in red above the log-in box, although oned daemon is started). I checked one.db , to see what password is set for oneadmin, but I couldn't find any password field. Any suggestions what should I do?

[one-users] Version 3.2.0 + MySQL problems
Hello,
I have an issue about using OpenNebula with MySQL. I have downloaded and
installed version 3.2.0 using YaST on an openSUSE machine. The root of all my
problems was when trying to log in the main Sunstone window, (with oneadmin
user and password), i got the following error: "OpenNebula is not running". So
I checked if the daemon was running (it was), and then I digged deeper into it,
and found out that is probably a database issue. I have followed the
instructions at [1], although it is probably a problem that I've only made the
necessary changes in oned.conf AFTER running first-time the oned daemon. Now,
at my one.db file (I wanted to check what password is set for oneadmin user) it
says that:
p, li { white-space: pre-wrap; }
"It is an SQLite file created using other tools", and I can't open it. Also,
running oned start (when the backend at oned.conf is set to MySQL) results in
the following:
~> oned start
~> #Aborting oned, MySQL support not compiled!
(although I CAN run onevm list, which is kinda odd to me.)
IMPORTANT NOTE: I only wanted to use MySQL as backend because I use my (only)
host machine as the NFS server (sharing /var/lib/one), and the front-end acts
as the NFS client, and the documentation said that using SQLite in this case
can cause problems. My question: is it such a very important matter, that I
wont be able to work with my host as the NFS server + SQLite as the backend?
I'm using OpenNebula only on a small infrastructure, for a faculty research
project.
oned.log contains the following:

Re: [one-users] application integration (service publishing) in OpenNebula?
Hello Fabian. Thanks again for your reply. I really appreciate you for taking the time. I read what you wrote a couple of times, and (I think) it helped me to clarify some things. But still, I have a few questions and issues for which I am looking for a clear answer. I put them in bullets: As I understand so far, OpenNebula has two types of users: the administrator, who basically has control over "everything", and the users, who can authenticate securely, instantiate some VM's, and do the work necessary for them. My question: can OpenNebula have another "layer" of users, some kind of "end-users"? What I mean is: suppose I, as a user of OpenNebula, using my created VM's, create a Web Service, which I publish on the Internet. Can anyone access this (someone who has no idea about the private cloud, someone who is simply accessing the URL), and by this way uses my Web Service (created on the VM's by the means of OpenNebula), so, basically, uses OpenNebula "remotely" (without knowing it)? Or this just doesn't make sense, since the whole idea of a private cloud is not to provide/publish information and services to the outside world, and this is not even possible since the virtual context?Are the most important reasons for installing OpenNebula the performance needs? Is there any other reason because of which I may want to install it, besides the fact that I might need multiple VM's (that I can manage) to perform a task (and to achieve platform interoperability)? I mean this has be the main point of it, right?When the load reaches its maximum (on a task which a user tries to perform on OpenNebula VM's), are new VM's created automatically (it the physical resources allow this) to support the performace needs? Or the only way of creating VM's is the "manual" one?Can OpenNebula be installed on any type of physical network, or does it have some special needs? Suppose I have an intranet in a company environment, with more interconnected physical machine that I'm actually going to use, does this change anything? Do I have to set up a separate physical network for the physical machines that I'm planning to include in the private cloud? That's it for now, I don't want to ask for too much information all at once.:) I really hope that these questions are easy-to-answer for a professional, and will not take much time (for you Fabian, or for anyone else who thinks that can help me). Thank you, and waiting for your response, Biro Lehel. --- On Sun, 12/11/11, Fabian Wenk wrote: From: Fabian Wenk Subject: Re: [one-users] application integration (service publishing) in OpenNebula?

It is just a container (eg. a virtual computer) where you can install the OS of your choice. The installation of your application inside the OS of your VM needs to be done the same as you would do it on a physical computer. But the installation of the OS in the VM needs to be done first. See my recent posting "Re: Creating virtual machines from scratch" [1] to this mailing list.

An example: If you have 3 computers, you can install on each one the OS of your choice and run it, but then you have only 3 concurrent running OS installation available. With OpenNebula you need to install Linux on all 3 computers (1x front-end and 2x cluster nodes). The cluster nodes also need to support some kind of hypervisor (eg. KVM or XEN). Then you install OpenNebula on the front-end and then adjust the configuration for the shared file systems to be used by the cluster nodes. Then you can create VMs (virtual machines / virtual computers) and deploy them through the front-end (with Sunstone you also have a web GUI).

Re: [one-users] application integration (service publishing) in OpenNebula?
Hello again. Does this application which you would like to offer to clients already exist, or is this something you are developing? As far as I understand it, you would like to create something like Google Apps and then offer it to potential customers, right? Yes, it is something that we're developing. And we are looking for a way for it to be "publishable" (if there are some special settings or criteria for such an application to be run inside the cloud). It will not be a business solution though, we are only doing some experimental research.Not directly, but through the setup with pre-installed VMs which could be started on an as needed basis. But in this VMs your "(cloud) application" needs to be installed and able to run. This is what I've been referring to. I will have OpenNebula set up, and (as common sense would tell) I will have my application installed on the created VM's. My question only referred to: how can I install an application on these VM's (should I only just copy it, or is it more complex than this), or stuff like: can the different tiers of the application (interface, business logic, and data repository) be on different VM's, but most importantly: how can an end-user (not the administrator, but a potencial client) use the application? Or there is no such thing as the "end-user / client" concept in OpenNebula, since the only user is the administrator who has control over the infrastructure? If OpenNebula provides IaaS support, I suppose this means that he does not have control over the application only as a service, but rather he, as the admin, has control over the whole "physical" application?

Re: [one-users] application integration (service publishing) in OpenNebula?
Hello Fabian. First of all, thanks for your answer. So, are you telling me, that there is no way for an application to exploit the advantages of OpenNebula? What is the use of it then? :) Basically, all I want to do is the following: when I will have OpenNebula set up and running (on a small scale), I will try to experiment and exemplify its benefits, by the means of an application that uses the private cloud. Tests, performance benefits, see how the nodes communicate, etc. But I don't understand exactly how a web application (for instance) is made and written such that it can use OpenNebula, it can exploit the benefits of the running VM's, so that it can be more performant. How is this whole integration done? How can an application make use of OpenNebula? Couldn't it be "published" somehow, such that its final users (clients) could use it as a service (through OpenNebula), in a way that is totally transparent to them? I think what I'm referring to is exactly this "communication with the outside world" that you were writing about. I hope I will get some enlightening.

With OpenNebula you will get a framework on which you can run virtual machines (VMs). You will need to create this VM systems yourself and then deploy it on the OpenNebula Cloud. The network configuration can be done very flexible, eg. when using VLAN you could have several network segments on your cluster node, and those through the bridged interfaces also on the running VMs. Access to the outside world only depends on your network setup.

[one-users] application integration (service publishing) in OpenNebula?
Hello. Suppose I have successfully set up a private cloud using OpenNebula. It is only an experimental approach, so I only have 3 phyisical machines: a main node and two cluster (worker) nodes. My question is the following: I have a three-tier (interface, business logic, data logic) web application, which I want to integrate in OpenNebula (that is, to publish it as a service). How can I accomplish this? Also, can I publish it as a service only, or as a whole application, too? Can I pulbish only its interface? Or what are the other existing possibilities in which the users of the cloud can "see" my application (if there are any), I mean, what possible control can they have over it? Also, what needs to be done on each node to accomplish my goal? Thank you very much for your answers, Lehel. ___ Users mailing list Users@lists.opennebula.org http://lists.opennebula.org/listinfo.cgi/users-opennebula.org
[one-users] installing OpenNebula: system requirements?
Hello everyone! I'm new here, but hopefully will try to be a regular member in the next few months. To start with, I have a very simple question: what are the system requirement for a machine on which I'm trying to install OpenNebula? Since I will be working in partnership with an IT company on my project, they need to know the parameters of the machine I'm going to work on (including OS, CPU performance, memory, all necessary software, etc.) This information was not specified on the official website, that's why I'm trying here. Also, do I need further physical machines (worker nodes), in order to experiment with OpenNebula, or could I just install several VM's on the already existing (main, cluster) node? I need to know how many physical PC's I need. In the starting phase, I only need to experiment with the cloud, and see what and how happens, possibly through integrating a simple appication (so you don't have to think of very complex stuff). I think these questions are really simple to answer if you have basic knowledge in the domain, so hopefully someone will be helpful enough to provide me with an answer. Thank you in advance. Hope you all have a good day, Biro Lehel. ___ Users mailing list Users@lists.opennebula.org http://lists.opennebula.org/listinfo.cgi/users-opennebula.org
