Re: [one-users] iscsi target as a guest disk

[one-users] 回复: Re: application integration (service publishing) in OpenNebula?
Hi,Biro You raised many questions. Some are openNebula specific and others seems general to all cloud computing environments. 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? To my understanding, this is a general question for all clouds. A cloud must have users to manage and maintain the cloud itself(cloud infrastructure), such users ard administrators. A cloud should also have cloud customers to which the cloud provide services(e.g. VMs, storages). Such users are cloud users who can login into the cloud and use cloud provided resources. The last kind of users are application users who are the customers of your applications. OpenNebula cann't know such users in advance, so it doesn't provide any mechanism to support this kinds of users. (These are just my personal understanding!) 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? The main reason for using cloud is have many characters: on-demond self service, improving physical server utilization and so on. you can refer to this cloud definition to have a deeper understanding: http://csrc.nist.gov/groups/SNS/cloud-computing/index.html 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? untial now, OpenNebula can't do such job automatically, but you may implement such function based on it. (in fact Amazon EC2 have implemented such functions). 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? OpenNebula can installed smothly to ethernet physical networks (I am not sure exactly about other types of network).

Re: [one-users] application integration (service publishing) in OpenNebula?
Answers inline. 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? As Fabian said, consider each VM as a normal machine. Anything you expose on it through a network will be visible, just as with a normal machine. The idea of a private cloud is to hide the physical location of the virtual machines (on what computer does each reside) and hide the fact that the VM is not a physical machine. 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)? OpenNebula is a hypervisor for hypervisors. The reason you want to install it is to provide a means of managing a cluster of servers which provide virtualization. OpenNebula most importantly allows migration of VMs between physical machines and resource usage monitoring. 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? I think you miss the point of what a cloud manager or a virtualization middleware does. See OpenNebula as a middleware over simple virtualization mechanisms such as KVN, Xen, HyperV, etc. OpenNebula only provides a means of managing heterogeneous virtualized environments. Automatic scaling of virtual machines is out of the scope of this middleware. The basic idea is that a VM is created, deployed, and the life cycle of the VM is monitored using OpenNebula. The VM can be started/stopped/migrated but automatic scaling is not possible, due to different factors, among which the unavailability of such a mechanism on the underlying hypervisors (only XEN allows changing the VM allocated memory without recreating the machine). Any scaling mechanism should be built on top of OpenNebula. 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? If you read the OpenNebula documentation, the only requirements are that a bridge exists on each OpenNebula node to connect the virtual machines. To what that bridge connects, it is up to the infrastructure provider, but no special requirements are needed in terms of network for the VMs. The live migration mechanism requires a storage NAS and that can influence the network, but mainly any network will do fine with OpenNebula.

Re: [one-users] iscsi target as a guest disk
Hi, you should use tm_shared instead of tm_ssh (tm_lvm won't work either for your setup). Regarding your first issue: managing iscsi targets with OpenNebula, there is no native way to handle iscsi block devices with OpenNebula. What you can do out-of-the-box is to use any block device available in the target host (just like you're trying to do in the above logs), whether it's iscsi or not. However I reckon that's too limited for your scenario, since it requires an administrator to discover the iscsi targets on the target host. We've opened a ticket to provide native support for iscsi targets (planned for OpenNebula 3.4): http://dev.opennebula.org/issues/1032 We've been thinking about the possible implementation, and for the moment we believe the best approach will be the following: 1) Define a iscsi handler, such as: iscsi://hostname/target, which will be used in image templates under the SOURCE attribute: DISK = [ TYPE = block, SOURCE=iscsi://my-san/my-lun, TARGET = hda, CLONE=NO] 2) Modify the TM drivers to handle in a specific way sources starting with iscsi:// (just like we did in tm_lvm for /dev/* devices [1]) The driver will run a re-scan of the iscsi targets, and create a symlink for disk.0 to point to the new /dev/ device.

Hi,
I assume you are using the 3.1 development version.
This is a new security feature to prevent users from registering any file
readable by oneadmin.
/var/lib/one is by default a restricted directory, you can configure the
behaviour in /var/lib/one/remotes/image/fs/fsrc, check the Image Repository
documentation for more info [1].
You can also check the new features and main changes in the compatibility
guide [2]

Re: [one-users] does oned check which is the proper host for new VM?
Hi Yes OpenNebula check the capacity of the host and the VM. Maybe there is a misconfiguration in your host or monitoring system. Could you send the output of onevm show and onehost show of the relevant VMs and host? Also, OpenNebula can use several heuristics for VM placement. Take a look at the following page to find out how to configure it: http://www.opennebula.org/documentation:rel3.0:schg Cheers Ruben On Thu, Dec 15, 2011 at 3:11 PM, davood ghatreh davood.gh2...@gmail.com wrote: Hi, I have 4 host servers, and opennebula installed and configured. whenever I create a VM it choose host2, regardless of how much this server remained resources are. for example, I created 10 vms (not simultaneously) and they were all created on host2! If I create other vms, they will be also created on host2! other servers have no load and no vms and they are all enabled in opennebula. how can I make oned to properly decide which host has enough resources to create new vm on it. Another issue is, oned doesn't check VM required resources and compare it to host resources to chose proper host. host2 has 2G of RAM and host4 has 4G RAM. I tried to create a vm with 4G RAM. opennebula choose host2, as always. Then after PROLOG states, it was unable to start the VM because there were not enough resources for this VM on host2. I disabled other hosts in opennebula and just left host4 enabled and resubmit the vm. it successfully created on host4! so, what does really opennebula do about choosing proper host for new VM? have I missed something or it is really a problem with opennebula?

[one-users] x509 Auth Failing after 24 hours
Hi, I am trying to setup OpenNebula with x509 authentication. I am using sqlite as the DB back end for now. I am following the documentation here: http://opennebula.org/documentation:rel3.0:x509_auth I've configured everything correctly as far as I can tell. I can successfully use x509 to login, but after 24 hours (no matter what I set the expire time to with the --time argument) I get error messages saying that the user couldn't be authenticated. I've tried re-running the oneuser login ... command to no avail. The only thing that works is if I delete one.db and restart OpenNebula. Then I can log in just fine, but all the configuration that I have done is lost. What do I have to do to fix this?

Not at all, please allow me to rectify what is a private cloud. A private cloud is a set of infrastructure (machines) that are dedicated to a single entity/ company/ client. The host machines, storage, etc. are not shared. For example you may need a private cloud for privacy or reasons, to meet security standards, or for storing sensitive information. If you're building a cloud internally that will serve exclusively for your company needs, you're building a private cloud (wether it's publicly accessible/ connected to the Internet or not). If you're a service provider and want to offer Private clouds to your clients, you can use OpenNebula VDC to isolate resources and build private clouds (although in that scenario, OpenNebula itself would be shared, and a security breach in OpenNebula could potentially expose your private clouds) : http://opennebula.org/documentation:rel3.0:vdcmngt The NIST has published an interesting document that tries to highlight and demystify what cloud computing is: http://csrc.nist.gov/publications/nistpubs/800-145/SP800-145.pdf Simon ___ Users mailing list Users@lists.opennebula.org http://lists.opennebula.org/listinfo.cgi/users-opennebula.org

Re: [one-users] Removing old VMs
Dear Richard, This is not necessarily an answer to your question, but if you'll consider taking a look at Feature #1026 that I created on the dev site. I can understand that all reference material associated with a VM would remain even when the VM is in the DONE state since technically that is an acceptable state for the VM to exist. There could exist a scenario where the user would like access to deployment files, logs, etc. However, it would be nice if there was a method to clear-out all data related to VMs. That's where Feature #1026 comes in. Currently, even deleting a VM leaves all its files laying around. -- Hutson Betts Computer Science and Engineering Texas AM University On Fri, 2011-12-16 at 00:12 +0100, richard -rw- weinberger wrote: Hi!

On my system the /etc/one/oned.conf belongs to root (rw) with only read permissions for the cloud group.
