Re: [one-users] 'onevm saveas' via XMLRPC or OCCI???

2011-02-09 Thread Carlos Martín Sánchez 
Hi Marco,

The XML-RPC call requests an image id because the image has to be created
beforehand.
You can check how it is done in the oneimage command (it's a straight
forward ruby script), and then replicate the same steps in your code.

Regards,
Carlos.

You're wrong! The OCCI requests are handled by occi-server.

Re: [one-users] HELP installing opennebula in opensuse 11.3

2011-02-09 Thread Héctor Sanjuán 
Hi, it works for me with the following ssh related packages on a 32bit
machine:

rpm -qa | grep ssh
libssh4-0.4.2-1.19.i586
yast2-sshd-2.18.0-5.2.noarch
sshfs-2.2-5.1.i586
libssh2-1-1.2.6-6.1.i586
openssh-5.4p1-8.2.i586
openssh-askpass-5.4p1-8.2.i586

The only difference is that i have libssh4 in addition to libssh2.
Perhaps you can you try installing that one and see if that solves the
problem...

[one-users] Cannot launch a Second VM in XEN Node with LVM

2011-02-09 Thread anoop Lekshmanan 
Hi,

I have successfully launched a VM on XEN node with LVM. However when I try
to launch another instance, ONE tries to create LV named lv-one--0 which
already exists as ONE created it for first VM.

vm.log:

 Creating LV lv-one--0
Wed Feb  9 17:00:01 2011 [TM][I]: tm_clone.sh: ERROR: Command "/usr/bin/ssh
ast-wks-348 /usr/bin/sudo /sbin/lvcreate -L20G -n lv-one--0 vg00" failed.

Is this a ONE bug?

Any help would be appreciated.

Hi Ruben  ,
thanks for answer ,

But if i have 10 kernels and 10 nodes , is there any easy way to

2011-02-09 Thread Ruben Diez 

Hi Zeeshan

You MUST put the kernels in all the nodes. You can use the parallel-scp 
stuff or export them to all the nodes by NFS... It is your decision... 
The concrete mechanism is not the matter... The important stuff is to 
make kernels accessible by all the physical nodes

its not solving the problem...
i try to install libssh4

# zypper in libssh4

after sucessfully installing libssh4, i try to install opennebula

# zypper in opennebula

Loading repository data...
Reading installed packages...
Resolving package dependencies...

Problem: nothing provides ssh needed by opennebula-2.0.1-1.1.x86_64
 Solution 1: do not install opennebula-2.0.1-1.1.x86_64
 Solution 2: break opennebula by ignoring some of its dependencies

[one-users] Using LVM as storage option.

2011-02-09 Thread Leong Marco 
Hi all,

I'm new to OpenNebula, and I does not get a clear idea from official 
documentation about LVM deployment. I have a few questions that I would like to 
be answered.
How do I register an virtual machine image template in LVM?
Is it possible to add existing virtual machine which is currently using LVM as 
storage into OpenNebula, and how could I do that?


Thank You !!

Best regards,
Leong Marco

[one-users] New sharedlvm Transfer Manager driver

2011-02-09 Thread Roberto Sassu 
Hi all

me and Paolo developed a new Transfer Manager driver in
order to add support for LVM on a shared storage
repository. 
Please consider this driver is in a very early development
stage, so it is not guaranteed it works for all possible
configurations.
Another important thing is that, because this driver uses
LVM without the clustering extensions, it may be possible
to experience LVM metadata corruption (however, this
never happened in our test cloud).

This driver requires:

- iSCSI target on one node (IMPORTANT!! Add this option: write-cache off);
- iSCSI initiators on all nodes (frontend + other cluster nodes);
- LVM with file-based locking enabled.

Steps required to enable the driver:

1) Edit the configuration file /etc/lvm/lvm.conf in the host that exports
the device and set the "filter" parameter by replacing the involved line 
with:

filter = [ "r||" ]

This is required in order to prevent LVM to access the exported device 
without
passing from the iSCSI interface.


2) Extract the content of the attached tarball to $ONE_LOCATION;

3) Set the LVM volume group name in the file 
$ONE_LOCATION/etc/tm_sharedlvm/tm_lvmrc
 by editing the variable VG_NAME;

4) Add these lines to the configuration file $ONE_LOCATION/etc/oned.conf:

TM_MAD = [
name   = "tm_sharedlvm",
executable = "one_tm",
arguments  = "tm_sharedlvm/tm_lvm.conf" ]


5) Remove all cluster nodes added with the "onehost" utility;

6) Re-add all cluster nodes to the cloud by executing:

onehost createtm_sharedlvm


6) Enjoy it!


Regards

Roberto Sassu
Paolo Smiraglia

Re: [one-users] Incomplete information from hosts polling (VMWare ESXi 4.1 an OpenNebula 2.0.1)

2011-02-09 Thread Luigi Fortunati 
Thanks Tino,
That is probably more a problem of libvirt, since VMWare IM Driver use it in
order to access information about the hosts.
In order to get information about the hosts OpenNebula launches a virsh
command and parses the output.
The script that does this work is located in $ONE_LOCATION/lib/remotes/im
and the output of the virsh command is:
oneadmin@custom2:~/lib/remotes/im$ virsh -c esx://
custom6.sns.it/?no_verify=1 nodeinfo
Enter username for custom6.sns.it [root]:
Enter root's password for custom6.sns.it:
CPU model:   AMD Opteron(tm) Processor 246
CPU(s):  2
CPU frequency:   1992 MHz
CPU socket(s):   2
Core(s) per socket:  1
Thread(s) per core:  1
NUMA cell(s):2
Memory size: 2096460 kB

I always get the same output, no matter how many VMs are running on the
cluster node.
That is why OpenNebula returns with an output like this:

oneadmin@custom2:~/var/96$ onehost show 1
HOST 1 INFORMATION

ID: 1
NAME  : custom6.sns.it
CLUSTER   : default
STATE : MONITORING
IM_MAD: im_vmware
VM_MAD: vmm_vmware
TM_MAD: tm_vmware

HOST SHARES

MAX MEM   : 2096460
USED MEM (REAL)   : 0
USED MEM (ALLOCATED)  : 0
MAX CPU   : 200
USED CPU (REAL)   : 0
USED CPU (ALLOCATED)  : 0
RUNNING VMS   : 1

MONITORING INFORMATION

CPUSPEED=1992
HYPERVISOR=vmware
TOTALCPU=200
TOTALMEMORY=2096460

OpenNebula polls cluster nodes periodically and gets only information about
hypervisor type, cpu frequency, total cpu, total memory size.
The limitation here is caused by libvirt (virsh) which is unable to return
more information about the actual usage of resources.

The integration of OpenNebula with Xen can rely on ssh access to the cluster
nodes.
The IM Driver for Xen hypervisors, launches xentop on every cluster node in
order to get information about the VMs and then parses the output.
As an example here is the output of commands xm and xentop (some info is
purged):
custom9:/ # xentop -bi2
  NAME  STATE   CPU(sec) CPU(%) MEM(k) MEM(%)  MAXMEM(k) MAXMEM(%)
VCPUS NETS NETTX(k) NETRX(k)
  Domain-0 -r1020.01930260   93.7   no limit   n/a

free_memory: 135
free_cpus  : 0
max_free_memory: 1508
max_para_memory: 1504
max_hvm_memory : 1492
[...]

The script $ONE_LOCATION/lib/remotes/im/xen.d/xen.rb parses those two
outputs and retrieves data about memory, cpu, and network usage.

I think that VMWare drivers are scarcely useful if they can't provide the
degree of information which can be achieved with xen hypervisors and
OpenNebula, I've tested the effects of this issue in my tests.

[one-users] Node install

2011-02-09 Thread Jan Mario 
Hello!

My OpenNebula 2.01 frontend is running on an OpenSuse 11.3 32 bit OS.

I'm trying to setup the (worker) nodes on servers with a OpenSuse 11.2
64 bit OS. The servers exist and are already XEN enabled.

I've installed OpenNebula on  the  frontend system wide.

Now I'm wondering what to install on the nodes. The documention is not
clear about it. While there's a package opennebula-node for ubuntu,
there's nothing similar for opensuse or other OSs.

so do i have to install the complete opennebula package (with all the
dependencies) on the nodes?

thanks

jan

OpenNebula supports changing scheduling policies [1] using rank and

system implemented for cpu and memory [3] but is can be easily
modified to cope with more resource constraints [4].

Re: [one-users] SSH error

2011-02-09 Thread Javier Fontan 
That is possible but that will lead to huge amount of hacks as you
have to do this (at least):

* Parse the deployment.0 file or call back to opennebula to ask for
the source kernel/initrd files. TM knows nothing about kernel/initrd
* Rewrite the deployment.0 file to point to the newly copied
kernel/initrd in the node
* Take care somewhere in the stack to copy the kernel/initrd file for
livemigration (it wont work without shared storage anyway)

Why don't you just use pygrub?

Hi,

You should have  Xen/KVM/VMware properly configured on the node.

Then
install ruby. I used 'yum install ruby' on CentOS.

Then on the front end get the UID of OpenNebula user and add the same user
in node with same UID and GID. Then create passwordless ssh.

groupadd -g 503 cloud
useradd -g 503 -u 503 oneadmin

[one-users] sha1.so Issue

2011-02-09 Thread Ivan Bronsky 
Hi,

I installed OpenNebula 2.0.1 on Centos 5.5. from rpm. I can start the deamon
with  $ one start.
But after oneuser, onehost, onevm etc. commands, I have message like this:

[root@nebula home]# oneuser list
/usr/local/lib/ruby/1.8/x86_64-linux/digest/sha1.so:
/usr/local/lib/ruby/1.8/x86_64-linux/digest/sha1.so: undefined symbol:
rb_Digest_SHA1_Init - /usr/local/lib/ruby/1.8/x86_64-linux/digest/sha1.so
(LoadError)
from /usr/local/lib/ruby/site_ruby/1.8/rubygems/custom_require.rb:31:in
`require'
from /usr/lib/one/ruby/OpenNebula.rb:7
from /usr/bin/oneuser:30:in `require'
from /usr/bin/oneuser:30

I suppose that this could be related with the ONE_AUTH variable. I created
/root/.one7one_auth file which contains "oneadmin:" where password
is those which I created for oneadmin user prior the software installation.
Anyway, this detail is not clear from the documentation.

Thanks,
Ivan

Thanks for your reply; I've found the MM scheduler and per-user quotas
but what I'm trying to found out is if there is something like
VMWare's reservations and priorities, see e.g. page 78 of:

http://www.vmware.com/pdf/vsphere4/r41/vsp_41_vm_admin_guide.pdf

(docs home at 
http://www.vmware.com/support/pubs/vs_pages/vsp_pubs_esxi41_i_vc41.html).

Re: [one-users] VM quotas and priorities?

2011-02-09 Thread Javier Fontan 
I am not familiar with VMWare nomenclature but from what I see in
those documents reservation relates to the minimun cpu available for a
VM. That feature is directly related on how the hypervisor manages VMs
(hypervisor scheduler). Our xen drivers use the ammount of CPU you
specify (e.g. 0.5) to set credits in the xen credit scheduler [1]. We
use a fair share scheduling (weight), not capping the maximun cpu a VM
can consume. When VM's are competing to use CPU resoirces this values
are use to enforce fair share of available CPU. If there is no
overcommitment then that CPU value will set the minimun cpu a VM could
use.

I really could not understand the priority part but the document
linked mentioned IO prioritization. If that is the case it is not
supported out of the box but take into account that OpenNebula is
modular and easily modified extended. I think that IO throttling can
be accomplished adding ionice calls on VM creation.

Re: [one-users] Client libraries for OpenNebula

2011-02-09 Thread Javier Fontan 
Right now theres no automatic method of client only installation. You
will have to manually copy clients and required libraries
($ONE_LOCATION/lib/ruby). There's a ticket open to deal with this
problem [1] and we hope to have a solution soon.
