Hi,
I intend to build VM clusters for high-performance computing by OpenNebula.
Each cluster shares /home by NFS and run MPI job individually.
And I would provide them as private cluster to several users.
I expect that NFS configuration can make using some way.
(e.g. static config in VM image, dy

We have a "virtual" HPC cluster, using the SGE,
and the nodes register themselves as SGE hosts during bootup.

Hi,
You can also create an empty image with a template similar to this one (see
[1] for more info):
NAME = new_img
TYPE = DATABLOCK
SIZE = 512000
FSTYPE= ext3
Or create an empty disk instead, as explained in [2].
You can change the boot device with the OS/BOOT
Hello,
Is there a way to know the "vmid"
"oca.VmTemplate.instantiate(name='name')" is going to assign to the
virtual machine?
And
Can you retrieve the content of a template from oca so it can be used in
"oca.VirtualMachine.allocate(client, template)" ?
Thank you.

That sounds fine. I consider using SGE.
I have a little worry that using
When I shutdown a VM in Sunstone, the state of that machine is shutdown.
What's the purpose of this operation? I mean when a VM is shutdown, user
can do nothing to that VM ,except delete, saveas or resubmit that machine.
I cannot boot that VM again. It seems a shutdown VM is useless.

You cannot create an image with Sunstone. You should create an image with
kvm.

Hello folks .,
Quick question ..

Hello Richard,
you're right. At some point we had some issues with libvirt and kvm, and
the way they handle disk image files ownership and permissions, that's the
reason why we have those chmod's. However we can remove them provided that
the opennebula administrator configures libvirt properly to
Hi,
VMware Server is a not stand-alone hypervisor, previous to ESX.
OpenNebula doesn't currently support full integration with vCenter,
although there is work in progress to use it to provide livemigration
capabilities with vMotion through OpenNebula.
For now, the alternative is to manage each ho

Hello Nikolay
Just a little correction concerning Linux distros. There is no ES/AS
in RH version 6.0 - just RH 6.0 32/64 bit.
I think ES/AS ended with RH version 4.0. It was a concern of RAM
limitations of 16GB in RH ES 4.0.
BTW:
I would not recommend your setup / IT-softwareinfrastructure as yo

Hi,
A VM in the SHUTDOWN state is waiting for the OS to gracefully shutdown.
The VM life-cycle ends when the VM reaches the DONE state.
To boot the same guest machine again, just create another instance of its
template (onetemplate instantiate).
More information on the VM life-cycle:

Hi,
I've done some more investigating and I've got a handle on what the problem is.
My VM templates don't define a CPU attribute (as I'm just letting it
use the default values) and therefore the code errors out trying to
get a CPU value from my vm template which don't have one.
This sounds like
