[one-users] How to get information of actual VMs from inside a cluster

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

Re: [one-users] Creating virtual machines from scratch

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

[one-users] Oca 3 template instantiate

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.

[one-users] [Question] What's the purpose of Shutdown operation?

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. 2011/12/9 richard -rw- weinberger > Hi! > > I'm a bit confused how to create a vm from scratch. > Assume I want a vm running with CentOS6 and a new virtual hard disk of > 500GiB. > > How can I create a new disk using

Re: [one-users] Security issue: world writable files

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

Re: [one-users] Mixed mode UBUNTU+ RH KVM

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

Re: [one-users] [Question] What's the purpose of Shutdown operation?

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: http://open

Re: [one-users] Error from quota module when trying to create a vm or instantiate a template

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
