[caohf]

HI:
Here is a document for virsh-install ,this command can help you create a image file.

After you finsh the installlation,you can import the  image file into opennebula via sunstone.

Hi Dennis,


When Opennebula shutdown a VM, it will destroy the XML file on the host, and unregister the VM from KVM.


If you just want it to stop, so that you can do something to the image, eg. making a backup, you can use the command


onevm suspend <vmid>


then the VM will still be available in the host, and can be queried by virsh list command.

Hi Dennis,


Opennebula is still using libvirt for KVM-based nodes.


You can still stop/start the VM using normal virsh command, such as virsh stop, virsh start, virsh attach-device etc.


But doing so directly to the VM, will cause your VM to not shutting down properly if you onevm shutdown from Opennebula later. That's what I have experience before.


Thanks.
