How do I make a persistent domain with virsh?

  • 772

virsh create somefile.xml creates my machine just fine but when I shut the machine down the whole thing disappears. Machines I made with the virt-manager GUI are persistent (stick around after shutdown) and the xml file is derived from those virt-manager created machines.

libvirt rhel6 virsh

    Use virsh define somefile.xml and virsh start domain-name, doing this the VM will be persistent. I can't check right now, but I think you can use virsh define on an already started VM and this will make it persistent.

  2. If you don't have the xml for the running vm (eg. after transient migration), you can do

    virsh dumpxml vm_name > vm_name.xml
virsh define vm_name.xml

    To check:

    virsh list --all --persistent

    The VM should now be listed. Or

    virsh dominfo vm_name

    There should be a line with 'Persistent: yes'.
