Does libvirt support snapshotting when the virtual disk comes from a vmdk file? http://wiki.libvirt.org/page/Snapshots#Desired_functionality seems to say no, since it says "'virsh snapshot', which requires all disk images to be qcow2". OTOH, man virsh, http://libvirt.org/formatsnapshot.html, and http://libvirt.org/formatdomain.html#elementsDisks seem to indicate more flexibility, though I see nothing about vmdk. If there is support for vmdk, is it just for external snapshots, or do internal snapshots work? Currently running libvirt 0.9.12, qemu-kvm 1.1.2 (though I could use vmw...

...where specified. I also tried methods  virDomainSaveFlags with xml configuration string(see below) as parameter  *dxml, but method fails with: libvir: Domain Config error : XML error: domainsnapshot.Unable to create snapshot. What should I add to xml configuration? I look at http://libvirt.org/ formatsnapshot.html on example but I dont know what paths I should use in my program. I dont understand much snapshots and similar stuff so could you give me example how could I edit my xml configuration? Or what I should do to make virDomainSave and virDomainRestore work? xml configuration: <domain type=&...

Is this still missing or have I created an invalid XML? Thanks - Trey

Hello, I want to do a snapshot which the VM has volumes. But I want to skip the volume check when I do the snapshot. (Which means I want to do a snapshot without detaching the volume) So I try to write a snapshot XML refer by http://libvirt.org/formatsnapshot.html as following: vda is my VM basic disk (qcow2) vdb is a volume (raw) ================ t1.xml =============== <domainsnapshot> <disks> <disk name='vda' snapshot='internal'> <source file='/var/lib/libvirt/VM1/disk' /> </disk> <disk name=...
