Re: KVM Live Snapshots


VM Snapshots (both disk and memory) are supported on KVM if you have NFS as your primary storage.

See PR https://github.com/apache/cloudstack/pull/977 that was merged for 4.10.

Hi Asai,

You can't do *VM* snapshots - but you can do live *volume* snapshots once you set kvm.snapshot.enabled=true.

    We successfully upgraded to 4.11.1.  One of the main reasons we did this was that we thought this would enable us to do live KVM snapshots of running VMs.  This doesn’t seem to be the case, though.  When I try to snapshot a running VM, I just get the message: "KVM VM does not allow to take a disk-only snapshot when VM is in running state"

    Is there a way currently to do this with Cloudstack and KVM VMs?
