Backing Up virtual Machines

Backing Up virtual Machines

[Thomas Glanzmann]

Hello,
with VMWare ESX Server you have VMware Consolidated Backup. Which
basically does the following:

        - Do a Snapshot.
        - Pull an atomic state of the disks.
        - Delete the Snapshot.

Does somone does that with kvm or qemu already and maybe has a script
for me or points me to something I can use. I want to backup running
virtual machines from the *host* Operating System.

It should be easily doable.  Start qemu with the monitor listening on a 
unix domain socket, then use socat (or however it's called) to issue the 
snapshot creation and deletion commands.

It may also be doable with virsh, provided it exposes the snapshot 
capabilities.
