Hey Wido, Perhaps you know the answer to this:
My main interactions with KVM have been in the form of data disks. I create a LUN on my SAN that gets passed to a VM as a data disk. In this situation, how would a snapshot of such a disk work? On XenServer and ESX, your data disk can be just a subset of the overall LUN and hypervisor snapshots create new virtual disks that are stored right next to the original ones on the same LUN. I'm un-clear how this works in KVM. Thanks!
