Hi, I ran into a strange behavior with libvirt snapshots. I have some vms running with thin-provisioned qcow2 disk images (libvirt 1.1.3 with fedora 20). * When I create a snapshot on the VM, the qcow file suddenly grows big, somewhat bigger than the maximum size of the disk. * When I delete the snapshot, the allocated disk space is not freed up, the qcow image remains the same size. However, if

...be convenient for having only one file to worry about, but they also come with drawbacks (at one point, qemu had a bug where taking 2 or more internal snapshots could DRASTICALLY slow down operations of the file) and aren't as well tested by qemu folks. These days, most people prefer external snpashots (you have to manage multiple files, but the RAM state is kept separate from disk state, and cleanup is a LOT easier because you merely delete the files you no longer need, instead of trying to defragment within a file you are still using). -- Eric Blake eblake redhat com +1-919-301-3266 Libv...

Good m/d/n guys, wanted to put idea through you before trying to implement this. So afaik LVM snapshots basically don't take any "real" space on hard drives. I'm using KVM virtualization on my hosts and let's say i create an LVM volume for my linux VM, then install it properly, shut it down and take LVM snapshot of it. Basically i've just cloned it (LVM2 snapshots are

hi Martin, thanks again for the feedback. maybe you have noted that I am not yet all too familiar with those tools. this is now sort of working for me. But I sense that you seem this method to be less then ideal. Reading through the virsh manual it looks like ... $ virsh snapshot-create [domain] --disk-only --live ... might be doing a similar thing. Maybe more elegant (pure virsh) and on a
