Hi,
i have a two node cluster with virtual guests as resources.
I'd like to snapshot the guests once in the night and thought i had a procedure.
But i realize that things in a cluster are a bit more complicated than expected

I will shutdown the guests to have a clean snapshot.

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,

Hi list,
The tl;dr; is: with Libvirt/QEMU, should it be possible to mount a
filesystem share (of type='mount') after restoring from a snapshot that
was taken when the filesystem share wasn't mounted?
It's pretty clear that Libvirt/QEMU
Hi Eric,
Thank you for the reply, yes indeed the qcow2 file takes only a few GB on
disk.

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).

somewhat bigger than the maximum size of the disk.

If you've created external snapshots, then all the files should be under
/var/lib/libvirt/images/
Here's just a quick test I did on my laptop:

That depends - did you create an external or an internal snapshot?
'virsh snapshot-info Windows Windows' will help.
> I understand that the principle is that when changes
Firstly I'd like to learn where a snapshot is stored once it has been
made. I understand that the principle is that when changes occur in
the VM, the difference is written to the snapshot, thus recording the
differences between the date/time of the snapshot and the current
value of the VM. Is tha
