Re: Can't take live snapshot, not supported with this QEMU binary
Under libvirt 1.1.1 snapshot support is incomplete.
Source: http://wiki.libvirt.org/page/I_created_an_external_snapshot,_but_libvirt_won't_let_me_delete_or_revert_to_it
In regard to snapshotting (features and stability), I have selected these versions of libvirt and qemu:
Libvirt >= 1.2.9 (currently 1.2.12)
Qemu = 2.1.0
On Qemu 2.3 and 2.4, I have experienced a regression bug regarding external snapshots. I...

You are right. I am running an old libvirtd but with a new virsh. It
works now! Thank you so much!

qemu-img and editing of a libvirt <domain> XML; more details can be
found on this wiki page (still in a bit of disarray, so feel free to
edit it for clarity according to what works for you):

virsh uses internally qemu-img ?
Hi,
i read that virsh uses internally qemu-img (http://serverfault.com/questions/692435/qemu-img-snapshot-on-live-vm).
Is that true ? so snapshotting a running vm with virsh or qemu-img is the same ?

Virsh snapshots
Hello,
I am working on my PhD thesis and it would be really helpfull if someone
could advise me, whether can Virsh create snapshots of VMs using
copy-on-write.
Thanks for reply.

Snapshots: Where they are stored and how to use them?
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 that a correct assessment of the process?
If that is indeed so, can I take regular snapshots and
