Hi,I'll test savevm today, qcow2 and "qcow2 over lvm"

I see an (old) interresing (small) patch here,to allow snapshot of disk only.
This patch come from a guy from cloudtack (edison at cloud.com), and they seem to use it

http://lists.nongnu.org/archive/html/qemu-devel/2010-09/msg00655.html

I'll do test writethrough/writeback to see if It can corrupt the qcow2 file.


also for backup purpose, with internal snapshot,we can export an image of a snap version with this command

qemu-img convert -f qcow2 -O qcow2 -s snapshot_name src_img bck_img
