Hi,
i found that: https://dustymabe.com/2015/01/11/qemu-img-backing-files-a-poor-mans-snapshot...
I tried it and it seemed to work, although my root fs was checked after the commit, anything else seemed to work. What do you think of this procedure ?
Instead of 'qemu-img create', I'd suggest using `virsh snapshot-create-as` (as shown in my previous email). This will tell libvirt to automatically use the just created QCOW2 overlay. But yeah, one useful bit is to use the `virt-xml` tool to point to the desired disk image (instead of `virsh edit` that I mentioned in the previous email): $ virt-xml F21server --edit target=vda \ --disk driver_type=raw,path=./A.raw -- /kashyap
