[libvirt] [FYI] Skript to extract qcow2 snapshot info to libvirt snapshot xml

[Philipp Hahn]

Hello,

I sometimes get foreign qcow2 images with embedded snapshots. Without the 
corresponding XML files libvirt doesn't recognize them. Therefor I created 
the attached script to fake-create the missing snapshot XML files.
Be advised that the XML files might not work in all cases, especially when the 
configuration was changed between snapshots, but at least I prefer a solution 
working 95% of the times instead of 0% ;-)
And since I already wrote it, others might find it useful as well.

Sincerely
Philipp Hahn

PS: An a drink of their reasonable choosing to the first one writing a 
qemu-img version printing (shell-)parsable output :-(
