[libvirt] Ability to add arbitrary data to snapshots

[Alexander Burluka]

Hello!

Currently our Virtuozzo company is working on some kind of management 
tool for libvirt. We encountered some problems with snapshots while 
development.
So I would like to ask community a few questions:
1) Would you mind if I extend current libvirt snapshot with ability to 
add arbitrary data (blob or some config files)?
2) Would this feature be useful for your users?

I see it as something like:
virsh snapshot-create VM1 --blob /path/to/some-file
virsh snapshot-revert  VM1 <number>
and /path/to/some-file appeared again.

Looking forward for your comments and help.
Thanks!
