I really don't know, I think it will update the snapshot or new datas will be lost at vm reboot.
That mean you can't rollback at the point of the snapshot if you work on it.
I'll tell the question to sheepdog mailing.

yes, for other storage we need to rollback, like qemu-img snapshot -a or rbd rollback command.

And this does not modify the snapshot?

And how do we specify that for other storage types? Or do we simply run 
externals commands like 'qemu-img snapshot -a'?
