This looks good to me, thanks.

Ian/Wei do you have any comments? xapi folks?

Looks good to me.

Wei.

I looked to the project of domain snapshot and seems good.

I have only a question.
I saw this:
Disk snapshot can be created by many external tools, like qemu-img,
vhd-util and lvm, etc.
Wouldn't it be good to also use btrfs for external disks snapshot?
Even if btrfs snapshots works on subvolumes (directories) it is possible to atomically creates a copy-on-write snapshot of a file (with domUs disks on file, including raw) with btrfs clone operation (reflink systemcall, eg: cp --reflink source dest)
