This patch introduces *untested* snapshot support to libvirt xenlight driver.
The only thing I know about this patch is that it compiles.On the other hand
the API with I had in mind while I made this patch *may* and has already
changed(as of this commit).However due to its turbulent state I prefer not to
update the code until it stabilizes a bit.
