[Xen-devel] does 'xm save' compress?

["James Harper" <james.harper@xxxxxxxxxxxxxxxx>]

Does 'xm save' compress the data it writes to disk? Someone on another
(non-xen) mailing list pointed out that the bottleneck to a quick
shutdown/restore that didn't overly interrupt DomU's was the time taken
to suspend the DomU's on Dom0 shutdown and then resume them again on
Dom0 restart, and I can see the point, especially if the data wasn't
compressed and it had to write out every raw byte to disk...
