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...
