I tried the save / restore on the same host and it doesn't work - the
restored VM is not responsive.

I f I try 'xm save' with the VM in this state, I get 'Error: Timeout
waiting for domain 29 to suspend'.


Here's what I get in xend.log when I save the VM (I removed some of the
lines that were 'repeated')::
