Hello, 

When I snapshot a vm( hvm centos ) the first time, it succeed. There is a 
snapshot file on disk and the vm is  running.  But when I do it the second 
time, it fail for timeout.

This error happened when I used xen-4.0.1-rc5 and  kernel-2.6.31.13. Today 
I update to  xen-4.0.1 and kernel-2.6.32.25, it is with the same wrong.

Error message: 
[root@localhost ~]# xm save -c 2 snap1
Error: Timeout waiting for domain 2 to suspend
