[Xen-users] Snapshot fail, when I snapshot a vm the second time.




Hello,

When I snapshot a vm 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.
Can  snapshot a vm sevral  times?  If can , what's wrong with it?

xen : xen-4.0.1-rc5, kernel : kernel-2.6.31.

Error message:
[root@localhost ide]# xm save -c 8 dom8_2.snap
Error: Timeout waiting for domain 8 to suspend
Usage: xm save [-c] <Domain> <CheckpointFile>

Save a domain state to restore later.
  -c, --checkpoint               Leave domain running after creating        
                                 snapshot
