[Xen-users] DomU crashes on reboot -- with hack-fix included...

Hello, 

on a single-processor-amd64-machine running Xen 3.0.2 (or Xen-testing
as of this noon) reboots of domU don't work if another domU is using
much CPU.  The domU which has just been re-started panics saying that
it cannot mount it's /-filesystem.  
I suspect that this is a race codition (which happens to not occur very
often), as the attached patch to Xend (wait 5 seconds before
re-creating the domain and unpausing it) fixes it.  

Any comments, or thoughts on what might be the problem with the Xend
code?  I noticed that when rebooting a domU, there is never a line
saying "(DevController:132) Waiting for devices vbd" in the Xend log,
as is when creating a domain.  Might this be the problem?

Regards,
Milan
