[Xen-users] xm commands hang when a HVM guest is running

[Sebastian Reitenbach <sebastia@xxxxxxxxxxxxxxxxxxxx>]

Hi,

I try to manage a xen cluster with heartbeat. I have most domU's 
paravirtualized, but also two hvm guests, running OpenBSD 4.4.

on a node, where a hvm node is started, then it is very likely, that a xm 
command, doesn't matter which one, just hangs for a long time, e.g. a minute 
or even longer. when I shutdown the hvm guest, then xm starts working fast 
and reliably again. So right now its nearly impossible for me to manage this 
clsuter via heartbeat containing the hvm guests.

Is this known to someone already, and maybe there is sth.  I can do against 
the problem? If I need to provide more information, let me know...

cheers
Sebastian
