Hello,<BR>
<BR>
I think Dan is right as I had the same kind of problem earlier. I fixed this issue by following a Dan's advice on another bug involving performance issue. You can find the fix in a previous message on this list:<BR>
<A HREF="http://www.redhat.com/archives/fedora-xen/2007-April/msg00166.html">http://www.redhat.com/archives/fedora-xen/2007-April/msg00166.html</A><BR>
<BR>
The key is to mount /var/lib/xenstored in shared memory to limit som I/O overhead.<BR>
<BR>
Maybe it should help you too.<BR>
<BR>
Regards,<BR>
<BR>
