And here is the mail again.. Part of the mail was stripped off (I had those
".\n" lines in message body).

Hi,

Sometimes the dom0 seems to hang but domUs are running. HVM machines also
hang (probably because of dom0 hang). And this just happened again.

Because domUs were running, I decided to shut them down before resetting the
dom0. I then shut the first domU down (ssh'd to it and told to 'poweroff')
and next thing I saw the dom0 was alive again (pending ssh connection to dom0
established).

>From /var/log/messages* I found following:

This has happened more than once but not very often. Maybe this is HVM
related issue as now it happened when I was playing with the HVM (with 
rdesktop to Windows XP HVM)..

XEN used is 3.0.4:
xenkernel30-3.0.4   Xen3 Kernel
xentools30-3.0.4    Userland Tools for Xen
xentools30-hvm-3.0.4nb1 Tools for Virtual Machine Extensions support in Xen


Any suggestions?

Thanks,
