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,
