XEN HVM domU Problem

Hi All,

Running OpenSUSE 11.1 on the latest patch level the following error keeps annoying me:

Start a HVM Domain, let it run some time

restart it from the VM (reboot issued on the “guest” system)

you get:

domid: 27

I/O request not ready: 0, ptr: 0, port: 0, data: 0, count: 0, size: 0

in the log.

After a reboot, everything is up and normal again.

On the prompt it claims:

“Device 768 (vbd) could not be connected”

This is reported to be a bug since Feb 2009 but obviously hasn’t been addressed by OpenSUSE.

Any idea?
