[Xen-users] auto start fails at random

[David Koski <david@xxxxxxxxxxxxxxxx>]

The console is shown below.

Status:
# uname -a
Linux xen 2.6.12.6-xen #1 SMP Mon Jan 23 01:04:26 UTC 2006 x86_64 GNU/Linux

This is a Sun Microsystems SunFire X2100.

I have two domUs and most of the time one or both will fail. Some times
they both boot fine.

Any clues?

Regards,
