[fedora-virt] Kernel Bug in Guests

[James Hubbard]

I'm getting errors dumped to console for guests.  The guests are
Centos 5.4 i386 and x86_64 guests running at the same time.  I've
configured each with 2048MB RAM and 2 processors.  One is set for i686
and the other for x86_64.  The host is a Phenon II X4 810 with 8GB of
RAM.   Both guests are running at the same time, but aren't doing much
of anything.

Kernel: 2.6.31.6-145.fc12.x86_64

Smolt Profile.
http://www.smolts.org/client/show/pub_b0b2aaa5-92b5-4cd5-9192-b8c63f92afe3

Does anyone have a suggestion?


Here's the output for x86_64 guest.
