[Xen-users] Problem running i386 client under amd64 dom0
I''m running on a Dell PowerEdge 2970 with two dual core Opteron
processors, on which I have installed Debian Etch for x86_64 (amd64).
I''m using xen 3.1.0, which I compiled from a source tarball downloaded
from www.xensource.com, and which seems to have been created on May 18.
The kernel which this creates works, but I have a difficulty getting
certain other software working with it, so I am instead using Debian''s
own linux-image-2.6.18-4-xen-amd64, version 2.6.18.dfsg.1-12etch2,
which does not have this problem. I can easily create a virtual
host using the same kernel and using Debian etch as well.
My problem is that I can''t start up a domain using a 32-bit
kernel, for example, Debian''s linux-image-2.6.18-4-xen-686 version
2.6.18.dfsg.1-12. When I try this, the domain creation fails. The
Xend.log has the message:
[2007-07-11 08:30:52 3061] WARNING (__init__:1072) Domain has crashed:
and the console of the domain contains a long series of messages,
beginning and ending thus:
BUG: unable to handle kernel paging request at virtual address 98b7dce8
...
<0>Kernel panic - not syncing: Fatal exception in interrupt
Isn''t xen 3.1 able to run mixed architecture domUs? Do we need a
special option in the config file to do this?

Re: [Xen-users] Problem running i386 client under amd64 dom0
-----BEGIN PGP SIGNED MESSAGE----- Hash: SHA1 I''ve got 32 bit HVMs and a 32 bit PV domU running under a Xen 3.1 hypervisor. I did have some trouble with the PV one though, although I can''t remember if I was getting the same error that you are. At any rate, my problem was solved by using a kernel compiled against Xen 3.1. This was the only was I could get it running. What version of Xen was this Debian kernel compiled with? If it''s pre 3.1, have you tried using a kernel from the Xen site as this domU''s kernel?
