[Xen-users] Xen on Dell PowerEdge 2500 - Crashes after 0.1 seconds, no visible errors

[Allen Brooker <allen@xxxxxxxxxxxxx>]

Hi all,

I'm having an annoying problem with Xen on a Dell PowerEdge 2500 (with
disks configured for hardware RAID striping). Basically the dom0 starts
and runs fine. I've also tried the Xen LiveCD 1.5 and that can boot
debian dom0 and boot a debian domU perfectly fine. However, I just can't
get a domU to start from my install. I've tried all the versions of xen
from 3.0.2 up that I can get my hands on to no avail.

What happens is this: domU appears to start up, but never appears to
attach to the console. If I stick the domU on preserve mode, I can see
that the domU reportedly runs for 0.1 seconds before crashing. I cannot
find any errors or messages anywhere to indicate why the domU crashes. I
appear to get no output from the domU itself at all.

Below is the contents of /var/log/xend.log for the creation (and crash
and destruction) of the domU.

Is there anyone running Xen on a Dell PowerEdge 2500 that might be able
to send me their host and domU kernel configs?

I did have Xen running perfectly on a previous machine (which
unfortunately died of an unknown hardware problem) and I've tried
copying the kernel configs from that and using those with only the
necessary modifications for the hardware of the new machine, all to no
avail.

I also asked about this problem on #xen on OFTC and ##xen on Freenode
for a week solid without any progress. If you want to talk to me, I can
usually be found there (I'm a lazy bum of a university student, so I'm
on most of the time during the British daytime).

I can't think of any further information that might be useful at the
moment - If you want to know something, just ask.

Thanks in advance,

AllenJB
