[Xen-users] Unable to launch DomU

[Eric Smith <esmithbss@xxxxxxxxxxxxx>]

HELP!!!!

(I have provided everything I can think of in this
email in the hopes that someone can help me a.s.a.p.)

I have followed the howtos at howtoforge.com to the
letter.  I have gone through the wiki's.  I have gone
through the mailing lists and I am still stuck.

I am trying to get Xen 3.0.2-2 running on kubuntu 6.06
(Dapper Drake).  My computer is a notebook with a
Pentium-M 750 (1.8GHz), 1GB ram, 80GB hd, ATI x600
video.

I have tried both the binary install and the source
install.  I even tried completely rebuilding my box
from scratch with FC5 and the xen 3.0.2 that comes
with the install DVD, but regardless of how I install
Xen, even though the Dom0 environment works great, I
cannot get a DomU environment to launch properly.

On both FC5 and kubuntu, every time I issue the xm
create call, the result is :

Using config file "polydactes-fw".
Started domain polydactes-fw
Linux version 2.6.16-xen (root@polydactes) (gcc
version 4.0.3 (Ubuntu 4.0.3-1ubuntu5)) #2 SMP Fri Jun

BIOS-provided physical RAM map:

Checking if this processor honours the WP bit even in
supervisor mode... Ok.


Then everything appears to lock up without going any
further.

If I look at "xm top", I can see that the DomU
environment is getting between 85% and 95% of the CPU,
but it apparently isn't going any further.  It's just
in some sort of infinite loop.

The config file for my DomU is simple (as shown in the
how-tos at howtoforge.com.  Here it is:

#  -*- mode: python; -*-
name="polydactes-fw"
kernel="/boot/vmlinuz-2.6-xen"
ramdisk="/boot/initrd-2.6-xen.img"

Looking at the xend-debug log file I see the

I know I'm missing something simple and stupid, but I
have absolutely no clue what the DomU is trying to do
at this point that would cause it to behave like this.

What do I need to do to correct this?

Sincerely,

Eric
