Hi all
I''ve taken the plunge and decided to set up Xen on my AMD64 machine. I
want to use amd64 debian as the domain 0 O/S, then install a full amd64
debian dev kit and a couple of 32-bit linuxes on top.
I''ve got an install of debian amd64 running as domain0, which boots up
just fine. I boot it with dom0_mem=131072 (the machine has 1Gb of RAM).
I then created some disk images for /, /home and swap using dd, and used
debootstrap --arch amd64 sarge /mnt
http://amd64.debian.net/debian-amd64/
to create a base install in the root image, once I had mounted it. I saw
a few errors come up in this about missing dependencies.
I chrooted /mnt and did the usual set of changes to /etc/fstab,
/etc/network/interfaces etc, then unmounted it.
My problem now is that I can never get the xm create command to work. My
config file (/etc/xen/linuxdev) looks like this:
name="linuxdev"
memory=512
kernel="/boot/vmlinuz-2.6-xenU"
nics=1
disk=] ''file:/srv/linuxdev.img,hda1,w'',
''file:/src/linuxdev_home.img,hda2,w'' ]
root="/dev/hda1 ro"
The kernel image file exists and is the -xenU equivalent of my -xen0
working domain0 image (both from the binary unstable dist).
Before I try xm create, xm list shows me:
Name Id Mem(MB) CPU VCPU(s) State Time(s)
Domain-0 0 123 0 1
r---- 18.3
When I do
xm create /etc/xen/linuxdev -c
I get:
Using config file "/etc/xen/linuxdev".
Error: Error creating domain: (0, ''Error'')
xm list now shows:
Name Id Mem(MB) CPU VCPU(s) State Time(s)
Domain-0 0 635 0 1
r---- 19.5
Note the memory increase in Domain-0. Each time I try xm create it goes
up until it runs out of memory.
Looking at /var/log/xend-debug.log, the last line says:
File
"/local/scratch/xenod/cron-build/xen-unstable-x86_64.ud6331.dir/xen-unstable.hg/dist/install/usr/lib64/python/xen/xend/image.py",
line 248, in buildDomain
error: (0, ''Error'').
I notice that line 248 of image.py on my system is a call to xc.linux_build.
Hopefully this is some really dumb xen newbie thing I''m doing wrong.
Can
anyone help?
Sorry for the size of the email; I wanted to include everything.
Simon

Sorry, I meant disk=[ ''file:/srv/linuxdev.img,hda1,w'', ''file:/srv/linuxdev_home.img,hda2,w'' ] It''s been a long day.

No, that was my clumsy typing :-/. The error occurs even with the correct line. And I think you''re right about tomorrow. Karsten M.
