RE: [Xen-devel] can't start domains

the output i sent yesterday was a combination of xend and xm, here's just the xm output:

xen2:/etc/xen# xm create -f /etc/xen/gaia2
Using config file "/etc/xen/gaia2".
Error: Error creating domain: int argument required

here's /etc/xen/gaia2

# -*- mode: python; -*-

#import sys
#import xenctl.ip
vmid=3

kernel = "/boot/vmlinuz-2.6.7-xenU"

memory = 128

name = "gaia2"

cpu = vmid

nics = 2

vif = [ 'mac=FE:FD:01:00:04:00,bridge=br0', 'mac=FE:FD:01:00:04:01,bridge=br1' ]

disk = [ 'phy:vg00/gaia2,sda1,w', 'phy:vg00/gaia2-swap,sda2,w' ]

root = "/dev/sda1 ro"

extra = " 4 VMID=%d " % vmid

restart = False

it is identical to the one that works on the other server, except that on this one I had to comment out the two include lines, as it couldn't find xenctl.ip, i don't think that is required anymore anyway is it? it's not in the example configs.

there must be something different between this new server and the other one... i just can't seem to figure out what though!!!

here's a more complete output from xend, i think i missed a bit in my last post:

config: (vm (name gaia2) (memory 128) (cpu 3) (image (linux (kernel /boot/vmlinuz-2.6.7-xenU) (root '/dev/sda1 ro') (args ' 4 VMID=3 '))) (device (vbd (uname phy:vg00/gaia2) (dev sda1) (mode w))) (device (vbd (uname phy:vg00/gaia2-swap) (dev sda2) (mode w))) (device (vif (mac FE:FD:01:00:04:00) (bridge br0))) (device (vif (mac FE:FD:01:00:04:01) (bridge br1))))

Subject: Re: [Xen-devel] can't start domains

Something is going wrong during the domain creation, and then
xend tries to clean up by destroying the stillborn
domain. Unfortunately, we then hit a xend bug while destroying
the domain's block device (perhaps because that was the original
problem?) and the traceback all refers to this bug which prevents
it from reporting back to xm what the original problem was.

I've cc'ed Mike so that he can take a look at the Xend bug. 

As regards the real error, take a close look at the sxp config
data that that xm sends to xend and check that it matches your
expected configuration. (see the config: output from xend).
