netbsd as a non-domain0 os : init problem

[Thomas Riboulet <ange%librium.org@localhost>]

hi,


I'm having an error when starting netbsd as a domainU os in xen 2.
The error has already appear in this list but I wasn't able to make it 
work with all the info in the archive.

the error :
"init: copying out path `/sbin/init' 11"

and then hang out



the context :
dom0 os : linux 2.6.10

os : Ubuntu GNU/Linux

more :
attached boot messages and config file


more :

I've tried to rebuild the kernel without the "options NTP" and with 
"options HZ=50", still got the error.

Then I've tried to boot on the kernels builded by Manuel Bouyer there : 
ftp://asim.lip6.fr/outgoing/bouyer/

the netbsd-XENU-INSTALL boot and launch the install process but I can't 
do anything more because it doesn't find any disk.
the netbsd-XENU kernel got the same error (copying out path ...)

so I've tried to build my own using the Manuel Bouyer cvs branch and I 
got the same error.


So : I'm thinking that the kernel isn't the problem and that it might 
come from the config file and more precisely the disks. I'm using ext2 
formated diskfiles. I've extracted the base and etc i386 sets in the 
root diskfile, also tried with xen-i386 sets from xen website.


question : any idea of what's the problem ? is it because I'm using 
diskfiles and not partitions ? or is it a kernel problem ?

# Example Python setup script for 'xm create'.
# This script sets the parameters used when a domain is created using 'xm 
create'.
#
# This is a relatively advanced script that uses a parameter, vmid, to control
# the settings. So this script can be used to start a set of domains by
# setting the vmid parameter on the 'xm create' command line. For example:
#
# xm create vmid=1
# xm create vmid=2
# xm create vmid=3
#
# The vmid is purely a script variable, and has no effect on the the domain
# id assigned to the new domain.
#============================================================================

# Define script variables here.
# xm_vars is defined automatically, use xm_vars.var() to define a variable.

# This function checks that 'vmid' has been given a valid value.
# It is called automatically by 'xm create'.
