Xen devel - Feb 2008 - OSError: [Errno 10] No child processes

Hi;

After updating our Xen packages to current tip of xen-3.1-testing (from 3.1.0)

caglar@zangetsu xen-3.1-testing.hg $ hg tip
changeset:   15634:dbe47d8cb825
tag:         tip
user:        Keir Fraser <keir.fraser@citrix.com>
date:        Thu Jan 31 10:07:57 2008 +0000
summary:     Added tag RELEASE-3.1.3 for changeset
4835d702ba6133849bfae64b783b755c5066c094

I cannot boot domU''s anymore and i also cannot see what''s the
problem from logs

After a "xend start" trying to start ttylinux with following config

caglar@zangetsu ~ $ cat /etc/xen/ttylinux
kernel = "/boot/kernel-2.6.18.8-16-domU"
ramdisk = "/boot/initramfs-2.6.18.8-16-domU"
memory = 64
name = "ttylinux"
disk = ["file:/home/caglar/ttylinux,sda1,w"]
root = "/dev/sda1 ro"

ends up like following

zangetsu ~ # xm create -c /etc/xen/ttylinux
Using config file "/etc/xen/ttylinux".
Started domain ttylinux
Unexpected error: exceptions.OSError

OSError: [Errno 10] No child processes

adding on_crash="preserve" to domU''s config and trying to
attach it also fails seems Domain crashed before booting.

Full logs can be found at http://cekirdek.pardus.org.tr/~caglar/xen/

Any help/advice/tip really appreciated.

Cheers

Please discard this mail, i finally found the problem (one of our distro
specific kernel patches causes that problem) and further testing yields vanilla
xen-3.1-testing works without a problem.
