I've verified that udevd is there and is running:
#c5xen# /etc/xen> ps -ef | grep udevd
root      2772     1  0 20:33 ?        00:00:00 udevd

All xen scripts are in correct place except there is no xen related
files in rules.d. However I checked your install scripts and find statements
like this:

if [ -x /sbin/udev ] && [ ! -z `udev -V` ] && [ `/sbin/udev -V` -ge 059 ];
then
  cp -f $src/etc/udev/rules.d/*.rules $dst/etc/udev/rules.d/
else
  cp -f $src/etc/hotplug/*.agent $dst/etc/hotplug/
fi

The udev -V command outputs nothing on my system. And udevinfo -V
outputs 039. So I believe the else
branch gets executed. And I check that xen-backend.agent is there in
/etc/hotplug. Is this the problem? Do I have to install a newer version of
udev to make the whole thing work?

I tried manually copy your xen-backend.rules to rules.d but it doesn't
seem to help.

And I find entry like this in /var/log/messages after xm create fails:

This is the only problem I can find. Would you please give more
suggestions?

Thank you very much!
