well, wasn't going to make this an issue -- as I'm not yet committed
to Xen 4 (*suse's flavor, anyway) until it's a bit more widely-used &
stable, but -- since you asked,

zypper dup -r XEN4
cp /etc/xend-config.sxp.XEN4 /etc/xend-config.sxp
reboot

uname -rp
  2.6.31.8-0.1-xen x86_64

xm create -c /home/xen/vm/test.cfg
  Using config file "/home/xen/vm/test.cfg".
  Error: Domain 'test' does not exist.

xend log -> http://pastebin.com/d6c5d3100.  if something 'in there' is
informative, hth!

drop back to xen3x, all's OK again.

directly there.  after reboot, @
