I tried that, but it just dumps the domain config in SXP format, and 
then stops (see below).

I must have a "NOLUCK" flag :-) we tried Xen on two different P4 boxes, 
on two different Celeron boxes, and we had different problems each time. 
Would some bootflags be of any use ? Do some chipsets have a bad 
reputation, or something like that ?
Here's what happens when I attempt a restore :

isnpro:~# xm restore xipetotec.xen -c
(domain
   (id 24)
   (name xipetotec)
   (memory 0)
   (maxmem 65536)

   (console
       (status closed)
       (id 58)
       (domain 24)
       (local_port 0)
       (remote_port 0)
       (console_port 9624)
   )
   (devices)
   (config
       (vm
           (name xipetotec)
           (memory 64)
           (restart onreboot)
           (image
               (linux (kernel /boot/vmlinuz-2.6.9-xenU) (root 
'/dev/hda1 ro'))
           )
           (device (vbd (uname phy:isnpro/xipetotec-root) (dev hda1) 
(mode w)))
           (device (vif (mac aa:00:00:00:00:09) (bridge xen-br0)))
       )
   )
)
