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)

        (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)))
        )
    )
)
