Further update, when I try to create Suse9.2 domain by hand, about 1/3 of
the time it succeeds, the other 2/3 I get the following error on the
console:

VFS: Cannot open root device "hda1" or unknown-block(2,0)
Please append a correct "root=" boot option              
Kernel panic - not syncing: VFS: Unable to mount root fs on
unknown-block(2,0)

All the configuration is the same, I'm just running xm create -c
/etc/xen/auto/Suse9.2 over again each time it fails.

There is no silver bullet.  Plus, werewolves make better neighbors
than zombies, and they tend to keep the vampire population down.
