hi, Dustin
My real, original,  problem was trying to get rid of the domain that 
failed to install, so I could have another go. I was unable to find what 
the error message means - see the subject line.

The errors in the second post arose while I was trying to work around 
the original problem. They look to me like errors in the shell script; 
they could be symptoms of the original problem, but they're not it.

There is currently nothing in /var/lib/xen/save.


The timeout is set in /etc/xen/scripts/locking.sh. I don't understand 
what it does, but it seems to me it doesn't do what's wanted. The 
"unknown" in this message seems to arise because the lock's not held:
Nov  6 12:49:29 potoroo logger: /etc/xen/scripts/vtpm-delete: Forced to 
steal lock on /var/run/xen-hotplug/vtpmdb from unknown!

Judging from the number of the messages and their frequency, the script 
is looping.
