Re: [Fedora-xen] What is XendInvalidDomain?

John,
	I don't remember for sure, but it kinda looks to me like xendomains
(service to start and stop xen domains) is performing a shutdown instead of
a save.  If that is true, then the terminated could be a successful shutdown
or a timeout while waiting for shutdown (at which point the domain is
destroyed).  In either case, your restore failures would be because of bad
files in /var/lib/xen/save (or something like that) from a previous failed
save.  Deleting those files would get rid of your restore errors and the
domains would start normally when xendomains started back up (as they
presumably do now).  This timeout during xendomains shutdown is configurable
(even to forever), but I don't remember where.  What to do on xendomains
shutdown (save or shutdown) is also configurable (likely in the same file,
search for a xendomains.conf?).

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.

Have I offended folk?
Does nobody know?
Can't someone even tell me (nicely) where to go?
I read the initial report, but there wasn't really enough information to help. Restart the machine and tell us what operation(s) fails, with what error messages, and what you were expecting it to do.

I was trying to find what the message actually means, I think my chances of solving the underlying problem are quite good, once I know what it's talking about.


The problem arose when my install of ClarkConnect failed (it reckoned it needed more disk space than I offered), and I tried various ways to "undefine" it. virt-install doesn't recognise a failed install, so it figured it should boot the crook virtual disk.

I now have a working CC (I had to explicitly delete the disk image, virt-install doesn't resize it), and am having dismal results with Fedora 7:-(
