Re: [Xen-users] Unsticking a DomU

Sorry for the long absence, Stephan:

The DomU's are still stuck (i.e., they can't be started, destroyed, or deleted) and I've pasted the configuration below:

=================================

I just want to delete these stubborn DomU's and start over.

Ideas? Suggestions?

Could you post the configurations for test1, test3 and test4, please ?

Additionally, can you verify the misbehaviour of test3 if you didn't
start test1 before?

Cheers,

- Stephan

There's also a debug log and corresponding qemu-dm logs if the
configured device_model is qemu-dm.
