Red Hat Bugzilla – Bug 249094
virt-manager starts domU install even though error with duplicate name exists
Last modified: 2010-10-22 12:43:56 EDT
Description of problem:
In making and deleting a lot of domU instances, I've occasionally used a name
more than once. Even if it was previously deleted, virt-manager always gives an
error about the name being used before. It then proceeds to start the install
even though I go back and change the name. This is confusing to say the least.
Version-Release number of selected component (if applicable):
happens every time
Steps to Reproduce:

Hmm, good catch, thanks. This turns out to be a nasty python reference-counting
bug (we think). Working on a fix now.
The patch below fixes the problem by forcing libvirt to release the underlying
pointer to the domain object, even though the python code doesn't always release
the reference reliably.

Aggressively free domain pointer in libvirt
This patch aggressively frees the domain pointer in libvirt so that when you
create a domain with the same name as one you just deleted, the deleted domain
configuration doesn't get resurrected in virt-manager.
