Hi Gene, thanks for the info. Please file bugs about any issues you hit so
they are at least tracked.

Can you give an example? Do you mean state changes or XML changes?

Agreed, any issues like that should be fixed ASAP and I'm willing to help.

These feature requests are good to track, but honestly they won't likely ever
get done unless someone steps up to work on them. I would be happy to review
patches, provide guidance, even help with the UI bits if someone started the
process.

As mentioned above, anything that's a bug and makes virt-manager crash or
complain should get fixed ASAP and I'm willing to help with that. Feature
additions will generally require someone else to push them.
