Hi Adam,
Thanks for the detailed explanation.
You found two bugs :) -
1. The Less-broken scenario is a bug in edit VM Command, we added
support for hot plug disk lately, and the bug that you found is that
when attaching CD via edit VM command it is added unplugged.
https://bugzilla.redhat.com/show_bug.cgi?id=807922
2. The broken scenario is a bug in create VM and is related to the
stable device addresses feature we also added not so long ago and are
still trying to stabilize. The CD path is added in the VM static table
but no device is created in the VM device list (although it should).
https://bugzilla.redhat.com/show_bug.cgi?id=807923
I added you to the CC list of the bugs I opened (following your report),
I hope we'll have the fixes ready soon.
Thank, Livnat
