Hello spacewalkers, recently I started discovering the spacewalk virtualization mechanism (rhnVirtualization.py, poller.py etc.) and there is a couple of things that aren't entirely clear to me. I'm sure some of them must have been thought through by the spacewalk team in the past and can be answered in seconds :) I'd be grateful for any help here.
1, No cleaning of the virtual machines that are no more reported by the poller: Currently the code flags non-existent machines as 'stopped'. This can fill the 'rhnVirtualInstance' table pretty quickly with "dead" virtual guest instances in the stopped state. The comment in 'poll_state' method in 'poller.py' explains there is no such thing as 'stopped' state. But libvirt can list out the stopped (aka 'defined') persistent domains [1]. Is there some reason why the automatic cleanup of such domains could not be implemented in the backend? (Softer solution would be to introduce a new state (e.g. 'deleted') and flag the dead virtual instances with it in case they aren't reported anymore. This would at least enable easier clean-up of them (basically something similar we do for inactive systems). I wonder if there is some fundamental problem that would prevent implementing this... I believe this should be pretty safe, do you agree?). 2, Purpose of the system.deleteGuestProfiles API endpoint: Apparently it serves for deleting unregistered guest virtual instances. IIUC this could be related to my previous question - it could serve for cleaning dead guest virtual instances, but this is just my speculation. Our traces lead to RFE [2] which is a clone of a private RFE [3]. Could you please take a quick peek and clarify this one? What was the reason for implementing it? Any help is appreciated. Thanks!
