Thanks for the feedback.

Thanks,

+1 for me. And I am willing to be a volunteer.

Hello everyone, 

I have been recently working on a migration bug in nova (Bug #1233184). 

I noticed that compute service remains available, even if a connection to libvirt is broken. 
I thought that it might be better to disable the service (using conductor.manager.update_service()) and resume it once it's connected again. 
(maybe keep the host_stats periodic task running or create a dedicated one, once it succeed, the service will become available again). 
This way new vms wont be scheduled nor migrated to the disconnected host. 

Any thoughts on that? 

Sounds reasonable to me. If we can't reach libvirt there isn't much that nova-compute can / should do. 


Is anyone already working on that? 

Thank you, 
Vladik
