Hi All, I'm trying to make sense of 'nova-manage service describe_resource' output from Folsom running on Ubuntu 12.04 with KVM back end.
I'd thought used_now accounted for running resource use and used_max included reservations that had not yet been instantiated. That assumption seemed to match what I saw under Essex. now I have situations like this: HOST PROJECT cpu mem(mb) hdd nova-3 (total) 24 48295 605 nova-3 (used_now) 140 287232 3400 nova-3 (used_max) 4 8192 90 nova-3 956ae20bbb444a8c8f149729198aec63 4 8192 90 where "used_now" is wildly higher than it seems it should be. looking on the compute node itself verifies there are 4 single vCPU instances running there. On a different system reporting a high "used_now" but zero actually running instances I tried rebooting the compute node hoping to clear state (since the node pushes these numbers to the database correcting them there doesn't work). On reboot it came up claiming over 160 cpus in use. Is this a bug, a misconfiguration, or a misunderstanging? Thanks, -Jon
