hypervisor showing cpu used and 16 instances
Issue
-
We cant instantiate any new VM'S
-
Can you help us with this urgent case, the hypervisor is showing used resources even though they have all been evacuated.
-
overcloud-compue-0
has no instances running but is showing that it is consumed in the hypervisor info.
(overcloud) [stack@undercloud ~]$ openstack hypervisor show overcloud-compute-0
