Description of problem:
Distribution of 1000's of VMs over 9 nodes leaves 1 node empty
Version-Release number of selected component (if applicable):
OCP 4.16.30 CNV 4.16.6
How reproducible:
Unknown, can reproduce on current cluster.
Steps to Reproduce:
1. Allocate 9 nodes for VMs 2. Create 1000's of running VMs (increase allowed pod-per-node count as necessary) 3. Stop all VMs and subsequently restart them if result not immediately achieved
Actual results:
1 node receives no VMs
Expected results:
Relatively fair distribution between all 9 nodes
Additional info:
Confirmed the node can run the VMs by cordoning other 8 nodes. Behaves the same with or without defaultCPUModel set. Confirmed multiple matching CPU models between the nodes. On this cluster, the 1 node is always the same node.
