Comment 2 Ofir Nash 2021-07-15 11:57:48 UTC

Verified on version: cluster-network-addons-operator version is: v2.5.7-1

Scenario Checked:

1. Created 1000 basic VMs (https://github.com/kubevirt/kubevirt/blob/master/examples/vm-cirros.yaml).
2. Checked KubeMacPool pods are still running and didn't crash/get killed after some time.

(Attached script used to create the VM's).
