Comment 1 Petr Horáček 2021-06-03 12:03:30 UTC

Changing the release version. Note that it will be released on the same date as was originally targeted for 2.6.4

Comment 2 Ofir Nash 2021-07-14 08:25:25 UTC

Verified on version: cluster-network-addons-operator version is: v2.6.6-2

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).
