After removing the label from the namespace or removing ACRQ from cluster PODs continue to stay in the SchedulingGated state until at least one of the VMs is restarted:

# ACRQ with label selector and quota pods=1
  total:
    hard:
      pods: "1"
    used:
      pods: "1"

# One VM is running, other PODs in gated state

1. create acrq with label selector and pods quota
2. create namespace with this label
3. create multiple VMs and check virt-launcher pods are in SchedulingGated state
4. remove label from namespace (or delete ACRQ)

PODs remain in SchedulingGated state

PODs should run as soon as quota removed
