Description Luis Tomas Bolivar 2019-11-26 14:29:24 UTC 
When kuryr-controller gets restarted, and before the pools are recovered, there is some pools repopulation events triggered due to handling events previous to the kuryr-controller restart. This leads to unneeded repopulation actions as well as delayed pools recovery
Comment 2 Jon Uriarte 2020-02-20 14:51:59 UTC 
Verified in 4.4.0-0.nightly-2020-02-17-131733 build on top of OSP 13 2020-01-15.3 puddle.

The OCP installer finishes successfully:

 $ oc get clusterversion
 NAME      VERSION                             AVAILABLE   PROGRESSING   SINCE   STATUS
 version   4.4.0-0.nightly-2020-02-17-131733   True        False         16h     Cluster version is 4.4.0-0.nightly-2020-02-17-131733

While running kubernetes/conformance test from origin the release-4.4 kuryr-controller pod showed next message:
"Kuryr-controller not yet ready to populate pools" and raised kuryr_kubernetes.exceptions.ResourceNotReady exception.
