kubevirt - Waiting for kube-control relation

[Pedro Victor Lourenço Fragola]

Using the ck8s 1.24/stable and kubevirt edge/rev-3 the environment is not able to finish the kubevirt deployment

Status:

kubevirt - Waiting for kube-control relation

Juju logs:

unit-kubevirt-1: 18:28:59 ERROR unit.kubevirt/1.juju-log kube-control:31: kube-control relation data not yet valid. (1 validation error for Data
registry-location
  field required (type=value_error.missing)
unit-kubevirt-1: 18:28:59 INFO juju.worker.uniter.operation ran "kube-control-relation-changed" hook (via hook dispatching script: dispatch)
unit-kubevirt-1: 18:29:33 INFO juju.worker.uniter.operation ran "update-status" hook (via hook dispatching script: dispatch)
unit-kubevirt-1: 18:30:41 ERROR unit.kubevirt/1.juju-log kube-control:31: kube-control relation data not yet valid. (1 validation error for Data
registry-location

As per the log[0] kubevirt is not showing registry-location.

Workaround:

Force to re-set the registry-location:

juju config kubernetes-control-plane image-registry=rocks.canonical.com:443/cdk/temp

Wait to finish the configuration and set it again:

juju config kubernetes-control-plane --reset image-registry

Now it is showing the registry:

          registry-location: rocks.canonical.com:443/cdk

the `registry-location` field was missing in the `kube-control` relation from the 1.24/stable kubernetes-control-plane charm. Looking over that charm (as well as 1.25 and 1.26 releases) it may be possible to get this bug to occur again by deploying charmed kubernetes until it's completely active/idle.

Next, one would then deploy and relate the kubevirt charm with all its necessary relations. This may create the kube-control relation in such a way that the registry-location isn't provided.

Doesn't address the original issue in 1.24/stable, but does however address another install issue found while debugging this bug
