On August 24th, a bugfix was merged into the hypershift repo to address OCPBUGS-16813 (https://github.com/openshift/hypershift/pull/2942). This resulted in a change in the konnectivity server with the HCP namespace. The change is that we went from a single konnectivity server to multiple when HA hcps are in use.
The konnectivity agents within the HCP worker nodes connect to the server through a route. When connecting through this route, the agents on the worker are supposed to discover all the HA konnectivity servers through round robin load balancing, meaning if the agents try to connect to the route endpoint enough times, the theory is that they should eventually discover all the servers.
With the kubevirt platform, only a single konnectivity server is discovered by the agents in the worker nodes, which leads to the inability for the kas on the HCP to reliably contact kubelets within the worker nodes.
The outcome of this issue is that webhooks (and other connections that require the kas (api server) in the HCP to contact worker nodes) to fail the majority of the time.
