Hi,
I would like feedback on a new proposal VEP 207: dynamic GuestAgentPing probe control - https://github.com/kubevirt/enhancements/pull/208.
It lets administrators temporarily silence GuestAgentPing probes on a running VM by simply adding an annotation to the VMI — useful during live migrations, backups, or OS updates where the guest is briefly unresponsive and you don't want Kubernetes restarting the Pod unnecessarily. The implementation is intentionally minimal: it reuses the existing gRPC channel between virt-handler and virt-launcher, requires no new Kubernetes resources, and is fully backward compatible.
Thanks
Karel
