I have two Windows servers (2012 & 2016), that are no longer responding to Shutdown calls to Guest Agent. The Qemu services are running on both and I have restarted them. I have checked that neither VM has a lock or anything pending (not even updates). What I have just noticed that both of the affected servers are not responding to the [qm guest agent <vmid> ping] commands. Other Windows servers on the same hosts are responding to the ping. Both of these servers were previously responding to the Shutdown calls. Any help is appreciated.
