Public bug reported: issue: I have experienced multiple instances where windows VMS running on kvm froze. Some VMS occur once every one or two months. The symptoms include a black screen and no response from the console, the virtual cpu usage reaching 100%, and the virtual machine's network being inaccessible. The solution is to hard restart the virtual machine or perform a hot migration to another Host, which can immediately restore it. It is suspected to be a bug related to kvm or kernel. The guestvm log has been checked and no findings were found. Neither kvm nor kernel generates any special logs.
I find some similar issue from promox ,the solution is upgrade kernel to 6.8. https://forum.proxmox.com/threads/proxmox-8-0-kernel-6-2-x-100-cpu-issue-with-windows-server-2019-vms.130727/page-12
