Modern (11/2022) Windows Kernel Debug on Proxmox:
- I couldn't get NET to work so far, neither with virtio nor e1000 vNIC's
- Windows 11 refuses to recognize serial ports too, even with virtio drivers. It'd have been royal to use WinDbg from Store but :(
- Windows Server 2022 does recognize COM ports (maybe drivers can be transplanted to 11?)
- COM ports can be connected from the Proxmox host using socat as described here:
