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:

https://forum.proxmox.com/threads/two-windows-guests-communicating-via-serial-console-comn.67588/

- You should of course disable Secure Boot - you can do that in the VM's BIOS under Device Manager / Secure Boot Config / Attempt Secure Boot

TBC

@dey umm, what do you think I should look at here?

@buherator it shows a way to install kdnet maybe create a virtual commport in windows? See if proxmox sess it

@buherator the serialuser in the forum is you?

@dey no it's not me.

@dey problem is COM ports don't show up at all, independently from the debugger setup. kdnet NIC diagnostics seem useful though!

@dey OK it says "network debugging is supported" then lists no compatible NIC's :D
