问题
I want to kernel-debug my Hyper-V VMs. I can do it via COM port to pipe method (Ref), but that gives me throughput of 60-80 KBytes/sec, which is too slow for e.g. take dump files.
So, I'm trying to setup Synthetic kernel debugging for Hyper-V virtual machines, but Kernel debugger never connects.
Troubleshooting and details:
- I verified that the the worker process
vmwp.exelistens to UDP:55555 by runningnetstat -nao | findstr /C:"55555". - I tried to connect from another machine, and confirmed via wireshark that windbg on the other machine indeed sends packets to UDP:55555
- I've created a Windows Firewall rule allowing UDP:55555 from all IPs, bound to all profiles.
- My host and Guest OSs are Windows 10 v1703 64-bit.
