Hyper-V Kernel Debugging

NTDEV

From what I can tell there is no serial port emulation involved. I appears that the guys on the Hyper-V team installed hooks to allow for network emulation of some kind in conjunction with WMI, from what I have seen the speed is more like 1394 or faster.

The emulated serial port transport is not particularly fast. All of the other transports are significantly higher performance, including in Hyper-V.

Then emulated serial port? it is amazingly fast.

That means that i can’t use net debug thru Hyper-V feature because I am not able to set ports to use, using Hyper-V WMI interface? Or not?

Not if you are using a host older than when the network debugging feature was invented, no.
