Windows 10 Kernel Debugging on Xen

[Neil Sikka <neilsikka@xxxxxxxxx>]

Hello,

Has anyone gotten a Windows10 (Version 1709 of later) kernel debugger attached when running the Windows10 debugger VM and the Windows10 debugee VM on Xen 4.13.0 hypervisor? I am getting a "NIC hardware initialization failed" error. I tried the suggestions in the discussion here (https://bugzilla.redhat.com/show_bug.cgi?id=1947015):
-cpu Skylake-Server-IBRS,ss=on,vmx=on,hypervisor=on,tsc-adjust=on,clflushopt=on,umip=on,pku=on,md-clear=on,stibp=on,arch-capabilities=on,ssbd=on,xsaves=on,ibpb=on,amd-ssbd=on, \
skip-l1dfl-vmentry=on,mpx=off,hv-time,hv-relaxed,hv-vapic,hv-spinlocks=0x1fff,hv-vendor-id=KVMKVMKVM

note: i had to remove the following 2 arguments due to errors from QEMU:
pschange-mc-no=on
hv_vpindex

Here was the error:
C:\Users\user\Desktop\oldDebuggers\x64>kdnet.exe

Network debugging is supported on the following NICs:
busparams=0.4.0, Intel(R) PRO/1000 MT Network Connection, Plugged in.
The Microsoft hypervisor running this VM does not support KDNET.
Please upgrade to the hypervisor shipped in Windows 8 or WS2012 or later.

KDNET initialization failed.  Status = 0xC0000182.
NIC hardware initialization failed.

I am using an Intel e1000 NIC emulated through QEMU because its supposedly a supported NIC for Windows kernel NET debugging.

Thanks in Advance!
