Hyper-V guest kernel debugging problem

Hi everyone,

I’ve setup my box as described in this post: http://www.osronline.com/showThread.CFM?link=234398 (11th message by Jake Oshins).

Guest OS:
C:\Windows\system32>bcdedit /dbgsettings
key *.*.*.*.*
debugtype NET
hostip 10.0.0.3
port 50000
dhcp Yes
The operation completed successfully.

Hypervisor was configured via
.\synthdebug.ps1 -vmname Win8Test -port 50000

And I start windbg using windbg -k net:port=50000,target=MyHostOSComputerName,key=my.key.X.X

I aslo added incoming rule for UDP 50000 to host firewall.

Now in windbg I can’t get past “Waiting to reconnect…”

When I start VM after starting windbg, it fails to start, because (I guess) port on Host OS is occupied by windbg. I tried to use .\synthdebug.ps1 -vmname Win8Test -autoassign, but still nothing happens and windbg does not display anything post “Waiting to reconnect…”

What do I need to do to fix it? Should I assign random port to in Hyper-V command, and add a rule for it in firewall also?
