how to do remote kernel degugging on Maverics 10.9 OSX using lldb?

Question

I am trying to do remote-kernel-debugging. I am using two VM. I have Leopard OSX 10.9 on both VMs and I also installed KDK(kernel debug kit as per the system version).

On the VMs to be debugged I have used the following instruction to start debugging.. $nvram boot-args="debug=0x141 kext-dev-mode=1 kcsuffix=development pmuflags=1 -v"

Now on VM to be debugged on restart I am getting - "Waiting for remote debugger connection.

And on other machine when i tried to connect with lldb - kdp-remote (ip) . It says KDP_REATTACH failed.

I dont know what is problem. Help needed !!

While remote kernel(MAC OSX) debugging make sure that your host machine must be physical one and target machine could be VM. Do not try to do remote debugging on two VMs.
