Thanks for your reply.

I should use this version(4.5) because I received a solution developed in the version.

@Roger Pau Monné

Firstly, Thank you for your reply.

I also considered the option using serial cable but, I think if I can get debugging information with only SW method(crashdump), that method will be more flexible way to debug on Xen.

Even if I have struggled to find the way to debug Xen using crashdump, I failed. So, finally I ordered serial cable.

My suggestion would be to get the output from the serial port
instead, specially if you plan to do Xen development. It's going to be
much more reliable.
