[BitVisor-devel-en:63] debugging methods for BitVisor and a question about panic

[vmm learner]

Hi, I am doing some research on monitoring the kernel by BitVisor. During my studying, I encountered some problems  on debugging the BitVisor. 1. Using the panic function to print some log messages to trace and debug  is my original idea. I found when I called the panic function( vmm.shell has been set to 1), the computer went to dead and nothing was printed on the screen. However, I also found that the panic function worked well during the  period of start-up. I don't know why.2. [bitvisor-devel-en:25] and [bitvisor-devel-en:27] talked about the debugging method for BitVisor roughly, I want to know more details about it , such as how to debug BitVisor by using VMWare or QEMU and so on. Thanks for help very much！David.
