Subject: Debugging Xen via serial console
Date: Wed, 28 Jan 2009 13:53:57 -0500	[thread overview]
Message-ID: <4980A9C5.9040303@ncsu.edu> (raw)

I'm trying to debug Xen remotely using serial port.  I followed the 
instructions on the following post made in this xen-devel list:
http://lists.xensource.com/archives/html/xen-devel/2007-12/msg00678.html

I was able to connect gdb but I ran into a problem where even after I 
clear all the breakpoints, execution traps into gdb with SIGTRAP at 
restore_all_xen().  This only happens if I set a breakpoint and then try 
to continue after hitting the break point.  If I simply connect gdb but 
continue without setting any breakpoints, everything is OK.

The post mentions some stability issues and I haven't seen any follow 
ups.  Is this still a viable debugging method?  Or is there some other 
method I should try?

Thanks in advance,

John
