I unpack the XS5.6 source code "linux-2.6.27.42-0.1.1.xs5.6.0.44.111158".
In "linux-2.6.27.42-0.1.1.xs5.6.0.44.111158/arch/x86/Kconfig.debug"

config KDB
	bool "Built-in Kernel Debugger support"
	depends on DEBUG_KERNEL && !XEN

Why disable XEN? I should use unstable kernel to debug? How to get it? 
Any suggestion is appreciated. 

Thanks!
