[Xen-devel] how to debug xen

[holmes <albert.holmes@xxxxxxx>]

Hi all,

I am new to Xen. I want to debug xen. So I have few questions here. If anybody can help me, I'd appreciate it.

1: My system is ubuntu 8.04. I download the xen-3.4.2 source code from xen website. After I "make world", it will download the linux-2.6.18-xen.hg (kernel?).  Also it will make many other folders (./dist). I found blkfront.c in both ./linux-2.6.18-xen.hg/drivers/xen/blkfront folder and ./dist/install/lib/modules/2.6.18.8-xen/source/drivers/xen/blkfront/ folder. So, what's the difference of the two folders and what are they doing?

2: if I want to log the activities (read/write block) information in domU(winxp), how do I log it? For example, if domU read a block, I therefore print a information into a log file (like "domU read"). Should I change something in blkfront.c file? If so, which one should I change, because there are two blkfront.c.

3: if I want to log the information, I GUESS (not sure) I should use log.debug (or else) to log the info. into some log files. How should I do? Can anyone give me suggestion?

 

Thanks!!
