I tried to debug xen use kdb. After compiling xen with debug=y, is there any further steps I should take? I can get console outputs start with:        Xen 4.4.1        (XEN) Xen version 4.4.1 (root@) (gcc (Ubuntu 4.8.4-2ubuntu1~14.04) 4.8.4) debug=y Wed Dec 16 11:01:14        .....But I can't step into the boot procedure.  The kdb seems not built in and there is no kdb folder in /tools/debugger. How can I build xen-4.4.1/xen-4.4.6 with kdb?

The version embedded with kdb only updates to 4.1.0. How can I use it with xen 4.6?  Or is there any other debuggers which can step in Xen?

Hey!
If I recall correctly, I did try to port kdb. Let me find out what
happened there.

Hey

I did look into this and I could not find the trace of what I have
done before. So I decided to ytu and port it to current version from
this Mukesh patch:
http://lists.xen.org/archives/html/xen-devel/2014-04/msg00003.html
It looks like it applied without major issues, but I have not tested
it yet, but its in my plan for next week.

Hi, Elena. I tried to patch xen-4.4.1 with the patches at http://lists.xen.org/archives/html/xen-devel/2014-04/msg00003.html. However, after the patching, when I make with kdb=y, it would interrupt for error: 'struct domain' has no member named 'is_paused_by_controller'. Does the patch really work with xen-4.4?

Besides of that, even when I compile the debuggers.hg version of xen-4.1.0 at http://xenbits.xensource.com/ext/debuggers.hg, it will interrupt for:
