Jonathan -
gdbserver-xen is behaving as I expect, now that I've turned off
crash_debug in
Rules.mk. Thanks again for your helpful suggestions.
Indeed, I am interested in debugging domU. However, the domU kernel
I've built is crashing and / or xend is crashing before the domain can
even be started "paused".
Are you passing -p to "xm create"? If so, it is a xend problem, because
that will pause the OS before the *first instruction*. However, it
shouldn't be causing xend to crash until it gets to the xenbus init
code.
If I try to use gdbserver-xen to connect to one of my
invisible-to-xm-list domains, gdbserver-xen segfaults once gdb connects
to it. I believe this is interesting because gdbserver-xen will
complain about nonexistant domains if I pass it a domain id which has
never been used this boot cycle. If I pass it a domain which ran
successfully, but has shutdown, it says "getdomaininfo failed". Hence,
I believe the segfault of gdbserver-xen is directly related to the
changes I've made to the kernel I want to debug.
Could you send me the output from the two different runs? Odds are the segfault is easily fixable.
