Greetings,
I am trying to debug a Xen crash and need some
help. When I am attempting to use the (relatively) new adjust_global scheduler
callback function, the machine reboots (this may be due to other changes I have
made in the hypervisor to modify DornerWorks’ ARINC 653 scheduler to work
with CPU pools). I have enabled xend/xenstored tracing, but the log files
do not contain anything useful. I have used gdb to trace to the point
where the hypercall is made from Dom0 to the hypervisor, but do not know how to
proceed from here. I have read about using kdb to debug the hypervisor,
but I am a bit confused. It looks as though kdb (in http://xenbits.xensource.com/ext/debuggers.hg)
is integrated into a particular branch of Xen, which is not kept synchronized
with the current version of xen-unstable. Can I use kdb with any version
of Xen? If so, how? What files do I need to download and what
should I do to build them? Or does someone have other suggestions?
Thank you,
