AFAIK it just contains unstripped binaries, so you can use 'gdb' to debug it.
(You might have to run /usr/lib/debug/usr/bin/kvm (or qemu-*) instead of the
regular binary, but I don't think that's necessary, I'm not sure though right
To see the source line contents in backtraces the source files have to be
(You can add a path to the source tree with the `dir` command from within qemu
you've built the package in a temporary location and deleted the files already.
Note that the files must be exactly the same you compiled from otherwise the
will just be wrong.)
It'll only allow you to debug the qemu related parts though, eg. if the VM dies
error inside the guest itself (kernel segfault or whatever), then that's not
an error in the host qemu process, so you won't get the chance to do a backtrace
if the guest kernel segfaults because qemu then exits successfully...
