Unable to single-step in kvm, always results in a resume

Hi All,

I am trying to single-step through my kernel using qemu and kvm. I have
run qemu via:
qemu-system-x86_64 -s -S -hda /home/nickamon/lab1/obj/kernel.img and
also connected to the process using gdb.

Problem is that whenever I try and step instruction, it seems to resume
my kernel rather than allowing me to progress instruction by
instruction. I have built the kvm snapshot from git and still no luck.
Tried following the code for a few hours and have no luck. Any suggestions?

Thanks,

Nicholas
