Hi,
I'm trying to set a hardware breakpoint inside the guest using gdb. This
doesn't seem to work. Execution just skips right over it. I've have also
tried writing some code to set a breakpoint by directly accessing the db
registers from the guest. This also did not cause a breakpoint to be
generated in the guest. Is it possible to use hardware breakpoints
inside the guest? Is there some configuration that must be set in qemu
or in the kvm modules?
The guest vm is running linux 2.6.18.
I'm using kvm-77 with linux kernel 2.6.27. I used the kvm kernel modules
that came with the linux kernel and not from kvm-77. I have an x86
machine. The command I use to run the vm is the following:
../kvm/qemu-system-x86_64 main.img -m 512 -vnc :0
Thanks,
Michael Le
