Hi,

I am investigating the possibility of debugging guest kernel with KVM.
Anybody may shed some lights into how KVM handles breakpoints?

Suppose that we put a breakpoint (0xCC opcode in x86) into guest
kernel. When the kernel hits the breakpoint, which one will handle the
event?

Looks like qemu will handle the breakpoint first, then next the guest
kernel itself have a chance to process it. Is that correct?

And is there any chance for the host (VMM) to get notified about the event?

Thank you,
Jun
