Thread-topic:	HVM Debugging (Injecting INT3)

I am debugging a driver inside a HVM and I'll want to trigger a debug break from the device model if the guest access a specific PCI config address.

I thought about creating a hypercall that injects TRAP_int3 using vmx_inject_hw_exception()/svm_inject_exception().

If I'll place the correct hook in ioemu, is it simple as creating a hypercall that calls vmx_inject_hw_exception() in order to break on the actual instruction that performs the PCI config access?

Thanks,

Guy.
