Let's see: * we need serial device for catching serial output on the host from the guest kernel * KGDB - I guess this was meant to jump into the debugger when the guest crashes or so, we could drop it. * DEBUG_KERNEL is also good for testing kernels * 9p is needed for -virtfs folder sharing, AFAICT: http://wiki.qemu.org/Documentation/9psetup So, I guess we can have another KVM_GUEST_KERNEL_TESTING option which enables those additional, good for debugging options (except 9p - it should be in the main thing) and which depends on KVM_GUEST. It would also contain other DEBUG_* stuff. Thanks. -- Regards/Gruss, Boris. Sent from a fat crate under my desk.
