Odd that it would suggest VirtualBox when kvm-based VMs are native to the kernel. I’d use virsh to do the same thing, with fewer moving parts. > I am intereseted in debugging a new kernel module which I will write > (v4l pci express module) It sounds like you’re going to be debugging a kernel module for physical hardware? That makes a lot of the above URL useless — you want to use kdbg from a serial console attached to a physical system rather than a VM. -- Jonathan Billings <billings at negate.org>
