Running pintos using Bochs and gdb

This recording shows how to invoke pintos in debugging mode. I’m showing Bochs here; Qemu works as well (–qemu –gdb), although you’ll see different characteristics.

KVM (–kvm) does not work (it doesn’t allow setting breakpoints). It’s recommended to use only one CPU (–smp 1) for debugging, although multiple CPU should work as well (they’ll show up as different threads in gdb)
