...since most of the hypervisor code, does not have a usable stack. Page tables. There's functions in lguest_debug.c that allows for dumping out either the guest page tables, or host page tables. kill_guest(linfo) - is just like i386 kill_guest and takes the lguest_guest_info pointer as input. kill_guest_dump(vcpu) - when possible, use the vcpu version, since this will also dump to host printk, the regs of the guest as well as a guest back trace. Which can be really usefull. Well that's it! We currently get to just before console_init in init/main.c of the guest before we take an timer interrupt...
