Hi folks, With this series, the bulk of the work of pvops64 is done. Here, I integrate most of the paravirt.c and paravirt.h files, making them applicable to both architectures. CONFIG_PARAVIRT is _not_ present yet. Basically, this code is missing page table integration (patches currently being worked on by Jeremy). Enjoy

Hi, all, I have difficulty on setting up lguest. Basic OS info: gcc 4.1.2 glibc: 2.5.1 binutils: 2.17 kernel: 2.6.23-rc1 Following lguest.txt instruction, I build lguest enaled kernel, disable CONFIG_COMPAT_VDSO, the host kernel boot fine, but when booting Qemu image using lguest laucher program, the guest kernel vmlinux panic, attached console.txt is console output, and config.txt is kernel

As promised to Andrew, and with much thanks to Andi Kleen for feedback, this is the new series of lguest patches. Main change is the move to drivers/lguest (for future non-i386 expansion), but lots of cleanups driven by Andi's feedback and the documentation effort (which made me examine every line of code). It's not perfect, but it's definitely useful. Cheers, Rusty. List of
