[PATCH 1/2] paravirt.h header
OK, this is the revised paravirt.h (Andi has seen this before), then the
second is the binary patching stuff. More things get added to the
paravirt struct in future patches, but this basic stuff hasn't changed
for some time.
====
This patch does the dumbest possible replacement of paravirtualized
instructions: calls through a "paravirt_ops" structure. Currently
these are function

[PATCH 0/7] x86 paravirtualization infrastructure
The following patches introduce the core infrastructure needed to
paravirtualize the 32-bit x86 Linux kernel. This is done by moving
virtualization sensitive insn's or code paths to a function table,
paravirt_ops. This structure can be populated with hypervisor specific
calls or native stubs and currently support running on bare metal, VMI,
Xen, or Lhype. These patches apply to

lguest doesn't work on kernel 2.6.23-rc1
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
