and following patch by Kyle McMartin solves this issue, this patch posted on 20 Feb to LKML but not CC'd to you.

From: Kyle McMartin <kyle@xxxxxxxxxxx>

lguest uses asm-offsets to generate ... offsets, obviously, for use
in the lguest switcher code. When the hypervisor code is built as a
module though, the asm offsets it needs won't be generated since
CONFIG_LGUEST will be undefined.

Linux is like living in a teepee. No Windows, no Gates and an Apache in house!
