i tried it another way - well with other kinds of thirdparty modules,
but this did it for me:
- - cp your linux-2.6.11-xenU source tree into your domU (e.g. /usr/src/..)
- - check, you're using same compiler version in domU than in dom0
- - (eventually) modify .config/Kconfig to match the version name
(linux-2.6.11-xenU instead
of linux-2.6.11)
- - just make modules && make modules_install as you would do in dom0
i don't know, if this is a preferred way of getting working domU
modules, but - as said -
this did it for me.
btw. if you're only concerned about one module, why don't you build
this statically into
the kernel ?
