You absolutely need SKAS3 patches for your host kernel. You can find some
outdated information on the net that tells you that SKAS is only a
performance booster - that is simply not true for latter-day 2.6 kernels.
It is a must. I have been using various 2.6.9, 2.6.10, 2.6.11 and 2.6.12
as host - but only with proper SKAS3 patch.
I have actually used the 2.6.11 HIPL kernel as host - the one at the head
of the hipl--main--2.6 branch - works just fine - but again, only with
SKAS3 patches added. Then you can establish HIP sessions between host and
guest :-)
You get the SKAS3 patches from

That is correct, you normally don't need to patch a kernel 2.6.10 and
newer to build it as guest. Specifically, you don't need patches for
the 2.6.10 HIPL to build it as guest.
