I just bk-clone'd the latest unstable, rebuilt everything (including using the new 'make ARCH=xeno' syntax*** for building xenolinux) and on boot, I got:

DOM0: Unable to obtain IOPL, despite being SIF_PRIVILEGED

Just to make sure, I repeated everything and still got the same result. (I know... that's the definition of insanity ;-)

Maybe I got bits in the middle of somebody's checkin? It's getting late on Friday here so I will try it again next week, but wanted to report it in case there is a bigger problem.

*** By the way, the new syntax is inconsistent with 2.6 linux builds so this new requirement may generate a lot of confusion. Xen uses

make ARCH=xxx

and Linux 2.6 uses

ARCH=xxx make

and they are definitely different. I'm no make expert and this may be unrelated but doing

make ARCH=xeno oldconfig dep bzImage

doesn't work for me unless I do the steps with separate make's.
