Do you have a checked out Linux tree in linux-2.6/?
Currently, the linux-2.6 submodule seems to reference
a commit that is not present in the standard kvm
repo, so I assume that git submodule update
has failed for you. For now, you can fix this by
using git checkout in linux-2.6/

Btw.: Wrt. git sync, I've also updated to README
a bit to the two different kernel trees that come into
play. Comments?

Jan: I think the bogous reference is a leftover
from the tree that you've added as submodule; after
my patch to use Avi's tree, the information might be
out of sync.
