Re: compiling with kvm-kmod
Thanks for the quick fix, I found that the modules build, but I still have a problem loading the module due to the fact that kvm_vfio_ops remains undefined in the kvm module.

compiling with kvm-kmod
Hello, I am currently working on a project involving KVM and have been making use Jan's kvm-kmod repository. I receive the below error when I attempt to compile with the most recent version. My question is simply if this is something anyone is aware of or has any suggestions for before I go poking around? I am compiling against a 3.13.0 mainline vanilla kernel and am using the master branch (3d923a3) of Jan's kvm-kmod repo which seems to be syncing from kvm commit 7650b68.
