Could it be that 2.6.26 is a little > too old kernel to run as host for the newer kvm? Maybe. I'm only testing against 2.6.27 as oldest host, down to 2.6.24 is solely build-tested. Maybe the missing MMU notfiers in <= 2.6.26 cause troubles, though this used to work before. Can't promise that I find the time to look into this (such old kernels are out of official scope). If I managed to, I would try to bisect over kvm-kmod-2.6.32 what import from kvm.git or what kvm-kmod wrapping brought us the breakage. But maybe someone else finds the time, setup support would be provided...
