I did not want move to the new kernel from kvm.git.
I generally find that it works well, though I only run it on servers.
I just wanted to
upgrade to the latest kvm module for some development. Is there a way
to use the kvm.git tree and only build and load kvm?
kvm-kmod.

The only thing I see in dmesg is:
loaded kvm module (v2.6.39-8627-g2c2b5df)
if (mod->init != NULL && mod->exit == NULL) {
printed_something = 1;
seq_printf(m, "[permanent],");
}
I don't recall anything in kvm-kmod playing with these, so it's a
mystery why this happens.
kvm.ko doesn't have an init or exit function. kvm-intel.ko has both.
Wierd.
