Hi,

I'm trying to compile kvm-87 on 2.6.30-10-generic #12-Ubuntu SMP. I get:

and modprobe kvm fails due to these missing symbols.

I'm missing something here...

No, you aren't. kvm-87 is pretty broken on 2.6.30+ host kernels. You can use qemu-kvm-devel-87 with the modules from 2.6.30, and I'll try to fix things up for kvm-88.
