Linux kernel development with KVM

I tried the following command (in the linux-2.6 directory, checked out via git)... kvm -kernel arch/x86/boot/bzImage -initrd /boot/initrd.img-2.6.38-10-generic -append "console=ttyS0" -nographic

Failing to load some modules and not mounting anything. I think I'm missing some crucial step, I'm pretty unfamiliar with virtualization.
