[Bug 1218459] [NEW] nova-compute-kvm does not function without manually loading kvm module

[Adam Gandelman]

Public bug reported:

Note: This bug affects the precise-havana Ubuntu Cloud Archive pocket
only.

In saucy (and Havana UCA), changes were introduced to the qemu package
that modified how the CPU-specific kvm-intel/kvm-amd get loaded at
package installation time.  Where it was previously modprobe'd from a
maintainer script, it now relies on entirely on udev and modalias magic
to automatically load the correct kvm-* module for the current CPU at
boot.

This works fine in Saucy, however this all depends on 3.5+ kernels.
When using the UCA on precise with the default 3.2, we end up needing to
manually load the kvm_intel module before nova-compute-kvm+libvirt can
do anything useful.

Short of back-porting a newer kernel to UCA, it was proposed that we
carry a small delta in the qemu package that reinstates the previous
module loading.
