add qemu ppa to get qemu 1.4 utils. needed because qemu has to be started
outside of the libvirt framework because we need netdev socket support.
couldn't figure out how to use qemu 1.0 that came with ubuntu 12.04. got it
working with qemu 1.4
fixing some errors when starting this setup on a clean system. reverting back to
the kvm installed by 12.04. found it has the necessary options i need
add missng pkgs required to setup kvm environment
