The qemu machines enable all the 'virtio' drivers that for example instead
of talking to a pretend model of a real ethernet board, talk directly to
the container.  This makes them much faster.

The meta-intel machines enable various drivers and compiler options that
are specific to or tailored for real modern x86 hardware, so will perform
better than a lowest common denominator kernel build.
