There's also --machine parameter accel.  From --help:

                property accel=accel1[:accel2[:...]] selects accelerator
                supported accelerators are kvm, xen, tcg (default: tcg)

Example: --machine accel=kvm:tcg tries KVM, and if it's unavailable, it
falls back to TCG.

There's only one build.  The resulting binary is intended to serve as
drop-in replacement for qemu-kvm.  Please report any regressions.
