IMHO it would be better to just remove that warning message
and continue using existing accel=kvm:tcg syntax to specify
the preference of which accelerators to use.
Only emit "XXX accelerator not found", if there are not
further accelerators listed. eg
accel=kvm:tcg
should not print a "KVM accelerator not found" warning
when it falls back to tcg, but a
accel=kvm
would print a warning, since no fallback is given.

Daniel
