[Qemu-devel] [PATCH] Remove debugging messages.

["Richard W.M. Jones" <rjones@redhat.com>]

From: "Richard W.M. Jones" <rjones@redhat.com>

When using qemu -machine accel=kvm:tcg, if KVM is not available you
get a load of debugging output:

  Could not access KVM kernel module: No such file or directory
  failed to initialize KVM: No such file or directory
  Back to tcg accelerator.
