If `virt_type = kvm` is set, then yes, your instance should be using
KVM.

You can confirm it in a couple of ways:

  - Check that your Nova instance's QEMU process has this in its QEMU
    command-line: "-machine accel=kvm".  (`ps -ef | grep qemu`, and look
    for the relevant process.)

  - SSH into your instance, run `systemd-detect-virt` (or `virt-what` if
    you have it).  It should report 'kvm', if KVM is really being used.
