As Dan noted in his response, it's because it is reporting the libvirt driver
name (which is reported as QEMU).
Refer below if you want to double-confirm if your instances are using KVM.

That means, yes, you using KVM. You can confirm that by checking your QEMU
command-line of the Nova instance, you'll see something like "accel=kvm":
# This is on Fedora 23 system
$ ps -ef | grep -i qemu-system-x86_64
[...] /usr/bin/qemu-system-x86_64 -machine accel=kvm [...]

<pre wrap="">....
<emulator>/usr/bin/qemu-system-x86_64</emulator>
But according to this document [1], it is using QEMU emulator instead of
KVM, because it is not using /usr/bin/qemu-kvm
So I really don't know if it's using KVM or QEMU.

As noted above, a sure-fire way to know is to see if the instance's QEMU
command-line has "accel=kvm".
A related useful tool is `virt-host-validate` (which is part of libvirt-client
package, at least on Fedora-based systems):
$ virt-host-validate | egrep -i 'kvm'
QEMU: Checking if device /dev/kvm exists : PASS
QEMU: Checking if device /dev/kvm is accessible : PASS
