Ok,
Thank you for your prompt response. I can see this in the nova.conf file:
[libvirt] ... virt_type = kvm ...
Can I assume qemu is using virtualization through kvm?
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.
not in all cases. you can turn on hypervior hiding which may or may not be viable to endusers in a public cloud setting.
