How to build and spin up a VM using an image downloaded from the Internet

I recently started an online class which provided a VM image in an OVA format. I run Linux as my main OS and like to use libvirt and KVM as they seem as close to native as possible. In other words, with libvirt and KVM, I am running a virtualization platform that is as close to the Linux OS as possible. ie. it is leveraging virtualization support in the kernel itself, and libvirt seems to be the most commonly used virtualization software on Linux.
