virt-manger ovmf

I want to configure a VirtuaI Machine graphically and the virt-manager, qemu packages offered by Ubuntu are a tad too old for my taste so I used the virtualization PPA for Ubuntu (ppa:jacob/virtualisation) to get the latest qemu and libvirt without getting into the headache of compiling them. After that I used

to get the OVMF option in libvirt and virt-manager but virt-manger threw this warning After some searching I found out that the OVMF image supplied with Ubuntu is quite old so I found a fairly recent one in the unstable packages of Debian 8. After I downloaded it I installed and restarted libvirt-bin using:

But still virt-manager would not see OVMF. After some more searching I found this page that explains when virt-manger displays the warning:

After reading that I realized that the 3rd option was surely the problem, meaning that when I installed OVMF (either from the Ubuntu PPA or the deb package) it did not create the necessary links in /etc/libvirt/qemu.conf. Opening it I found at the bottom of the file that I have to list the OVMF images in this format:

Here is where I hit a wall. I don't know what or how to make an OVMF_VARS file. I only have one image in /usr/share/ovmf/ and I don't understand how I can split it or what is the syntax for the qemu.conf file to put just the unified image.

PS: I'm a noob when it comes to Linux & Visualization so I'm sorry if my question seems easy or stupid.
