kvm: OVMF file and steps 3 and 4

[anselmolsm]

Describe the error/improvement to an existing document or image

In the guide to run Clear Linux as a KVM guest OS, section "Download and launch the virtual machine":

• Step 3 tells users to download the OVMF file (side note: there could be a copy&paste friendly curl line to download it);
• Step 4 tells user to do a cp of the same file from /usr/share/qemu.

These steps seem to conflict (imagine if the user downloads the file to workdir, then follow step 4... one file would overwrite the other).

Considering the recommendation in the "Note" after those steps, it seems steps 3 and 4 target different users: step 3 non-CL hosts, step 4 CL hosts.

Still, I downloaded OVMF from the link provided then compared (md5sum) that file with the one at /usr/share/qemu in my Clear Linux host, and they are different... So that made me think: Which version is the best to use?

Environment (please complete the following):

• Clear Linux OS version: 28230
