Avoid Unity, KDE, or Gnome3. The heavier DEs might work on a local-only setup. I've never tried that. Basically, I always use remote connections.
I never install guest OSes with UEFI. Always use legacy BIOS.
I have never installed 18.04 on any physical machine. Maybe next year, after it has some time to prove is it a great OS. My primary VM server runs 14.04 and 2 others are running 16.04.
"New" is the enemy of "stable."
When you use KVM, it is actually better to use UEFI for the VM if your graphics card supports it - see Intel IGD and arbitration bug (my summary).
I've tried virt-manager several times and regretted it every time. The last time (August 2018) I spent a week installing and re-installing a Windows 10 VM to get the performance I am used to. Mind you, it wasn't such a problem to get the Windows VM up and running, but performance kinda sucked. Eventually I got it working more or less, but the hassle of using a GUI and then having to edit the resulting xml config file using some antiquated editor (vim or so) really put me off.
@TheFu: I assume you are a moderator? Perhaps you could update the sticky "The Virtualization Mega-Thread" - it is kind of ancient. There is more up-to-date information on the web (see also my website, which has plenty of links to other sources too). I'd be glad to help out if needed.
Edit: I would usually subscribe to your "New" is the enemy of "stable" phrase, but Ubuntu 18.04 and the newer qemu 2.11 does bring some improvements. Let alone virt-manager, which greatly improved despite my bashing it once again.
