CentOS - Jan 2018 - best centos server setup for graphics intensive kvm vms?

Hmm, So - I guess the best I can hope for is running the host as a full 
workstation GUI with kodi installed - forget about Libreelec - and then 
running the rest of appliances as VMs headless?

Many thanks for helping clear my thoughts on this.

Nux, thanks for you help.

I've been following and adapting this guide as necessary:
http://kodi.wiki/view/HOW-TO:Install_Kodi_on_Fedora_25_using_RPMFusion_packages
Until the point where it says to install kodi...  There is no kodi in 
RPMFusion repo for Centos, only Fedora...
But, I see that you are wrapping kodi for centos.  After a little 
searching I came across your repos here:
http://mirrors.coreix.net/li.nux.ro/nux/tmp/kodi717/

My questions
- can I use your repo as a drop in for the Fedora kodi repo at RPM Fusion?
- what's the difference between kodi7/ and kodi717/ ?

Many thanks
Morgan.
