I have received more than a couple of requests for the guide, if anyone 
else interested here is the steps I used for Ubuntu and CentOS as the 
host OS with KVM:

My guides are assuming that you are deploying a server with SR-IOV using 
the Intel x710 family of NIC's. The CentOS 7.4 guide was written a few 
days ago as I went through the install process from scratch for 18.1 to 
finally move all of the hosts I have the vMX deployed on away from 
Ubuntu to CentOS (personally I prefer Ubuntu but the old versions of 
things that are required don't give me confidence and I have had the odd 
kernel panic with Ubuntu running the vMX).

I also have the startup scripts (systemd for CentOS and init for Ubuntu) 
included for the vMX so it will start on boot; surprisingly Juniper 
doesn't give any instructions. I didn't have time to mess with selinux 
on CentOS to get the systemd startup script to work so I disabled it 
(the host is dedicated to the vMX anyyway); if you do figure out a way 
to get it working I would love to know. Happy to help as well if you run 
into any issues deploying it.
