Where best to start

[Martin Hargreaves <m.l.hargreaves@xxxxxxxxx>]

Dear Xen Community,

I’m new to the field of virtualization so please excuse this request if 
it is placed on the incorrect forum.
I am running Ubuntu 18.04 and following the instructions on...

https://help.ubuntu.com/community/Xen

and not getting anywhere fast. I found out that the above instructions 
are out of date for Ubuntu 18.04, because the networking has been 
implemented differently
https://askubuntu.com/questions/1171864/how-to-install-xen-project-on-ubuntu-server-18-04-3-lts

However, when I make this change my machine can no longer access the 
internet.
I have searched on https://xen.markmail.org/ but not really found a 
clear answer to my question:
Please can anyone let me know the best way to get Xen up and running on 
Ubuntu? Should I try to put Ubuntu 16.04 on my m/c and then follow the 
instructions given?
And for the best tutorial? I have seen that there is “The Definitive 
Guide to the Xen Hypervisor” by David Chisnall (2008)  and “Running Xen: 
A Hands-on Guide to the Art of Virtualization” by Jenna Matthews et. Al 
(2008) but will these help with installing and using the current version?
  Thank you for any insights that anyone may have.

    Martin...
