Re: Where best to start

[Dave Hill <davehill@xxxxxxxxx>]

I'm not a Ubuntu user so can't help there but the first thing I would do generically is check that the bridge is working:

brctl show

should yield something like this:

    bridge name     bridge id               STP enabled     interfaces
    xenbr0          8000.4ccc6ad1847d       no              enp2s0

As for a tutorial, I'd suggest at least having a look through the Xen Begginers Guide:

https://wiki.xenproject.org/wiki/Xen_Project_Beginners_Guide

It's dated (in particular, I wouldn't follow the advice there for building a PV Debian guest), but it contains the essentials to get Xen working generically.

Also, since your network stopped working, I'd go back and check that your netplan configuration matches the one in the link you sent. The key is that dhcp is not enabled on the ethernet card (eth0 or enps0 or whatever), but rather on the bridge.
