Look as I have, I have failed so far to find a good guide or a definition of what a "minimal Xen Dom0 system" entails. Any help to find this information would be appreciated.
Quoting "minimal Xen Dom0 system" from https://help.ubuntu.com/community/Xen
In particular I am interested in understanding what is required to be installed in Dom0 (using Ubuntu 18.04) so that I have a fully functioning (home) Xen set-up where all guests have access to the network, USB ports, HD, screen/X11/GUI & all as if they were (almost) the sole user of the hardware. And more to the point what is not required to be installed in Dom0 (for instance do I need an X11 server in Dom0?).
For info my set-up is a 2011 laptop with i7 processor, 8GB RAM, a fresh 500GB SSD, ATI graphics card. My use: open office/Internet/programming (data & machine learning)/video editing.
