Re: [Xen-API] XAPI create PV (para-virtualized) Ubuntu guest 14.04

[Olivier Lambert <lambert.olivier@xxxxxxxxx>]

I'm not an Ubuntu specialist, but any recent kernel handles Xen
flawlessly (everything needed is included). You don't have to install
anything particular in your guest, treat it like any other system.
About "xe-guest-utilities", these are only need to have more
informations on your guests (it's an "agent" reporting data to the
host). It's not mandatory to get your guest working.

If you want more information to have a "light" Ubuntu system, I think
their forum are a good place to start!
