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

Hi Olivier,

Which packages should I install on Ubuntu guest?
I know it is silly question... but searching around points me all the time to xe-guest-utilities which I can't find as I'm using XenProject hypervisor 4.4 installed on Ubuntu from buildroot.

This is certainly some silly point... but all related to xen kernel points me to xen-hypervisor.

Thanks for help!

PV means your guest "knows" it is virtualized, because its kernel
itself is modified to talk directly to Xen [0]. It doesn't mean
minimal filesystem occupation. However, if you want to have minimal
footprint on your guest, you can rely on Ubuntu server installation
[1] (likewise to the Debian netinstall without selecting any extra
packages), or use minimalist distro.

The other alternative is to use unikernel OS, like Mirage [2].

Hi Guys,

Could any of you point me to how to create PV guest with minimal filesystem

I've update template for Ubuntu 14.04 following

But I have no idea how to create PV system from CLI.

I've created VM using Xen Orchestra and it seems to be PV system based on
parameters however XO forced me to use ISO image or URL. I've chosen ISO but
while it still installs it took already 1.4GB of disk space for minimal

Is this the way it should be or there is some minimalistic approach?
