Can I install Ubuntu as Minimal Virtual Install (formarly called Ubuntu JeOS1) on Xen hypervisor or not?

Does it only support KVM and VMware?

1. Ubuntu JeOS a version of Ubuntu that can be installed with the Server CD selecting "Minimal virtual machine" at the install screen.

    @AndreaCorbellini - none of the download links in the JeOS wiki appears to be working. Looks unsupported at first glance. – fossfreedom Sep 6 '13 at 12:07
  • @fossfreedom: the wiki page is outdated. As I said, "JeOS" is an ancient name. What was called JeOS is now known as the "minimal virtual installation" of the server CD. The linux-virtual package that you see in the official repos belongs to it. – Andrea Corbellini Sep 6 '13 at 12:12
  • It took me a while, but eventually I found the announcment! JeOS has also been renamed to Minimal Install – Andrea Corbellini Sep 6 '13 at 12:17
  • So, what version of Ubuntu are you using? the old one still named "JeOS" or a new supported version with the minimal install? – Mateo Sep 6 '13 at 13:34

The Ubuntu minimal virtual install differs from the standard server install in two ways:

  1. lesser packages are installed;
  2. a different kernel is installed.

Before Oneiric, the kernel was the one provided by the linux-image-*-virtual packages. Nowadays, the kernel used by the minimal install is linux-image-*-generic. Instead, standard server and desktop installs use both linux-image-*-generic and linux-image-extra-*-generic.

All of this to say that if the minimal install does not work, it's because it lacks some drivers and modules that are shipped with the extra package.

So, the question is: are the drivers sufficient to run Ubuntu on Xen? I don't know and I can't try at the moment. If vmbuilder does not let you use Ubuntu Minimal with Xen, it's a different matter.

What I can say is that Launchpad PPA builders and Amazon EC2 run on Xen, and I am pretty sure that neither of them are using the extra kernel package.
