Ubuntu 12.04 Netinstall URL? Xen Host

Well I have an Xen server, I've got a CentOS container up fine but a friend of mine wants (oh god) Ubuntu Server 12.04, why he can't use Debian is beyond my understanding. But anyways, I can't remember how I installed the CentOS container but I'm giving virt-manager a try now, since I don't have a disk image already the only option is to get a Network Install URL since I'm using PV.

So does anyone know what I should type in there, if it was CentOS I could easily type http://mirror.centos.org/centos/6.2/os/i386 for example. The furthest I've got in finding a suitable URL is http://archive.ubuntu.com/ubuntu/dists/precise/ but that of course wont work.

Any ideas?

Well, me being the clever person I am, I didn't set my nameservers so my server couldn't access the internet, no wonder no directory I tried worked, either way I've found it and got it working. ;)

For the reference, I used http://archive.ubuntu.com/ubuntu/dists/precise/main/installer-i386/.

If you're like me, you come here every time you need to install a new Ubuntu Server in your Xen/XCP farm. And you find that NONE of the above answers actually work. So you use them as a base, and watch the error messages to find the actual path that needs to be entered versus the final computed path that Xen creates when it appends to what you entered.

So.... for the record, the following is what actually works:

http://archive.ubuntu.com/ubuntu/dists/precise

Use that as your install URL when defining the new machine, and all works nicely. Of course, if you're looking for something other than 12.04, replace 'precise' with the name of your preferred release.

Mine works with:

• http://gb.archive.ubuntu.com/ubuntu/dists/precise/main/installer-i386/current/images/netboot/xen/vmlinuz
• http://gb.archive.ubuntu.com/ubuntu/dists/precise/main/installer-i386/current/images/netboot/xen/initrd.gz
