It sounds like a simple thing to do: As Ubuntu does not have support for Xen by default, I wanted to run a Debian Lenny Server as Xen host (Dom0) with Ubuntu Lucid (10.04) LTS as guest (DomU). But there were some obstacles:
- debootstrap does not support Ubuntu Lucid by default
- Ubuntu Lucid cannot boot using the Debian Lenny kernel in para-virtualized mode
In this post I want to show you all the steps to come up with a nice and simple setup to be able to run Ubuntu 10.04 LTS as Xen DomU on Debian Lenny as Xen Dom0 using xen-tools to create new VMs.
