Is it possible to set up a Hardy domU on an existing Xen dom0 running Dapper? I have found many postings talking about the reverse (Dapper domU on a Hardy dom0), but I have the existing server set up with a Dapper dom0 and a few Dapper domUs. I need to set up a new domU, so I want to use a more modern LTS release. I am hesitant to upgrade the dom0, on the "if it ain't broke, don't fix it" principle.
Has anyone tried this? Can I just use a 2.6.24 Xen kernel? Do I need to recompile the domU kernel to match anything in my dom0?
Or is it necessary to upgrade the dom0?
