How do I auto-start Xen guests on boot?

Question

I have just upgraded to Ubuntu Server 12.04 and permanently run a Xen guest.

We have migrated to the xl toolstack for Xen (from xm) as suggested which unlike xm does not have support for managed domains. xm is being removed in Xen 4.2 so I need to migrate away.

How should I configure my host to autostart Xen guests?

Answer 1

www.gossamer-threads.com/lists/xen/users/259014 suggests to me that Xen 4.1 with xl is unfortunately not a great combination.

The "fix" is to go back to xm until Xen 4.2 is packed in Ubuntu, at which point xendomains won't depend on xend, so you can start guests at boot and use xl.
