Huh. Running a more recent Xen release with an older kernel on Fom0 is kind of begging for incompatibility, I'd suspect.

What is in /var/log/xen/*? And what does "yum list extras" say, in case you pulled non-FC6 or non-FC7 packages while working with things? And have you tried building any new images and looking for differences in the config files? FC6 was xen 3.0.3, FC7 is Xen 3.1.0.



Nico,
I'm steering away from trying to get cross version working - too many dependencies. What has to happen in our case is that Fedora has to fix the libata problems so that we could use an F7 kernel. I may try just getting VMWare server working in the interim until libata gets fixed and we can go back to using Xen.
By doing a yum upgrade rather than a clean install, or booting with an FC7 medium, you've skipped out on the kernel compatibility testing that goes with that step. I sympathize: I used to get paid good money to resolve exactly that sort of update and compatibility fun. So what you have is not really a Xen problem: it's an "FC7 kernel-xen won't boot my hardware" problem, right? Will the non-Xen FC7 kernel boot your hardware?

Can you boot this hardware with an FC7 installation CD or DVD?
