Seems independent of dom0 kernel or guest kernel (though they're all various forms of pvops). I see it on two separate machines.Does it depend on the amount of domU RAM? If so, how much exactly poses problem? Please also paste the MiniOS start log talking about memory addresses& such. Below is the full crash with 512MB. I tried 32, 64, 128, 256 and 1024MB with much the same results, though sometimes it just hung in a spin loop rather than crashing (inconsistent from boot to boot, not a function of memory size). I also noticed when booting the Fedora 12 distro kernel it did actually start the kernel, but it failed to make much progress (or at least, no console output). The same kernel boots fine with pygrub.
