So, I've been trying this out. But i ran into the problem where if the /lib/modules was mounted in the dom0 xen wouldn't let me start a domU with it as one of the disk entries. Is there any way around this, am i overlooking something? for now i made a lvm snapshot of the /lib/module partition so i could get my domU's back up and running.

Thanks,
Jeff
I use a shared /usr partition between my dom0 and all the domU's. You may be able to do something like that.

Create a logical volume to contain /lib/modules/2.6.xx-xen. Export it in your domU definitions as one of the "disk = []" entries, read only, then add a mount line in each of your domU's for it. Guaranteed to be the same on each domU.

BTW, none of my domU's even has a /boot partition.
