RE: [Xen-users] Kernel drivers on domU

First basic rule: Keep the kernel as small as possible.
Second basic role: Hardware is typically controlled by dom0.

Hence, you don't need real hardware drivers in domUs.

However if you want to passthrough PCI devices, you will need their drivers
in domU.
Current source tarballs by default build only one kernel anyway, giving you
all drivers anywhere.
