Why do you set xen's driver "m"?

Hi, Aron

I failed to boot domainU, then I checked FC6's config.
Why do you set xen's driver to "m"?
I think the following driver should be "y".

CONFIG_XEN_NETDEV_BACKEND=m
CONFIG_XEN_NETDEV_FRONTEND=m
CONFIG_XEN_BLKDEV_BACKEND=m
CONFIG_XEN_NETDEV_LOOPBACK=m
CONFIG_XEN_BLKDEV_FRONTEND=m

Best Regards,
