Hi Todd,

Thanks for your reply.

Of those missing from -generic, -server has:

CONFIG_XEN=y
CONFIG_XEN_MAX_DOMAIN_MEMORY=8
CONFIG_XEN_SAVE_RESTORE=y
CONFIG_XEN_BLKDEV_FRONTEND=m
CONFIG_XEN_NETDEV_FRONTEND=m
CONFIG_XEN_KBDDEV_FRONTEND=m
CONFIG_XEN_FBDEV_FRONTEND=m
CONFIG_XEN_BALLOON=y
CONFIG_XEN_SCRUB_PAGES=y
CONFIG_HVC_DRIVER=y
CONFIG_HVC_IRQ=y
CONFIG_HVC_XEN=y

That looks like all the ones you listed, but it still gives the same
boot error.

Do you know what other config options would be required?

Having to compile a kernel would suck a bit, but if it worked at all
it would be progress..

Cheers,
Andy
