I am using the config copied from the Debian kernel. 'grep XEN' has the
following:

CONFIG_X86_64_XEN=y
CONFIG_X86_XEN_GENAPIC=y
CONFIG_XEN_PCIDEV_FRONTEND=y
# CONFIG_XEN_PCIDEV_FE_DEBUG is not set
CONFIG_XEN=y
CONFIG_XEN_INTERFACE_VERSION=0x00030207
# XEN
CONFIG_XEN_PRIVILEGED_GUEST=y
# CONFIG_XEN_UNPRIVILEGED_GUEST is not set
CONFIG_XEN_PRIVCMD=y
CONFIG_XEN_XENBUS_DEV=y
CONFIG_XEN_NETDEV_ACCEL_SFC_UTIL=m
CONFIG_XEN_BACKEND=y
CONFIG_XEN_BLKDEV_BACKEND=m
CONFIG_XEN_BLKDEV_TAP=m
CONFIG_XEN_NETDEV_BACKEND=m
# CONFIG_XEN_NETDEV_PIPELINED_TRANSMITTER is not set
CONFIG_XEN_NETDEV_LOOPBACK=m
CONFIG_XEN_PCIDEV_BACKEND=y

CONFIG_XEN_SCSI_FRONTEND=m

CONFIG_XEN_KEYBOARD=y
CONFIG_XEN_SCRUB_PAGES=y

CONFIG_XEN_SYSFS=y
CONFIG_XEN_COMPAT_030002_AND_LATER=y
# CONFIG_XEN_COMPAT_030004_AND_LATER is not set
# CONFIG_XEN_COMPAT_030100_AND_LATER is not set

CONFIG_XEN_COMPAT=0x030002
CONFIG_XEN_SMPBOOT=y
CONFIG_XEN_BALLOON=y
CONFIG_XEN_DEVMEM=y

Anything in there that shouldn't be?
