Which you must do using 'ARCH=xen', i.e. one of 

# make ARCH=xen menuconfig
# make ARCH=xen xconfig
# make ARCH=xen gconfig

I believe you failed to add the 'ARCH=xen' when building the config.

Yes, indeed - your .config file is a 'vanilla linux' config file
rather than a Xen one; you should always see

CONFIG_XEN=y
CONFIG_ARCH_XEN=y 

at the start of a XenLinux .config file.

This is correct, but not the problem in this case; Robert's issue 
was biting him much earlier.

        ^^^^^^^^             

This is the important bit!
