Yes, modprobe is silent on success.

There don't seem to be many Xen modules there. This may be OK if those
options are =y in your kernel configuration or it may be a problem if
they are =m.

Can you attach your kernel config please. Also the output of
        find /lib/modules/$(uname -r) -name xen\*.ko
might be interesting.
