Device /dev/Xen2Volume/domU-kernel-needed is mounted read-write in the
privileged domain,
and so cannot be mounted read-only by a guest.

This seems to indicate that the device "/dev/Xen2Volume/domU-kernel-needed" is mounted read-write in dom0. You need to unmount it or mount it read-only in dom0 to use it in a guest.
