No, there is absolutely *NO* need to install libvirt when compiling the
Xen RPM - there is no compile time dependancy, and you certainly should
not use --nodeps when installing RPMs.

Did you install both xen & xen-libs ?

The version of Xen you installed  probably has a newer libxenstore.so
which includes versioning, while the libvirt you installed was linked
against the older non-versioned libxenstore.so. What does 

  rpm -q --provides xen xen-libs | grep xenstore

Show ?

BTW, you'll also want libvirt-python RPM too
