Accidently sent this directly to OP,

You'll want to download the libvirt SRPM for CentOS 6.  Based on the comment from the spec file , RHEL and CentOS is purposely not compiled with openvz,

# RHEL doesn't ship OpenVZ, VBox, UML, OpenNebula, PowerHypervisor,
# VMWare, or libxenserver (xenapi)
%if 0%{?rhel}
%define with_openvz 0

To enable openvz you change that define to 1 and then rebuild using the spec.

You can extract the SRPM contents with...

rpm2cpio libvirt-xxxx.src.rpm | cpio -dimv

Then follow this documentation, http://wiki.centos.org/HowTos/RebuildSRPM , to rebuild a new RPM.

Hope that helps,
