[CentOS-virt] Using network-script with Xen 4.4.1 (aka what will I do without xend?)

I normally use the network-script parameter in the '/etc/xen/xend-config.sxp' configuration file to configure network bridges. However, the latest release of Xen4CentOS (which comes with Xen 4.4.1) has xend disabled by default.

Can I continue to use network-script without xend? If not what is the recommended method for automatically configuring network bridges with the latest release of Xen4CentOS?

I know I can just enable xend to continue using this script, but since Xen 4.5 is apparently dropping xend altogether I figure I should change my standard configuration starting now.

Thanks in advance for your time.
