CentOS virt - Jan 2015 - 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.

I have seen those documents, I did not see anything that indicates how
_automatic_ bridge configuration could be enabled with xl.

For my specific set up I have two bridges (xenbr0 -> peth0 & xenbr1 ->
peth1).  If I have to configure this manually with ifcfg scripts I will,
but if an automatic method is provided or is possible with xl I'd prefer to
use that.

Hello,

You should set up the bridges using distro networking scripts, so
/etc/sysconfig/network-scripts/ifcfg-*
That's the supported and preferred way.

(It was the recommended way also with xend, that's why xen network-script
was disabled as a default).
