I have used Open Virtuosso for about a year now.
My HN,runs eight VE containers.
In reading various HOWTO articles on the WIKI,everyone seems to think that you have to write a mile long script,covering front to back,in getting persistent virtual Ethernet networking,up and running on a HN,or VE.
First,a bridge can be configured statically. (i.e ifcfg-br0)
Second,VETH devices can be added to a bridged adapter,via writing a simple,"rc" type file,to load at boot. These files load after all *.init scripts.
And lastly,persistent Ethernet setups in a VE,can be achieved also,by a static configuration (i.e ifcfg-eth0) and an rc.* file,to add routing entries,within a VE container.
This method works for me,and could get someone up and running,and they in turn,can advance the scripts to suit them.
No complex scripts,and no mucking around in the vz.conf file,as some Author's suggest.
Although,dynamic scripting in some cases,has its virtue,why try to reinvent the wheel?
A simple HOWTO,on virtual Ethernet networking,would go a long way for those who may be new to OpenVZ,or are not that well versed,in LINUX scripting.
Any advanced scripting,could be added to the HOWTO,as value reading.
After all,no one is born with a keyboard or mouse in their hands,even though some,would like to make you think,otherwise.
Just a thought.

The answer to this question from me,is "No".
Complex scripting is not required,even at the level I use OpenVZ.
(traffic conditioning,VPN,GRE tunnels)
I always choose the simplist method of configurations.
Although,static VETH configurations on the Node server will cause "error" messages to be displayed upon boot-up(no VETH device found),this is simply has to do with run-level timings between the "network" daemon,and OpenVZ.
This was an easy fix,as I created an "init" garbage collecter script,to remove all known "VETH" configurations,and create a "loader" script,to transfer all "VETH" configurations from a given directory,just before OpenVZ starts.
This script was later changed to add specific kernel keys that OpenVZ and/or networking required.
