Re: instances from template not coming up with networking (eth0) on rhel5/6
the default build adds the mac address to a couple places.
Here is a script I wrote to deal with it, Run before creating the template
#!/bin/bash
ed /etc/udev/rules.d/70-persistent-net.rules <<__EOF__
/eth0
d
w
q
__EOF__
for i in /etc/sysconfig/network-scripts/ifcfg-eth*
do
ed ${i} <<_EOF_
/HWADDR
d
w
q
_EOF_
done

You can also just delete the
/lib/udev/rules.d/75-persistent-net-generator.rules from the template.
That creates the /etc/udev/rules.d one. So with both of those gone,
you'll get an eth0 even when your mac changes.

Thanks I'll add this and see if it helps!
Since I work templates a bunch, I'm interested in helping with
documentation on the guest side/collect handy scripts, etc. Let me know
the best way to get my feet wet.
Happy Friday!
