VirtualBox, CentOS, Network and Template

I have been working with VirtualBox and CentOS recently, here are some notes about this experience.
I used VirtualBox 4.2 and CentOS 6.3, but most of this should work with other products too. I created the first headless, minimal CentOS via NetInstall.
I cover two points: create a template machine and configure the Network.
Configure the NetworkWe want Internet access and a LAN local to the host.
For background information read: Networking in VirtualBox by Fat Bloke on June 2012.
The easiest is to enable two Network Adapters: One will be "Host-only" and the second "Nat". In the "Preference" menu you can see the DHCP server range for the Host-only Network. So you may set fixed addresses outside this range.
Next: start the guest. There may be various results at first, depending on a lot of things. Some problem might be solved by rm -f /etc/udev/rules.d/70-persistent-net.rules and a reboot.
Anyway, configure the two interfaces (set your own IP and MAC addresses)…
