Heavily reworked the networking for the various virtual machines:

There will be three types of network interfaces for virtual machines available
all will be configured for every type of virtualization tool
a) br0 is the direct host bridge into the local LAN (br0 already exists)
   vmnet0 for VMware
   vboxnet0 for VirtualBox
   kvmnet0* for Qemu/KVM
b) nat1 is an internal bridge which "NATes" into the local LAN (with DHCP)
   vmnet1 for VMware
   vboxnet1 for VirtualBox
   kvmnet1* for Qemu/KVM
c) vsw2 is an internal host bridge to connect software defined LANs to
   vmnet2 for VMware
   vboxnet2 for VirtualBox
   kvmnet2* for Qemu/KVM
