opnfv vm requires connectivity to two physical interfaces of the host.
These interfaces are:
1 - admin, where DHCP requests will arrive from blades to do PXE boot
2 - mgmt, which connects to the mgmt of the blades to do the ansible
configuration
To achive this, it is required:
1 - Two libvirt networks that connect to two different linux bridges.
The important physical interfaces are connected to them. The
interfaces name is fetched from the idf
2 - Two templates representing the new libvirt networks
(net-mgmt.xml.j2 and net-admin.xml.j2)
3 - Two interfaces defined in vm.xml.j2
