How many Network Interface Cards are required to install Arno for OPNFV? I am installing fuel and OPNFV system according to "Fuel deployment: Installation Guide" in the following web site: https://www.opnfv.org/software/download It is said that 3 NIC cards per computer (Private/Public network, SAN, admin) are required to install OPNFV for the Arno release. However, there are only 2 NICs per servers. Do I need 2 separate NICs for private and public network? Or is one NIC enough because private network is just virtual network which doesn't require physical NIC? I don't need SAN currently.
Thank you for your answer in advance,
