Issue/Introduction
vCSA 7.0 supports Multi-Homing NICs but Multi-Homing does not work with VCHA.
vCSA 7.0 supports up to 4 NICs, prior versions of the vCSA supported only a single NIC.
When a vCSA with multiple NICs is configured for VCHA only the first NIC (eth0) is managed by VCHA, the other NICs will be copied with identical confuration to the Passive and Witness Nodes, resulting in duplicate IPs.
