When using NetworkManager instead of the ifcfg-eth1/eth0 files - I make a
nmcli connection and modify "Wired connection 1" +ipv4.addr IP/22
kind of command - it works - which is great. It "adds" the virtual IP.

However - when doing ifconfig that "virtual" IP does not show up.  When
using NetworkManager - to add the virtual IP - how do I get that to show
using ifconfig also ?
it used to show as eth1:0
