Even after I add this file, I can't even manually "ifup" the interface!

# nmcli con
NAME                UUID                                  TYPE           
DEVICE
Wired connection 1  3a02edd8-e82d-4dca-a336-933e9177f4cd  802-3-ethernet 
eth0
# ifup eth0:0
Error: no device found for connection 'System eth0:0'.
# nmcli con
NAME                UUID                                  TYPE           
DEVICE
System eth0:0       81ad1dc6-9516-a6cf-73d9-600036a810a1  802-3-ethernet  --
Wired connection 1  3a02edd8-e82d-4dca-a336-933e9177f4cd  802-3-ethernet 
eth0
# nmcli con reload
# nmcli con
NAME                UUID                                  TYPE           
DEVICE
Wired connection 1  3a02edd8-e82d-4dca-a336-933e9177f4cd  802-3-ethernet 
eth0

Even if I add a line NAME="System eth0:0" to the ifcfg-eth0:0 file, it
still doesn't work...
