Hi,
I have successfully installed FCOS in KVM from ISO.

Now I added another NIC to the VM, and after rebooting DHCP assigns an IP to this new NIC:
[core@vm191-fcos ~]$ nmcli device
DEVICE  TYPE      STATE            CONNECTION
eth0    ethernet  verbunden        Wired connection 1
eth1    ethernet  verbunden        Wired connection 2
lo      loopback  nicht verwaltet  --
[core@vm191-fcos ~]$ nmcli device show eth1
GENERAL.DEVICE:                         eth1
GENERAL.TYPE:                           ethernet
GENERAL.HWADDR:                         BE:05:3F:16:2C:CD
GENERAL.MTU:                            1500
GENERAL.STATE:                          100 (verbunden)
GENERAL.CONNECTION:                     Wired connection 2
GENERAL.CON-PATH:                       /org/freedesktop/NetworkManager/ActiveConnection/2
WIRED-PROPERTIES.CARRIER:               an
IP4.ADDRESS[1]:                         192.168.100.102/24
IP4.GATEWAY:                            192.168.100.11
IP4.ROUTE[1]:                           dst = 0.0.0.0/0, nh = 192.168.100.11, mt = 101
IP4.ROUTE[2]:                           dst = 192.168.100.0/24, nh = 0.0.0.0, mt = 101
IP4.DNS[1]:                             10.17.200.80
IP4.DNS[2]:                             10.17.122.10
IP4.DOMAIN[1]:                         
IP6.ADDRESS[1]:                         fe80::50f7:c9cd:ec1e:e75/64
IP6.GATEWAY:                            --
IP6.ROUTE[1]:                           dst = fe80::/64, nh = ::, mt = 101
IP6.ROUTE[2]:                           dst = ff00::/8, nh = ::, mt = 256, table=255

However I don't want NetworkManager to control this NIC eth1.
This should be a static IP.

Can you please advise how to disable NetworkManager to control this NIC?
