    Configure Networking in Fedora 28 OVH Proxmox

    OVH have special networking requirement. First you need to login OVH and create vMAC for your IP address. Now create VM in Proxmox, during VM creation, specify this vMAC address under Network > MAC.

    Proxmox create virtual machine

    Once your VM is installed, you don’t have network access. Login to the server using Proxmox Console.

    Run following commands

    ip addr add FAILOVER_IP dev ens18
    ip route add GATEWAY_IP dev ens18
    ip route add default via GATEWAY_IP dev ens18
    

    Replace following in above commands

    FAILOVER_IP = IP address of your Virtual Machine.

    GATEWAY_IP = This is gateway IP addres. This is IP address of your host machine (the server on which proxmox installed). Replace last digit with 254. For example, if your servers main IP is 123.123.123.142, then use 123.123.123.254 as gateway.

    Here is an example

    ip addr add 158.69.138.120 dev ens18
    ip route add 192.95.29.254 dev ens18
    ip route add default via 192.95.29.254 dev ens18
    

    At this point, you will be able to login to server using SSH. You may not able to ping outside, for this, you need to edit /etc/resolv.conf and add nameserver entry.

    vi /etc/resolv.conf
    

    Add

    nameserver 8.8.8.8
    

    To make it permanant, edit

    vi /etc/sysconfig/network-scripts/ifcfg-ens18
    

    Find

    BOOTPROTO=dhcp
    

    Replace with

    BOOTPROTO=static
    IPADDR=FAILOVER_IP
    GATEWAY=GATEWAY_IP
    HWADDR=MY:VI:RT:UA:LM:AC
    DNS1=1.1.1.1
    

    Example

    [root@ip120 ~]# cat  /etc/sysconfig/network-scripts/ifcfg-ens18
    TYPE=Ethernet
    PROXY_METHOD=none
    BROWSER_ONLY=no
    BOOTPROTO=static
    IPADDR=158.69.138.120
    GATEWAY=192.95.29.254
    HWADDR=02:00:00:46:f4:52
    DEFROUTE=yes
    IPV4_FAILURE_FATAL=no
    IPV6INIT=yes
    IPV6_AUTOCONF=yes
    IPV6_DEFROUTE=yes
    IPV6_FAILURE_FATAL=no
    IPV6_ADDR_GEN_MODE=stable-privacy
    NAME=ens18
    UUID=cf4c9d14-92ec-3475-94e2-797b405ac516
    ONBOOT=yes
    AUTOCONNECT_PRIORITY=-999
    DEVICE=ens18
    [root@ip120 ~]# 
    

    For routung, create

    vi /etc/sysconfig/network-scripts/ifcfg-ens18-route
    
    GATEWAY_IP - 255.255.255.255 ens18
    default GATEWAY_IP
    

    Example

    [root@ip120 ~]# cat /etc/sysconfig/network-scripts/ifcfg-ens18-route
    192.95.29.254 - 255.255.255.255 ens18
    default 192.95.29.254
    [root@ip120 ~]#
