Multiple IP address on same VM

[Mathew Abraham]

Hi guys,

I'm bit new to Vagrant and struggling to configure a VM with two network interface using host network configuration. Single static IP address is working fine. I'm using following code. 

I can see IP 192.168.11.69 defined in ifconfig but not 192.168.11.70 ??

OS image is RHEL 7.2

hosts = [

  { name: 'wcs_local_env',      hostname: 'wcs.testlab',  username: 'vagrant',  ip: ['192.168.11.69','192.168.11.70'], mbox: 'rhel64Node', },

]

Vagrant.configure("2") do |config|

  hosts.each do |host|

    config.vm.define host[:name] do |c|

         c.vm.box = host[:box]

         c.vm.hostname = host[:hostname]

    

          host[:ip].each_with_index do |ipadr, i|

          

            if i > 0

               c.vm.network :private_network, ip: ipadr, netmask: '255.255.255.0', :adapter => i

            else

               c.vm.network :private_network, ip: ipadr, netmask: '255.255.255.0'  

            end 

         

          end 

Thanks,

Mathew

Hello

in linux, when you have a network card you should use a single network card for each segment, having 2 nics on the same segment can cause weird things with routing to other networks.

the linux way to put more than one 1 in the same network is create aliases in the network.

say you have eth1 then you can have eth1:0 eth1:1 etc.

Vagrant can have more than 1 nic on the same network, just is not what one should do.

this works:

hosts = [

  { name: 'wcs_local_env',      hostname: 'wcs.testlab',  username: 'vagrant',  ip: ['192.168.11.69','192.168.11.70'], mbox: 'centos/7', },

]

Vagrant.configure("2") do |config|

  hosts.each do |host|

    config.vm.define host[:name] do |c|

         c.vm.box = host[:mbox]

         c.vm.hostname = host[:hostname]

          host[:ip].each_with_index do |ipadr, i|

            c.vm.network :private_network, ip: ipadr, netmask: '255.255.255.0'   

          end

    end

  end

end
