I am working on setting up a Kubernetes cluster over the network LAN.

Problem: Unable to get an IP static addresses for the VM guests on the LAN.

Settings

Guest OS : Ubuntu

Host OS: Windows10

Firewall settings are disabled on windows 10

Type of network adapter on Virtual Box is bridged

ipconfig on the guest os :

This is the ifconfig result:

This a part of my Vagrantfile configuration:

s.vm.network "private_network", ip: "192.168.3.50",virtual_box__intnet: true,# netmask: "255.255.255.0",
      auto_config: true


      s.vm.network "public_network", bridge: "Intel(R) Ethernet Connection I217-LM", ip: "192.168.2.50",# netmask: "255.255.255.0",
      auto_config: true


      s.vm.provider "virtualbox" do |v|

        v.name = vM_NAME
        v.memory = 2048
        v.gui = false
        v.customize ['modifyvm', :id, '--nictype3', 'Am79C973']
        v.customize ['modifyvm', :id, '--nicpromisc3', 'allow-all']
        v.customize ['modifyvm', :id, '--nicpromisc2', 'allow-all']
        v.customize ['modifyvm', :id, '--nicpromisc1', 'allow-all']

Troubleshooting

1. Tried to ping from the host OS to guest and it worked.

2. Tried to ping between hosts OS and it worked.

I am trying to have w static ip on the LAN for the Vms (The kubernetes nodes), to join them over the network across different hardware server.

Thank You.
