Set Up a MacBook for Qemu with Bridged Network

Note: This is part of a series. Make sure you started here: Building a Portable Kubernetes Home Lab with OpenShift - OKD4

Let’s set up a MacBook to run the OpenShift Bootstrap node.

  1. Install Qemu and some dev tools.

    Note: You will likely have to install Xcode CLI tools.

    brew install qemu autoconf automake wolfssl
  2. Plug in your USB-C network adapter and identify the device:

    1. Run this to list all of your devices:

      networksetup -listallhardwareports
    2. Look for the USB entry:

      Mine looked like this:

      Hardware Port: USB 10/100/1G/2.5G LAN
      Device: en6
      Ethernet Address: 00:e0:4c:84:ca:aa
    3. Note the Device name, and set a variable:

      export BOOTSTRAP_BRIDGE=en6
  3. Set your WiFi to be the primary internet link:

    1. Click on the wifi icon in the top right of your screen.

      Network Preferences

    2. In the bottom left of the pop up, select the menu dropdown and click on Set Service Order

      Set Service Order

    3. Drag WiFi to the top.

      Set Service Order

      Set Service Order

    4. Click OK then click Apply

  4. Now, install VDE for bridged networking:

    mkdir -p ${OKD_LAB_PATH}/work-dir
    cd ${OKD_LAB_PATH}/work-dir
    git clone
    cd vde-2
    autoreconf -fis
    ./configure --prefix=/opt/vde
    sudo make install
  5. Finally, set up the network bridge device:

    cd ${OKD_LAB_PATH}/work-dir
    git clone
    cd vde_vmnet
    make PREFIX=/opt/vde
    sudo make PREFIX=/opt/vde install
    sudo make install BRIDGED=${BOOTSTRAP_BRIDGE}

Resetting The Bridge Device

It will be necessary to reset the bridge device from time to time after a reboot, or unplugging the NIC.

labcli --reset-nic
