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.

Install Qemu and some dev tools.

Note: You will likely have to install Xcode CLI tools.
```
brew install qemu autoconf automake wolfssl
```
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
```
Set your WiFi to be the primary internet link:
1. Click on the wifi icon in the top right of your screen.
2. In the bottom left of the pop up, select the menu dropdown and click on Set Service Order
3. Drag WiFi to the top.
4. Click OK then click Apply

Now, install VDE for bridged networking:

mkdir -p ${OKD_LAB_PATH}/work-dir
cd ${OKD_LAB_PATH}/work-dir
git clone https://github.com/virtualsquare/vde-2.git
cd vde-2
autoreconf -fis
./configure --prefix=/opt/vde
make
sudo make install

Finally, set up the network bridge device:

cd ${OKD_LAB_PATH}/work-dir
git clone https://github.com/lima-vm/vde_vmnet
cd vde_vmnet
make PREFIX=/opt/vde
sudo make PREFIX=/opt/vde install
sudo make install BRIDGED=${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
