Setup LXD to obtain local IP on VirtualBox VM

Step 1: Configure VirtualBox VM Network Settings

1. Stop your VirtualBox guest VM.
2. Open the Settings for the VM.
3. Navigate to the Network section.
4. In Adapter 1 (or an unused adapter tab), ensure the Enable Network Adapter checkbox is selected.
5. Change the Attached to: dropdown to Bridged Adapter.
6. In the Name dropdown, select your host machine’s physical network interface (e.g., enp0s3, eth0, or the name of your physical Wi-Fi/Ethernet adapter) that is connected to your local network/router.
7. Set Promiscuous Mode to Allow VMs or Allow All.
8. Click OK to save the settings and start the VM. 

1. Create a new Netplan configuration file (e.g., 99-lxd-bridge.yaml) in /etc/netplan/.
2. Edit the file, replacing enp0s3 with your actual guest physical interface name (found using ip addr or ifconfig): 

network:
  version: 2
  renderer: networkd
  ethernets:
    enp3s0:
      dhcp4: no
  bridges:
    br0:
      dhcp4: yes
      interfaces:
        - enp3s0
      parameters:
        stp: false

network:
  version: 2
  renderer: networkd
  ethernets:
    enp3s0:
      dhcp4: no
  bridges:
    br0:
      dhcp4: yes
      interfaces:
        - enp3s0
      parameters:
        stp: false

Apply the Netplan configuration with sudo netplan apply (this will briefly disconnect you if using SSH). 

Update the Profiles: “LXD UI > Profiles > default” “yaml” file as below.
