Guide to Bridged Networking
|
|
===========================
|
|
To set up bridged networking for the macOS VM, use one of the following methods:
|
|
|
|
|
|
## Using /etc/network/interfaces
|
|
|
|
It is possible to create the bridge and tun/tap interfaces by adding the following lines to `/etc/network/interfaces`. Replace `DEVICENAME` with your ethernet card's device name, and `MYUSERNAME` with the user that is starting the VM.
|
|
|
|
```
|
|
auto br0
|
|
iface br0 inet dhcp
|
|
bridge_ports DEVICENAME tap0
|
|
|
|
auto tap0
|
|
iface tap0 inet dhcp
|
|
pre-up tunctl -u MYUSERNAME -t tap0
|
|
```
|
|
|
|
## Using NetworkManager
|
|
You can use NetworkManager to control the bridge and tun/tap interfaces, by creating them with the following commands. Replace `DEVICENAME` with your ethernet card's device name.
|
|
|
|
### Make the Bridge
|
|
```
|
|
nmcli connection add type bridge \
|
|
ifname br1 con-name mybridge
|
|
```
|
|
|
|
### Attach Bridge to Ethernet
|
|
```
|
|
nmcli connection add type bridge-slave \
|
|
ifname DEVICENAME con-name mynetwork master br1
|
|
```
|
|
|
|
### Make the Tun/Tap
|
|
```
|
|
nmcli connection add type tun \
|
|
ifname tap0 con-name mytap \
|
|
mode tap owner `id -u`
|
|
```
|
|
|
|
### Attach Tun/Tap to Bridge
|
|
```
|
|
nmcli connection mod mytap connection.slave-type bridge \
|
|
connection.master br1
|
|
```
|
|
|
|
## Attach Bridge to QEMU
|
|
Once you have set up the bridge and tun/tap on the host, you'll have to add the following line to `basic.sh`, replacing `-netdev user,id=net0`. Change `tap0` to your corresponding device name.
|
|
|
|
```
|
|
-netdev tap,id=net0,ifname=tap0,script=no,downscript=no \
|
|
```
