Which IP we give it, will depend on the network we want to use for our VM network.Īs an example, I will use the 192.168.100.0/24 network, so I will assign 192.168.100.1 to the bridge. The next step is to configure the address for that newly created bridge. Once we are able to use TAP interfaces, we need to create the bridge where we can attach them.įor a temporal bridge we just need to issue the following command with elevated privileges: $ sudo ifconfig bridge1 create TunTap determines the max number of possible TAP interfaces and sets them up. Once it is installed, we are going to see a list of TAP nodes installed with the scheme /dev/tapX. In order to have TAP interfaces in Mac we need to download and install TunTap. The first issue I stumbled upon is the fact that Mac does not have native support for TAP interfaces. We needed to use TAP interfaces, the machines should be able to acquire the network configuration through DHCP and should be NATted.Īn schema of how I wanted things to be is as follows: Enable TAP interfaces in Mac We couldn't use QEMU's user mode network stack due to its limitations. Yes, I know QEMU's performance on Mac sucks! The project is meant to run in Linux, but as I (and all my colleagues) have a Mac to develop, we wanted to be able to run the project under Mac. I am working on a really cool project where we have to manage virtual machines that are launched through QEMU.
