![]() ![]() ![]() Multipass needs to create a bridge to connect to eth0. Mpbr0 bridge Network bridge for Multipass On Linux, when trying to connect an instance network to an Ethernet device on the host, Multipass will offer to create the required bridge: $ multipass networks $ multipass exec upbeat-whipsnake - ip route get 192.168.1.13 So, by default the instance will only route through them if they’re a better match for the destination IP: $ multipass exec upbeat-whipsnake - ip routeĭefault via 10.0.2.2 dev enp0s3 proto dhcp src 10.0.2.15 metric 100ĭefault via 192.168.1.1 dev enp0s8 proto dhcp src 192.168.1.146 metric 200ġ0.0.2.0/24 dev enp0s3 proto kernel scope link src 10.0.2.15ġ0.0.2.2 dev enp0s3 proto dhcp scope link src 10.0.2.15 metric 100ġ92.168.1.0/24 dev enp0s8 proto kernel scope link src 192.168.1.146ġ92.168.1.1 dev enp0s8 proto dhcp scope link src 192.168.1.146 metric 200 enp0s9 - the interface that is connected to bridge0 on the host, ready for manual configuration.Įxtra interfaces are configured with a higher metric (200) than the default one (100). ![]() enp0s8 - the interface that is connected to en0 on the host and which is automatically configured.enp0s3 - the default interface, that the instance can use to reach the outside world and which Multipass uses to communicate with the instance.In the example above, we got the following interfaces inside the instance: $ ping -c1 192.168.1.146 # elsewhere in the same network $ multipass exec upbeat-whipsnake - ip -br address show scope global Here is an example: $ multipass launch -network en0 -network name=bridge0,mode=manual but a simpler form with only is available for the most common use-case. These properties can be specified in the format =,…. mac - a custom MAC address to use for the device.mode - either auto (the default) or manual with auto, the instance will attempt automatic network configuration.name - the only required value, it identifies the host network to connect the instance’s device to (see networks for possible values).Each use takes an argument specifying the properties of the desired interface: The -network option can be given multiple times, each one requesting an additional network interface (beyond the default one, which is always present). on macOS, with both QEMU and VirtualBox.on Windows, with both Hyper-V and VirtualBox.And then only in the following scenarios: So, from 17.10 and core 16 onward, except for snapcraft:core16. This is supported only for images with cloud-init support for Version 2 network config, which in turn requires netplan to be installed (inside the instance). That is complemented by the networks command, to find available host networks to bridge with. Multipass can launch instances with additional network interfaces, via the -network option. ![]()
