Attach the physical interface as a member of the br-mgmt bridge.Disable DHCP on the physical interface so it doesn’t try to get an IP address automatically.Remove the IP address from the physical interface.We’ll create a new Netplan configuration to: If the interface name on your own host is different then you will need to substitute it accordingly in the instructions below.
In this case the physical interface name is eno1 and it has the IP address 192.168.10.7. If you are using a different distro you will need to consult the distro documentation for instructions instead.įirst find the interface name for the NIC in your machine using the ip address command the exact name will depend on the hardware configuration of your machine: ip addressġ: lo: mtu 65536 qdisc noqueue state UNKNOWN group default qlen 1000 I don’t recommend you disable Netplan unless you are experienced enough to deal with networking via another means. Although Netplan lacks a significant amount of advanced functionality, it’s relatively simple to set up and comes supplied out of the box. Network SetupĪs I’m using Ubuntu 20.04 we’ll configure networking using Netplan. The IP address used for accessing the host is attached to the bridge interface, not the physical interface.

When using Linux virtualisation, the most common way to attach networks to virtual machines is to use bridges – these are essentially a software representation of a network switch (a switch is in fact a multi-port bridge!). In the example below I’ll be sharing the same network with the VMs and the host.

VMware ESXi makes networking a fairly point-and-click affair in Linux you’ll need to learn how to configure networking a bit more manually.įor the sake of keeping this article as simple as possible I won’t get into VLANs just yet I’ll save that for a later post. In the first instance I’ll attempt to explain some Linux networking basics to help provide some background for those relatively new to Linux virtualisation. The same basic concepts apply to any Linux-based operating system, however you’ll need to adapt the instructions if you wish to use a different distro. I’m basing this example on Ubuntu 20.04 LTS. While it would help to have basic familiarity with Vagrant, libvirt and Linux networking, I’ve tried to make this as easy as possible to get started. Here’s a quick guide for anyone who is new to the process.
I recently had an attempt at interfacing Vagrant to libvirt/KVM/QEMU, the native virtualisation stack in Linux, and it’s a breath of fresh air! I’ve now replaced ESXi completely in favour of this setup. It’s functional but has network configuration quirks and is very slow to provision VMs as it relies on copying the image to the ESXi host for every VM creation. It works well with VMware Fusion on the MacBook but I find the ESXi support a little lacking by comparison. I’ve recently begun using Vagrant for making bulk provisioning much faster, easier and more repeatable.

I’ve been using a VMware ESXi box as the foundation for a home lab for many years now, but without the benefit of the full (expensive!) vSphere/vCenter suite it’s a relatively tedious affair for managing anything beyond a tiny handful of virtual machines.
