Windows VM using LXD

It’s not entirely obvious how to create a Windows Virtual Machine when using LXD. Here are the most basic steps to get it up and running. This is largely for my own documentation but will probably help someone else out there I’m sure.

The easiest option is to embed the VirtIO drivers directly into the Windows ISO using distrobuilder (via snap). This is the method I’ll be demonstrating. Alternatively, you could attach both ISO’s and when it comes to selecting a drive to install to (during windows installer) you’ll have to click the ‘load drivers from removable media’ and select them from their.

First, install the needed tools. Note, you’re more than welcome to compile distrobuilder from source, but using the snap is much quicker.

sudo snap install distrobuilder --classic
sudo apt install -y libguestfs-tools wimtools

Proceed to download the needed ISOs. You can download Windows ISO HERE and VirtIO ISO HERE.

Now we’re ready to embed the drivers directly into the Windows ISO. Here’s the command:

sudo distrobuilder repack-windows /home/shaner/Downloads/win10_21H2.iso ./win10_packed.iso --drivers=/home/shaner/Downloads/virtio-win.iso

Next, we create an empty machine (VM),set the disk size, and attach our custom ISO with virtio drivers.

lxc init win10pro --empty --vm -c security.secureboot=false
lxc config device override win10pro root size=40GiB
lxc config device add win10pro iso disk source=/home/shaner/win10_packed.iso  boot.priority=10

Now, start the machine and attach to the VGA console to walk-through the installer:

lxc start win10pro --console=vga

Once the install is complete, be sure to enable Remote Desktop as it’s a much better experience than using the LXC (spice) console.
