Launch a VM that boots from an ISO

To launch a VM that boots from an ISO, you must first create a VM. Let’s assume that we want to create a VM and install it from the ISO image. In this scenario, use the following command to create an empty VM:

lxc init iso-vm --empty --vm

The second step is to import an ISO image that can later be attached to the VM as a storage volume:

lxc storage volume import <pool> <path-to-image.iso> iso-volume --type=iso

Lastly, you need to attach the custom ISO volume to the VM using the following command:

lxc config device add iso-vm iso-volume disk pool=<pool> source=iso-volume boot.priority=10

The boot.priority configuration key ensures that the VM will boot from the ISO first. Start the VM and connect to the console as there might be a menu you need to interact with:

lxc start iso-vm --console

Once you’re done in the serial console, you need to disconnect from the console using ctrl+a-q, and connect to the VGA console using the following command:

lxc console iso-vm --type=vga

You should now see the installer. After the installation is done, you need to detach the custom ISO volume:

lxc storage volume detach <pool> iso-volume iso-vm

Now the VM can be rebooted, and it will boot from disk.
