==== 1.2 Install the Home Assistant Virtual Machine on Ubuntu Server Linux ====

Before, we chose “local install media” when installing Ubuntu Server to our virtual machine for mailcow, but Home Assistant is a little different. It’s an operating system that is all ready to go – it’s installed, configured, etc. We are going to be choosing the “import existing disk image” option to boot it up.

* '''Open Virtual Machine Manager''':
** Right-click on the desktop of your Ubuntu Server.
** Navigate to '''Applications &gt; System &gt; Virtual Machine Manager'''.
* '''Create a New Virtual Machine''':
** Once Virtual Machine Manager is open, click on '''Create a new virtual machine'''.
** In the wizard that appears, choose the option '''Import existing disk image'''.
** Unlike the past virtual machine where we were installing an operating system from scratch, this is an image of an operating system that has already been “installed” and configured elsewhere; therefore, all we need to do is import it.
* '''Select the Home Assistant Image''':
** When prompted to choose an installation source, browse to <code>/var/lib/libvirt/images/</code> and select the Home Assistant <code>.qcow2</code> image you moved in the previous step.
* '''Choose Operating System Type''':
** Select '''Generic Linux 2022''' as the operating system type. The official Home Assistant instructions suggest using a “generic” Linux option.
* '''Set Memory and CPU Allocation''':
** Set the RAM to 2048 MB (2 GB).
** Assign 2 CPUs to the virtual machine.
** It is recommended to use 2 CPUs, even though this might feel like overkill for a thermostat-related function. And it does.
* '''Name the Virtual Machine''':
** In the same setup window, name the virtual machine <code>homeassistant</code>.
* '''Customize Configuration Before Installation''':
** Before clicking '''Finish''', make sure you check the box that says '''Customize configuration before install'''.
* '''Set Firmware to UEFI''': you want UEFI x86-64: <code>/usr/share/OVMF/OVMF_CODE_4M.fd</code> – DO NOT CHOOSE THE ONE THAT SAYS “SECBOOT”

'''Set up this virtual machine to start every time the host computer, happycloud, boots by typing this into a terminal:'''

<pre>virsh autostart homeassistant</pre>
* Check that this is set up properly by typing <code>virsh dominfo homeassistant</code> and seeing if the autostart line is set to enable.
* If you don’t do this, you will realize once it is too late &amp; you’ve left your house after you have rebooted your server (for whatever reason) that none of your services are working. This will suck.
