Follow this guide if you already are running a supported virtual machine hypervisor. If you are not familiar with virtual machines we recommend installation Home Assistant OS directly on a Raspberry Pi or an ODROID.
Load the appliance image into your virtual machine hypervisor. (Note: You are free to assign as much resources as you wish to the VM, please assign enough based on your add-on needs).
Minimum recommended assignments:
- 2 GB RAM
- 32 GB Storage
All these can be extended if your usage calls for more resources.
- Create a new virtual machine
- Select Type “Linux” and Version “Linux 2.6 / 3.x / 4.x (64-bit)”
- Select “Use an existing virtual hard disk file”, select the unzipped VDI file from above
- Edit the “Settings” of the VM and go “System” then “Motherboard” and select “Enable EFI”
- Then go to “Network” “Adapter 1” choose “Bridged Adapter” and choose your Network adapter
- Then go to “Audio” and choose “Intel HD Audio” as Audio Controller.
By default VirtualBox does not free up unused disk space. To automatically shrink the vdi disk image
discard option must be enabled:
VBoxManage storageattach <VM name> --storagectl "SATA" --port 0 --device 0 --nonrotational on --discard on
- Create a new virtual machine in
- Select “Import existing disk image”, provide the path to the QCOW2 image above
- Choose “Generic Default” for the operating system
- Check the box for “Customize configuration before install”
- Select your bridge under “Network Selection”
- Under customization select “Overview” -> “Firmware” -> “UEFI x86_64: …”
- Click “Add Hardware” (bottom left), and select “Channel”
- Select device type: “unix”
- Select name: “org.qemu.guest_agent.0”
- Finally select “Begin Installation” (upper left corner)
virt-install --name hass --description "Home Assistant OS" --os-variant=generic --ram=2048 --vcpus=2 --disk <PATH TO QCOW2 FILE>,bus=sata --graphics none --boot uefi
- Start the Virtual Machine
- Observe the boot process of Home Assistant Operating System
- Once completed you will be able to reach Home Assistant on homeassistant.local:8123. If you are running an older Windows version or have a stricter network configuration, you might need to access Home Assistant at homeassistant:8123 or
http://X.X.X.X:8123(replace X.X.X.X with your ’s IP address).
With the Home Assistant Operating System installed and accessible you can continue with onboarding.
This is an advanced installation process, and some steps might differ on your system. Considering the nature of this installation type, we assume you can handle subtle differences between this document and the system configuration you are using. When in doubt, please consider one of the other installation methods, as they might be a better fit instead.
This guide assumes that you already have an operating system setup and have installed Python 3.9 (including the package
python3-dev) or newer.
Before you start, make sure your system is fully updated, all packages in this guide are installed with
apt, if your OS does not have that, look for alternatives.
sudo apt-get update sudo apt-get upgrade -y
Install the dependencies:
sudo apt-get install -y python3 python3-dev python3-venv python3-pip bluez libffi-dev libssl-dev libjpeg-dev zlib1g-dev autoconf build-essential libopenjp2-7 libtiff5 libturbojpeg0-dev tzdata
The above-listed dependencies might differ or missing, depending on your system or personal use of Home Assistant.
Add an account for Home Assistant Core called
Since this account is only for running Home Assistant Core the extra arguments of
-rm is added to create a system account and create a home directory.
sudo useradd -rm homeassistant
First we will create a directory for the installation of Home Assistant Core and change the owner to the
sudo mkdir /srv/homeassistant sudo chown homeassistant:homeassistant /srv/homeassistant
Next up is to create and change to a virtual environment for Home Assistant Core. This will be done as the
sudo -u homeassistant -H -s cd /srv/homeassistant python3 -m venv . source bin/activate
Once you have activated the virtual environment (notice the prompt change to
(homeassistant) [email protected]:/srv/homeassistant $) you will need to run the following command to install a required Python package.
python3 -m pip install wheel
Once you have installed the required Python package, it is now time to install Home Assistant Core!
pip3 install homeassistant
Start Home Assistant Core for the first time. This will complete the installation for you, automatically creating the
.homeassistant configuration directory in the
/home/homeassistant directory, and installing any basic dependencies.
You can now reach your installation via the web interface on
If this address doesn’t work you may also try
http://X.X.X.X:8123 (replace X.X.X.X with your machines’ IP address).
When you run the
hass command for the first time, it will download, install and cache the necessary libraries/dependencies. This procedure may take anywhere between 5 to 10 minutes. During that time, you may get “site cannot be reached” error when accessing the web interface. This will only happen for the first time, and subsequent restarts will be much faster.
