Greetings!!
I have a single Raspberry Pi 4B. I have installed Balena OS onto it. I would be grateful, if someone would outline, how I would setup a virtual machine on it?
Many thanks, in advance.
Kind regards,
Tony.
Hello Tony and welcome to the balena forums 
balenaOS is not meant to host virtual machines of any kind, its meant for running Moby compatible containers (e.g. Docker ). So if you’re looking for something like VMware or VirtualBox to run different kind of VMs on the RPi 4B+, balenaOS is not the correct solution - and you would need to work with something like the VMware ESXi ARM Fling ( ESXi Arm Edition | VMware Flings ). However, if you want to find out how to e.g. run a containeraized Python application on the RPi 4B+ using balenaOS, you can checkout the get started guides of balena: Get started with Raspberry Pi 4 and Python - Balena Documentation
Cheers,
Nico
Hello, Nico.
Thank you for your prompt reply. Ah, that explains why I couldn’t find something on it. 
. I had tried Esxi-arm already, but was having problems getting it to locate my SSD drive; so, after approximately a week of trying, I gave-up defeated.
Coming back to Balena OS: I have set-up my Pi running PiHole as a release. I have pulled the Docker container for Home Assistant. It does run, but for some reason, I cannot find the the Home Assistant GUI.
Again, any assistance would be appreciated.
Perfect, I just wanted to make sure that there is no confusion .
With Home Assistant, do you mean the project balenaHub: an easier way to find and publish apps and projects for edge devices or did you directly use balenaHub: an easier way to find and publish apps and projects for edge devices or the balena version of homeAssistant ( GitHub - balenalabs-incubator/balena-homeassistant: Raspberry Pi + Home Assistant + balenaSense )?
What I did was “balena run homeassistant/home-assistant”, which I believe runs the Docker container.
I have another problem. Every evening around this time, I’m unable to access my RPi 4. I cannot ssh into it, and the Balena Dashboard says: “Online (VPN only)”. The only way, which I have been able to resolve this, is to physically power-cycle my RPi4.
Yes, you are using the official homeassistant container that way. However, I would not advise to use it this way, as you still should mount some external components etc… Homeassistant has its own tutorials on how to get it up and running: Raspberry Pi - Home Assistant - with its own operating system.
The error you see could be a full sdcard, as I found this on the forum. I think it would be more useful to follow the official homeassistant guide without balena if you’re starting up fresh - its less complicated.
Thank you for the prompt reply. I have only just taken my finger off the click button. 
I had thought of that, I also wanted to run PiHole, as well.
