Home Assistant VM on eisy Error - Unsupported system - virtualization_image

[pablohoney]

Setup Home assistant VM a few weeks ago following these instructions: https://developer.isy.io/blog/Home Assistant

Did updates yesterday to Home Assistant and am now getting an "Unsupported system - virtualization_image" error.

Screen capture below and HA information on this error here: https://www.home-assistant.io/more-info/unsupported/virtualization_image

HA state solution is to reinstall Home Assistant OS using an image which supports being run on a virtualized system.

Will this be supported on the eisy?

I got that initially, but I tried again later and it worked fine. I'm not sure what changed.

Maybe it was fixed with 2024.4.2, which came out yesterday, but maybe after my first attempt and before my second?

I'm running 2024.4.2 and have the error. Did a restart of HA and error remains.

The error is legit, but it is just a warning. The script on the blog uses the generic x64 OS image instead of one of the VM tailored images. They don’t have a FreeBSD VM image specifically but when I have some time I’ll see if I can get one of the other VM images running instead.

For now it should be reasonably safe to ignore.

Thanks for the insight on the image used in the script. I've done 3-4 updates and the error just now displayed.

Anyone find a fix for this yet?

I finally had a few cycles to take a look at this.  I wrote up a modified script that will use the VM based Home Assistant images instead of the one meant for bare metal.  I also added some other tweaks that allow you to choose to enable access to the VM via console, VNC, and SSH during install.  Unfortunately there isn't an easy way to "fix" an existing install so you'll need to start from scratch or you can try backing up and restoring your HA config but no guarantees there.

To start this will delete your current VM and all related configs.  It will completely destroy your existing Home Assistant VM so only run this if you want to start fresh or are sure you have all the backups you need.

sudo vm poweroff -f homeassistant
sudo vm destroy -f homeassistant
sudo vm switch destroy public
sudo zfs destroy storage/vms

Here is a new create_ha_vm.sh script.  Save it and run it with sudo.

see updated version below

 

@Michel Kohanim it might be worth updating the blog post with this script so new installs get the proper image.

@apnarI ran your script and it seemed like it ran fine except for an error on line 126 which I think should not affect HA. It shows like homeassistant VM is running but homeassistant.local:88123 does not come online at all and not even showing up in my router with an IP address. If I go to the VNC address it has a shell prompt but if I back out of that it seems like it is the Bhyve loader and I think HA is crashing but can not find any proof of that. I was able to rerun my old script an load the old HA again with no problem.

@tazman thanks for giving it a try.  Took me a bit but I tracked down the issue.  I use a significantly bigger sized virtual disk in my setup but had dropped it down to 16GB when I uploaded it to match what was in the original script.  Even though the OVA file from HA is only 800MB they have it configured as a 32GB virtual disk so when it was trying to be copied to the smaller 16GB volume it errored out.  Guess that's what I get for thinking a small tweak wouldn't cause any issues.

As to the error on line 126, I'm not seeing that but suspect it might be related to posting the shell script on the forum.  So I added some extra quoting and I'll upload it as a file here in addition to pasting it.

@apnar thanks for your work on this! I was giving mine 50G of space so that should not have been a problem for me. I will give it another try over the weekend.

@apnarthank you for your work on this! I downloaded the file and everything worked for me and I only change 2 lines
