Download a hassos_ova-X.XX.qcow2.xz release
Extract and place the qcow2 file somewhere on your unRaid system.
I use /Domains
Set up a new Linux VM (the generic Linux choice is fine)
CPU Mode: Host Passthrough
Machine: Q35-4.2 (or most recent?)
Primary vDisk Location: Manual / hassos_ova-1.6.qcow2
Primary vDisk Bus: SATA
Network Bridge: br0
Now hit update to save the edit and then start your VM. Click on the icon for it and connect via VNC.
You should shortly see the host system login (this is not the login for Home Assistant):
Wait for about 1 minute, as parts are still setting up in the background, and then enter “root”.
You should see the custom Home Assistant CLI welcome screen with your VM’s ip address and other URLs.
