First step in creating your Home Assistant (HaaS) VM on your Proxmox Server is to get your HaaS OS image to do this we need to go to the HaaS web page https://www.home-assistant.io/ from there main page click Getting Started and go all the way to the bottom of the page to where is saids Install Home Assistant on other systems and click View tutorial. Under Download the appropriate image you will see KVM/Proxmox this is where you will right click and select Copy link Address if you are on a Mac if using windows the Copy link Address botton might have a different name

after you have the link address you can open your Proxmox shell window from you Proxmox Web Interface and enter the command

wget https://github.com/home-assistant/operating-system/releases/download/14.1/haos_ova-14.1.qcow2.xz

Above is the link address for HaaS 2025.1 you will need to enter the link address for you version of HaaS

Now you need to build a VM and there are some things you need to pay attention to

General just set the Name

qm importdisk <VMID> <HaaS File Name> local-lvm

when this finishes you need to go back to the web interface select the VM then select Hardware select the unused disk hit edit and add
