Home Assistant OS (HAOS) runs well in a Proxmox VM and keeps your smart home isolated from your Docker host.

1) Create the HAOS VM

Download HAOS image

Get the KVM/Proxmox disk image (QCOW2) from Home Assistant releases.

Create VM shell

• Name: homeassistant
• CPU: 2 cores
• RAM: 4–8 GB
• Disk: create minimal disk or none (we’ll import)
• Network: VirtIO

Import the HAOS disk

On Proxmox host:

qm importdisk <VMID> /path/to/haos.qcow2 local-lvm

Attach imported disk:

• VM → Hardware → Add → Existing Disk
• VM → Options → Boot Order → set imported disk first

2) First boot + onboarding

Start VM and access:

• http://<ha-ip>:8123

3) Optional: USB passthrough (Zigbee/Z-Wave)

• VM → Hardware → Add → USB Device

4) Automatic HA backups to NAS

Goal: backups live outside the HA VM disk.

Create a dataset

Example: tank/backups/homeassistant Share via SMB or NFS.

Use a backup add-on

Common approach:

• Install a backup add-on (e.g., Samba Backup)
• Configure it to store backups on your NAS share

Verify backups

• Ensure files appear in the NAS dataset
• Test restoring a backup at least once (practice is priceless)
