Proxmox Permissions

To be able to retrieve the status of VMs and containers, the user used to connect must minimally have the VM.Audit privilege. To be able to controls the VMs and containers, the user used to connect must have the PVEVMAdmin role. Below is a guide to how to configure a new user with the minimum required permissions.

Create Home Assistant Group

Before creating the user, we need to create a group for the user. Privileges can be either applied to Groups or Roles.

Click Datacenter
Open Permissions and click Groups
Click the Create button above all the existing groups
Name the new group (e.g., HomeAssistant)
Click Create

Add Group Permissions to all Assets

For the group to access the VMs we need to grant it the auditor role

Click Datacenter
Click Permissions
Open Add and click Group Permission
Select "/" for the path
Select your Home Assistant group (HomeAssistant)
Select the Auditor role (PVEAuditor)
Make sure Propagate is checked

For the group to control the VMs, we need to grant the admin role.

Click Datacenter
Click Permissions
Open Add and click Group Permission
Select "/" for the path
Select your Home Assistant group (HomeAssistant)
Select the VM Admin role (PVEVMAdmin)
Make sure Propagate is checked

Create Home Assistant User

Creating a dedicated user for Home Assistant, limited to only to the access just created is the most secure method. These instructions use the pve realm for the user. This allows a connection, but ensures that the user is not authenticated for SSH connections.

Click Datacenter
Open Permissions and click Users
Click Add
Enter a username (e.g., homeassistant)
Set the realm to "Proxmox VE authentication server"
Enter a secure password (it can be complex as you will only need to copy/paste it into your Home Assistant configuration)
Select the group just created earlier (HomeAssistant) to grant access to Proxmox
Ensure Enabled is checked and Expire is set to "never"
Click Add

In your Home Assistant configuration, use homeassistant@pve for the username and your chosen password for the password.
