A simple web gui for controlling Proxmox VMs & nodes. Specifically for the use case of using a headless proxmox server as a workstation with multiple VMs sharing a single GPU and switching between them as required.

It uses a Flask and Proxmoxer (https://github.com/proxmoxer/proxmoxer) to monitor status and control powering on/off VMs or nodes. It also includes basic detection of conflicts in VFIO pcie devices shared between VMs.

The default credentials are admin:admin. The password can be changed once logged in.

NB - Various assumptions on deployment platform are made in the below instructions, the below relates to Ubuntu.

• Create a proxmox pam user "vmupdown"
• Create a 'Role' in proxmox called 'vmupdown' and give it the following privileges:
  Sys.PowerMgmt, VM.Audit, VM.PowerMgmt
• Create 'Permissions' for both /nodes and /vms for the user and role above.
• Create an API Token for the vmupdown user. Disable 'Privilege Separation'. Note it down.
• Fill out the variables in config.py with values appropriate to your setup, for example:

token = "31dc4f09-871e-44eb-9392-4e38b63aab2b"
nodes = {
        "qproxmox-01": {"ip": "192.168.20.2", "mac": "d6:09:6b:f3:72:ec", "status": ""},
        "qproxmox-02": {"ip": "192.168.20.3", "mac": "d6:09:6b:f3:72:ec", "status": ""}
        }
sharedgpu = "0000:0f:00"

Example docker compose file:

version: '3.3'
services:
    vmupdown:
        container_name: vmupdown
        ports:
            - '8080:8000'
        volumes:
            - '/path/to/vmupdown/config.py:/var/www/html/vmupdown/config/config.py'
            - '/path/to/vmupdown/db:/var/www/html/vmupdown/db'
        restart: unless-stopped
        image: lupinelab/vmupdown

Create the db folder and set permissions. eg:

mkdir /path/to/vmupdown/db
chown 33:33 /path/to/vmupdown/db

Run the container:

docker-compose up -d

APT:

apt install apache2 libapache2-mod-wsgi-py3 wakeonlan python3-pip

PIP:

pip install flask proxmoxer requests

• Configure apache2 to listen on port 8080 in /etc/apache2/ports.conf:

...
Listen 8080
...

• Copy vmupdown folder into /var/www/html and adjust permissions:

cp -R vmupdown /var/www/html/
chown -R www-data:www-data /var/www/html/vmupdown
chmod +x /var/www/html/vmupdown/vmupdown.*

• Copy vmupdown.conf to /etc/apache2/sites-available and then enable site:

a2ensite vmupdown

• Reload apache:

systemctl reload apache2

• You should now be able to load the site on http://serveripaddress:8080
