Proxmox Plugin

A convenient Oh My Zsh plugin for managing Proxmox Virtual Environment (PVE) from the command line. This plugin provides easy-to-use commands for common VM operations like listing, starting, stopping, and monitoring virtual machines through the Proxmox VE REST API.

Features

• VM Management: List, start, stop, and gracefully shutdown VMs
• Status Monitoring: Check individual VM and cluster node status
• Tab Completion: Auto-complete VM IDs for faster command execution
• Colored Output: Enhanced readability with color-coded status messages
• Error Handling: Clear error messages and configuration validation
• Multiple Authentication: Supports various Proxmox authentication realms

Requirements

• Proxmox VE Server: Access to a Proxmox VE installation
• Network Access: HTTPS connectivity to your Proxmox server (port 8006)
• Valid Credentials: Proxmox user account with appropriate permissions
• curl: Command-line tool for API requests (usually pre-installed)

Required Proxmox Permissions

Your Proxmox user needs at minimum:

• VM.PowerMgmt - To start/stop VMs
• VM.Monitor - To check VM status
• Sys.Audit - To list VMs and nodes

Installation

1. Clone the Oh My Zsh repository or add this plugin to your existing installation:

   git clone https://github.com/ohmyzsh/ohmyzsh.git ~/.oh-my-zsh
   

2. Add proxmox to your plugins list in ~/.zshrc:

   plugins=(git proxmox ... other-plugins)
   

3. Configure your Proxmox credentials by adding these environment variables to your ~/.zshrc:

   export PROXMOX_HOST="proxmox.example.com"    # Your Proxmox server hostname/IP
   export PROXMOX_USER="root@pam"               # Username@realm
   export PROXMOX_PASSWORD="your-password"      # User password
   export PROXMOX_NODE="node1"                  # Optional: specific node name
   

4. Reload your shell configuration:

   source ~/.zshrc
   

Configuration

Environment Variables

Variable	Required	Description	Example
PROXMOX_HOST	Yes	Proxmox server hostname or IP	proxmox.example.com
PROXMOX_USER	Yes	Username with authentication realm	root@pam or admin@pve
PROXMOX_PASSWORD	Yes	User password	your-secure-password
PROXMOX_NODE	No	Specific node name (auto-detected if not set)	pve-node1

Authentication Realms

Common Proxmox authentication realms:

• @pam - Linux system users
• @pve - Proxmox VE authentication server
• @ad - Active Directory
• @ldap - LDAP server

Usage

Available Commands

Command	Description	Example
pve-list	List all VMs with status	pve-list
pve-start <vmid>	Start a virtual machine	pve-start 100
pve-stop <vmid>	Force stop a virtual machine	pve-stop 100
pve-shutdown <vmid>	Gracefully shutdown a VM	pve-shutdown 100
pve-status <vmid>	Get detailed VM status	pve-status 100
pve-cluster	Show cluster nodes status	pve-cluster
pve-help	Display help information	pve-help

Command Aliases

For faster access, these short aliases are available:

• pvels → pve-list
• pvestart → pve-start
• pvestop → pve-stop
• pvestatus → pve-status
• pvecluster → pve-cluster

Tab Completion

The plugin supports tab completion for VM IDs. Start typing a command and press Tab to auto-complete available VM IDs:

pve-start <Tab>    # Shows available VM IDs
pve-status 1<Tab>  # Completes VM IDs starting with 1

Examples

List all VMs

$ pve-list
Fetching VM list...
VMs on node pve-node1:
ID      Name            Status          Memory  CPUs
──────────────────────────────────────────────
100     ubuntu-web      running         2048MB  2
101     debian-db       stopped         4096MB  4
102     windows-ad      running         8192MB  4

Start a VM

$ pve-start 101
Starting VM 101...
VM 101 start command sent successfully

Check VM status

$ pve-status 100
Status for VM 100:
Status: running
Name: ubuntu-web
CPUs: 2
Memory: 2048MB
Uptime: 86400 seconds

View cluster status

$ pve-cluster

pve-node2       online  8.7%    32.1%   604800

Security Considerations

Password Security

• Never commit passwords to version control

• Consider using a .env file that's git-ignored:

  # In ~/.zshrc
  source ~/.proxmox.env
  

• For enhanced security, use Proxmox API tokens instead of passwords:

  # Future enhancement - API token support planned
  export PROXMOX_TOKEN_ID="user@realm!token-name"
  export PROXMOX_TOKEN_SECRET="token-secret"
  

Network Security

• The plugin connects via HTTPS (port 8006)
• SSL certificates are not strictly validated (-k flag in curl)
• Ensure your Proxmox server uses proper SSL certificates in production

Troubleshooting

Common Issues

"Error: Please set PROXMOX_HOST, PROXMOX_USER, and PROXMOX_PASSWORD environment variables"

• Solution: Make sure all required environment variables are set in your ~/.zshrc

"Error: Failed to connect to Proxmox server"

• Check network connectivity: curl -k https://your-proxmox-host:8006
• Verify hostname/IP address is correct
• Ensure port 8006 is accessible

"Error: Could not determine node"

• Check your credentials are valid
• Verify user has permission to list nodes
• Set PROXMOX_NODE explicitly if auto-detection fails

Tab completion not working

• Ensure the plugin is properly loaded: which pve-list
• Try reloading your shell: source ~/.zshrc

Debug Mode

For troubleshooting API calls, you can temporarily modify the curl commands to show more verbose output by adding -v flag.
