What This Skill Does

REST API client for managing Proxmox VE clusters, VMs, LXC containers, snapshots, storage, backups, and tasks via curl commands. Requires an API token or credentials file for authentication.

Replaces manual Proxmox web UI navigation by exposing all cluster management operations through a single API-driven CLI.

When to Use It

List all VMs and LXC containers across a Proxmox cluster
Start, stop, or restart a specific VM or container
Create and manage VM snapshots before system updates
Check node status and resource usage (CPU, memory)
View recent cluster tasks and task logs for troubleshooting
Trigger on-demand backups of VMs to a specified storage

Install

$ openclaw skills install @weird-aftertaste/proxmox

Proxmox VE Management

Configuration

Set environment variables or store in ~/.proxmox-credentials:

# Option 1: API Token (recommended)
export PROXMOX_HOST="https://192.168.1.100:8006"
export PROXMOX_TOKEN_ID="user@pam!tokenname"
export PROXMOX_TOKEN_SECRET="xxxxxxxx-xxxx-xxxx-xxxx-xxxxxxxxxxxx"

# Option 2: Credentials file
cat > ~/.proxmox-credentials << 'EOF'
PROXMOX_HOST=https://192.168.1.100:8006
PROXMOX_TOKEN_ID=user@pam!monitoring
PROXMOX_TOKEN_SECRET=your-token-secret
EOF
chmod 600 ~/.proxmox-credentials

Create API token in Proxmox: Datacenter → Permissions → API Tokens → Add

CLI Usage

# Load credentials
source ~/.proxmox-credentials 2>/dev/null

# Auth header for API token
AUTH="Authorization: PVEAPIToken=$PROXMOX_TOKEN_ID=$PROXMOX_TOKEN_SECRET"

Common Operations

Cluster & Nodes

# Cluster status
curl -ks -H "$AUTH" "$PROXMOX_HOST/api2/json/cluster/status" | jq

# List nodes
curl -ks -H "$AUTH" "$PROXMOX_HOST/api2/json/nodes" | jq '.data[] | {node, status, cpu, mem: (.mem/.maxmem*100|round)}'

# Node status
curl -ks -H "$AUTH" "$PROXMOX_HOST/api2/json/nodes/{node}/status" | jq

List VMs & Containers

# All VMs on a node
curl -ks -H "$AUTH" "$PROXMOX_HOST/api2/json/nodes/{node}/qemu" | jq '.data[] | {vmid, name, status, mem: .mem, cpu: (.cpu*100|round)}'

# All LXC containers on a node
curl -ks -H "$AUTH" "$PROXMOX_HOST/api2/json/nodes/{node}/lxc" | jq '.data[] | {vmid, name, status}'

# Cluster-wide resources
curl -ks -H "$AUTH" "$PROXMOX_HOST/api2/json/cluster/resources?type=vm" | jq '.data[] | {node, vmid, name, type, status}'

VM/Container Control

# Start VM
curl -ks -X POST -H "$AUTH" "$PROXMOX_HOST/api2/json/nodes/{node}/qemu/{vmid}/status/start"

# Stop VM
curl -ks -X POST -H "$AUTH" "$PROXMOX_HOST/api2/json/nodes/{node}/qemu/{vmid}/status/stop"

# Shutdown VM (graceful)
curl -ks -X POST -H "$AUTH" "$PROXMOX_HOST/api2/json/nodes/{node}/qemu/{vmid}/status/shutdown"

# Reboot VM
curl -ks -X POST -H "$AUTH" "$PROXMOX_HOST/api2/json/nodes/{node}/qemu/{vmid}/status/reboot"

# Same for LXC: replace /qemu/ with /lxc/

Snapshots

# List snapshots
curl -ks -H "$AUTH" "$PROXMOX_HOST/api2/json/nodes/{node}/qemu/{vmid}/snapshot" | jq

# Create snapshot
curl -ks -X POST -H "$AUTH" "$PROXMOX_HOST/api2/json/nodes/{node}/qemu/{vmid}/snapshot" \
  -d "snapname=snap1" -d "description=Before update"

# Rollback
curl -ks -X POST -H "$AUTH" "$PROXMOX_HOST/api2/json/nodes/{node}/qemu/{vmid}/snapshot/{snapname}/rollback"

# Delete snapshot
curl -ks -X DELETE -H "$AUTH" "$PROXMOX_HOST/api2/json/nodes/{node}/qemu/{vmid}/snapshot/{snapname}"

Tasks & Logs

# Recent tasks
curl -ks -H "$AUTH" "$PROXMOX_HOST/api2/json/nodes/{node}/tasks" | jq '.data[:10] | .[] | {upid, type, status, user}'

# Task log
curl -ks -H "$AUTH" "$PROXMOX_HOST/api2/json/nodes/{node}/tasks/{upid}/log" | jq -r '.data[].t'

Storage

# List storage
curl -ks -H "$AUTH" "$PROXMOX_HOST/api2/json/nodes/{node}/storage" | jq '.data[] | {storage, type, active, used_fraction: (.used/.total*100|round|tostring + "%")}'

# Storage content
curl -ks -H "$AUTH" "$PROXMOX_HOST/api2/json/nodes/{node}/storage/{storage}/content" | jq

Backups

# List backups
curl -ks -H "$AUTH" "$PROXMOX_HOST/api2/json/nodes/{node}/storage/{storage}/content?content=backup" | jq

# Start backup
curl -ks -X POST -H "$AUTH" "$PROXMOX_HOST/api2/json/nodes/{node}/vzdump" \
  -d "vmid={vmid}" -d "storage={storage}" -d "mode=snapshot"

Helper Script

Use scripts/pve.sh for common operations:

./scripts/pve.sh status          # Cluster overview
./scripts/pve.sh vms             # List all VMs
./scripts/pve.sh start {vmid}    # Start VM
./scripts/pve.sh stop {vmid}     # Stop VM

Notes

Replace {node}, {vmid}, {storage}, {snapname} with actual values
API tokens don't need CSRF tokens for POST/PUT/DELETE
Use -k to skip SSL verification for self-signed certs
Task operations return UPID for tracking async jobs
