# Proxmox Troubleshooting Guide

## Common Issues and Solutions

### Provider Not Connecting

#### Symptoms
- Provider logs show connection errors
- ProviderConfig status is not Ready
- VM creation fails with connection errors

#### Solutions

1. **Verify Endpoint**:
   ```bash
   curl -k https://your-proxmox:8006/api2/json/version
   ```

2. **Check Credentials**:
   ```bash
   kubectl get secret proxmox-credentials -n crossplane-system -o yaml
   ```

3. **Test Authentication**:
   ```bash
   curl -k -X POST \
     -d "username=root@pam&password=your-password" \
     https://your-proxmox:8006/api2/json/access/ticket
   ```

4. **Check Provider Logs**:
   ```bash
   kubectl logs -n crossplane-system -l app=crossplane-provider-proxmox --tail=100
   ```

### VM Creation Fails

#### Symptoms
- VM resource stuck in Creating state
- Error messages in VM resource status
- No VM appears in Proxmox

#### Solutions

1. **Check VM Resource**:
   ```bash
   kubectl describe proxmoxvm <vm-name>
   ```

2. **Verify Site Configuration**:
   - Site must exist in ProviderConfig
   - Endpoint must be reachable
   - Node name must match actual Proxmox node

3. **Check Proxmox Resources**:
   - Storage pool must exist
   - Network bridge must exist
   - OS template must exist

4. **Check Proxmox Logs**:
   - Log into Proxmox Web UI
   - Check System Log
   - Review task history

### VM Status Not Updating

#### Symptoms
- VM status remains unknown
- IP address not populated
- State not reflecting actual VM state

#### Solutions

1. **Check Provider Connectivity**:
   ```bash
   kubectl logs -n crossplane-system -l app=crossplane-provider-proxmox | grep -i error
   ```

2. **Verify VM Exists in Proxmox**:
   - Check Proxmox Web UI
   - Verify VM ID matches

3. **Check Reconciliation**:
   ```bash
   kubectl get proxmoxvm <vm-name> -o yaml | grep -A 5 conditions
   ```

### Storage Issues

#### Symptoms
- VM creation fails with storage errors
- "Storage not found" errors
- Insufficient storage errors

#### Solutions

1. **List Available Storage**:
   ```bash
   # Via Proxmox API
   curl -k -H "Authorization: PVEAuthCookie=TOKEN" \
     https://your-proxmox:8006/api2/json/storage
   ```

2. **Check Storage Capacity**:
   - Log into Proxmox Web UI
   - Check Storage section
   - Verify available space

3. **Update Storage Name**:
   - Verify actual storage pool name
   - Update VM manifest if needed

### Network Issues

#### Symptoms
- VM created but no network connectivity
- IP address not assigned
- Network bridge errors

#### Solutions

1. **Verify Network Bridge**:
   ```bash
   # Via Proxmox API
   curl -k -H "Authorization: PVEAuthCookie=TOKEN" \
     https://your-proxmox:8006/api2/json/nodes/ML110-01/network
   ```

2. **Check Network Configuration**:
   - Verify bridge name in VM manifest
   - Check bridge exists on node
   - Verify bridge is active

3. **Check DHCP**:
   - Verify DHCP server is running
   - Check network configuration
   - Review VM network settings

### Authentication Failures

#### Symptoms
- 401 Unauthorized errors
- Authentication failed messages
- Token/ticket errors

#### Solutions

1. **Verify Credentials**:
   - Check username format: `user@realm`
   - Verify password is correct
   - Check token format if using tokens

2. **Test Authentication**:
   ```bash
   # Password auth
   curl -k -X POST \
     -d "username=root@pam&password=your-password" \
     https://your-proxmox:8006/api2/json/access/ticket
   
   # Token auth
   curl -k -H "Authorization: PVEAuthCookie=TOKEN" \
     https://your-proxmox:8006/api2/json/version
   ```

3. **Check Permissions**:
   - Verify user has VM creation permissions
   - Check token permissions
   - Review Proxmox user roles

### Provider Pod Issues

#### Symptoms
- Provider pod not starting
- Provider pod crashing
- Provider pod in Error state

#### Solutions

1. **Check Pod Status**:
   ```bash
   kubectl get pods -n crossplane-system -l app=crossplane-provider-proxmox
   kubectl describe pod -n crossplane-system -l app=crossplane-provider-proxmox
   ```

2. **Check Pod Logs**:
   ```bash
   kubectl logs -n crossplane-system -l app=crossplane-provider-proxmox --tail=100
   ```

3. **Check Image**:
   ```bash
   kubectl get deployment -n crossplane-system crossplane-provider-proxmox -o yaml | grep image
   ```

4. **Verify Resources**:
   ```bash
   kubectl get deployment -n crossplane-system crossplane-provider-proxmox -o yaml | grep -A 5 resources
   ```

## Diagnostic Commands

### Check Provider Health
```bash
# Provider status
kubectl get deployment -n crossplane-system crossplane-provider-proxmox

# Provider logs
kubectl logs -n crossplane-system -l app=crossplane-provider-proxmox --tail=50

# Provider metrics
kubectl port-forward -n crossplane-system deployment/crossplane-provider-proxmox 8080:8080
curl http://localhost:8080/metrics
```

### Check VM Resources
```bash
# List all VMs
kubectl get proxmoxvm

# Get VM details
kubectl get proxmoxvm <vm-name> -o yaml

# Check VM events
kubectl describe proxmoxvm <vm-name>
```

### Check ProviderConfig
```bash
# List ProviderConfigs
kubectl get providerconfig

# Get ProviderConfig details
kubectl get providerconfig proxmox-provider-config -o yaml

# Check ProviderConfig status
kubectl describe providerconfig proxmox-provider-config
```

## Escalation Procedures

### Level 1: Basic Troubleshooting
1. Check provider logs
2. Verify credentials
3. Test connectivity
4. Review VM resource status

### Level 2: Advanced Troubleshooting
1. Check Proxmox Web UI
2. Review Proxmox logs
3. Verify network connectivity
4. Check resource availability

### Level 3: Infrastructure Issues
1. Contact Proxmox administrator
2. Check infrastructure status
3. Review network configuration
4. Verify DNS resolution

## Prevention

1. **Regular Monitoring**: Set up alerts for provider health
