## ✅ 7. Potential Issues Check

### Image Availability
- ⚠️ **Action Required**: Verify `ubuntu-22.04-cloud` image exists on all Proxmox nodes
- ⚠️ **Action Required**: Ensure image is accessible from specified storage

### Provider Configuration
- ⚠️ **Action Required**: Verify `proxmox-provider-config` exists in Kubernetes
- ⚠️ **Action Required**: Verify provider credentials are correct

### Network Configuration
- ✅ **All VMs use vmbr0**: Consistent network configuration
- ⚠️ **Action Required**: Verify vmbr0 exists on all Proxmox nodes

### Resource Availability
- ⚠️ **Action Required**: Verify sufficient CPU, memory, and disk on Proxmox nodes

---

## ⚠️ Pre-Deployment Actions Required

### 1. Verify Image Availability
```bash
# On each Proxmox node, verify image exists:
find /var/lib/vz/template/iso -name "ubuntu-22.04-cloud.img"
# Or check storage:
pvesm list <storage-name> | grep ubuntu-22.04-cloud
```

### 2. Verify Provider Configuration
```bash
# In Kubernetes:
kubectl get providerconfig proxmox-provider-config -n crossplane-system
kubectl get secret -n crossplane-system | grep proxmox
```

### 3. Verify Resource Availability
```bash
# Check Proxmox node resources:
pvesh get /nodes/<node>/status
# Check available storage:
pvesm list <storage-name>
```

### 4. Test Deployment
```bash
# Deploy test VM first:
kubectl apply -f examples/production/basic-vm.yaml
# Monitor deployment:
kubectl get proxmoxvm basic-vm-001 -w
# Check logs:
kubectl logs -n crossplane-system -l app=crossplane-provider-proxmox
```
