Complete Guide to Virtualizor:
Managing Your VPS Like a Pro

When you purchase a VPS from Azion Cloud, you get access to Virtualizor — a powerful web-based VPS management panel that gives you full control over your virtual private server. Think of it as the control room for your VPS: you can start, stop, reinstall, monitor, and configure your server from anywhere through your browser.

Most VPS users only use the basics — start and stop. But Virtualizor has dozens of features that can save you time, prevent data loss, and help you diagnose problems faster. This guide covers everything you need to know.

What Is Virtualizor?

Virtualizor is a commercial web-based VPS control panel developed by Softaculous. It supports multiple virtualization technologies including KVM (Kernel-based Virtual Machine), OpenVZ, Xen, and LXC. Azion Cloud uses KVM virtualization for all VPS plans, which gives you a truly isolated virtual machine with dedicated resources.

KVM vs Other Virtualization

Understanding why KVM matters:

Feature	KVM (What Azion Uses)	OpenVZ
Isolation	Full hardware-level isolation	Shared kernel with host
Custom Kernel	Yes — run any kernel version	No — stuck with host kernel
OS Support	Any Linux distro, Windows, FreeBSD	Linux only
Resource Guarantee	100% dedicated CPU/RAM	Shared, can be oversold
Docker Support	Full native support	Limited or broken
Performance	Near bare-metal	Slightly faster but less isolated

With KVM, your VPS behaves exactly like a physical server. You get your own kernel, your own network stack, and guaranteed resources that can't be stolen by other users on the same machine.

Accessing the Virtualizor Panel

After purchasing a VPS from Azion Cloud, you'll receive login credentials via email. The panel is accessible at your server's IP address on port 4083 (HTTPS):

https://your-server-ip:4083

Log in with the credentials provided. You'll see your VPS listed on the dashboard with its current status, IP address, and resource usage summary.

Dashboard Overview

The Virtualizor dashboard shows you everything at a glance:

• Server Status: Whether your VPS is running, stopped, or suspended.
• Resource Usage: Current CPU utilization, RAM usage, disk I/O, and network bandwidth.
• IP Address: Your server's primary IPv4 address and any additional IPs.
• OS Information: The currently installed operating system and its version.
• Uptime: How long since the last reboot.

Essential Operations

Starting, Stopping, and Restarting

The power controls are at the top of your VPS management page:

• Start: Boots your VPS from a powered-off state.
• Shutdown: Sends a graceful shutdown signal to the OS. This is the safest way to stop your server — it lets running processes save their state.
• Reboot: Gracefully restarts the VPS. Use this after installing system updates or changing kernel parameters.
• Power Off: Forcefully cuts power to the VPS. Only use this if the server is stuck and won't respond to a graceful shutdown. This is equivalent to pulling the power cable on a physical server — data corruption is possible.

Reinstalling the Operating System

One of Virtualizor's most useful features. You can completely reinstall your VPS with a fresh OS in under 5 minutes:

1. Go to Manage VPS → Reinstall
2. Choose your OS from the available templates:
   • Ubuntu 22.04 / 24.04 LTS — Most popular choice. Huge community, excellent documentation. Best for beginners.
   • Debian 11 / 12 — Ultra-stable, minimal bloat. Preferred by experienced sysadmins.
   • CentOS Stream / AlmaLinux 9 — Enterprise-grade stability. Good for production workloads.
   • Rocky Linux 9 — CentOS replacement, binary-compatible with RHEL.
3. Set a new root password
4. Click Reinstall

Warning: Reinstalling erases ALL data on the VPS. Always download your backups first. If you're running game servers through Pterodactyl, make sure to back up your server files through the Pterodactyl panel before reinstalling.

VNC Console Access

The VNC (Virtual Network Computing) console gives you direct screen access to your VPS — it's like sitting in front of the physical monitor. This is essential when:

• SSH is broken or you've locked yourself out with a firewall misconfiguration
• Your VPS is in single-user/rescue mode
• You need to troubleshoot boot failures
• You're installing an OS that requires a graphical installer

Access it from Manage VPS → VNC. The noVNC web client opens directly in your browser — no additional software needed.

Resource Monitoring

Real-Time Graphs

Virtualizor provides detailed resource graphs for your VPS:

• CPU Usage: Shows CPU utilization over time. If you're consistently hitting 80-100%, you may need to upgrade your plan or optimize your applications.
• RAM Usage: Tracks memory allocation. For game servers, this is crucial — if your Minecraft server keeps hitting the RAM limit, it'll start lagging. See our RAM guide.
• Disk I/O: Read and write speeds. NVMe SSDs on Azion Cloud provide extremely fast I/O, but if you see sustained high I/O, it might indicate excessive logging or world save operations.
• Network: Incoming and outgoing bandwidth. Useful for detecting DDoS attacks (sudden bandwidth spikes) or identifying when your server is transferring large amounts of data.

Understanding Resource Alerts

Here's how to interpret common resource patterns:

Pattern	What It Means	Solution
CPU constantly at 100%	Application is CPU-bound	Optimize code, upgrade plan, or use lighter software
RAM slowly increasing	Possible memory leak	Restart the application, check for leaks
Sudden bandwidth spike	Possible DDoS attack	Enable DDoS protection
High disk I/O	Heavy read/write operations	Optimize database queries, reduce logging
RAM at 95%+ constantly	Server needs more memory	Upgrade RAM or optimize applications

Networking Configuration

IP Address Management

Your VPS comes with a dedicated Indian IPv4 address. In Virtualizor, you can view your IP configuration under Manage VPS → IPs. This shows:

• Primary IPv4 address
• Subnet mask and gateway
• DNS servers (typically Cloudflare 1.1.1.1 and Google 8.8.8.8)

Reverse DNS (rDNS)

If you're running a mail server or any service that requires proper DNS identification, you can set a reverse DNS record through the panel. Go to Manage VPS → IPs and edit the rDNS field for your IP address.

Hostname

Set your VPS hostname from Manage VPS → Hostname. Use a fully qualified domain name (FQDN) like server1.yourdomain.com for best compatibility with services that check hostname resolution.

Backup and Snapshots

Taking Snapshots

Snapshots capture the exact state of your VPS at a specific moment — disk, memory, and configuration. They're invaluable before making major changes:

• Before OS upgrades: Take a snapshot before running apt upgrade on a production system.
• Before installing new software: If the installation breaks something, you can restore instantly.
• Before configuration changes: Modifying /etc/nginx/nginx.conf or firewall rules? Snapshot first.

To create a snapshot: Manage VPS → Snapshots → Create Snapshot. Name it descriptively (e.g., "before-nginx-update-jul25").

To restore: Select the snapshot and click Restore. The VPS will be rolled back to exactly the state it was in when the snapshot was taken.

Backup Best Practices

• Take snapshots before every major change
• Don't rely solely on snapshots — also download critical data to your local machine
• For game servers using Pterodactyl, use Pterodactyl's built-in backup system for game data, and Virtualizor snapshots for OS-level changes
• Keep at least one recent snapshot at all times

Common Use Cases on Azion Cloud

Running Game Servers with Pterodactyl

Many Azion Cloud VPS customers use their VPS to run Pterodactyl Panel for managing multiple game servers. The workflow is:

1. Purchase a VPS with sufficient resources
2. Install Pterodactyl Panel (Wings) on the VPS
3. Create game servers through Pterodactyl (Minecraft, FiveM, Palworld, etc.)
4. Use Virtualizor for OS-level management (updates, reboots, snapshots)
5. Use Pterodactyl for game-level management (server configs, mods, backups)

This gives you a two-layer management system: Virtualizor handles the infrastructure, Pterodactyl handles the games.

Running a Discord Bot 24/7

A VPS is perfect for hosting Discord bots that need to run around the clock. Use Virtualizor to monitor your VPS resources and ensure your bot isn't consuming too much RAM. Set up a process manager like PM2 (Node.js) or systemd to auto-restart your bot if it crashes.

Web Hosting and Development

Deploy websites, APIs, and web applications on your VPS. Use Virtualizor to monitor traffic patterns and scale resources as your site grows. The NVMe storage on Azion Cloud's VPS plans ensures fast page loads for visitors across India.

Troubleshooting

Can't SSH into VPS

1. Check if the VPS is running in Virtualizor (might be stopped)
2. Use VNC console to access the server directly
3. Check if you've blocked SSH with a firewall rule (iptables -L via VNC)
4. Verify you're using the correct IP, port, and credentials
5. Try a fresh OS reinstall if nothing works

VPS Running Slow

1. Check resource graphs for CPU/RAM bottlenecks
2. Run top or htop via SSH to identify resource-hungry processes
3. Check disk usage with df -h — full disk causes severe slowdowns
4. Review security settings — crypto miners from compromised accounts cause high CPU
5. Consider upgrading your plan if you've genuinely outgrown the current resources

Server Won't Boot After Update

1. Use VNC console to see boot error messages
2. If a kernel update broke things, try booting an older kernel from GRUB menu
3. Restore a snapshot if you took one before the update
4. As a last resort, reinstall the OS and restore your application data from backups
