When choosing a VPS hosting plan, most people focus on RAM, bandwidth, or price — but one of the most critical elements lies under the hood: the virtualization technology powering your server. At LunarVPS, we offer both KVM and OpenVZ VPS options — because no single approach fits all users.

If you’re serious about performance, control, or running high-risk or resource-hungry projects, it’s essential to understand how KVM vs. OpenVZ works — and which one suits your goals best.

What Is VPS Virtualization?

Virtualization is the technology that splits a physical server into multiple virtual servers — giving each user isolated access to compute resources. The two most widely used platforms in VPS hosting today are:

• KVM (Kernel-based Virtual Machine)
  
• OpenVZ (Open Virtuozzo)
  

Both are built on Linux but serve very different use cases. Let’s break down how they compare.

KVM VPS Hosting: Full Virtualization & Total Control

KVM (Kernel-based Virtual Machine) is a full virtualization solution where each VPS runs its own independent kernel, like a separate physical machine.

Key Advantages of KVM:

• True isolation – your resources aren’t shared with others
  
• Custom OS support – install Linux, Windows, BSD, or custom kernels
  
• Root-level control – perfect for advanced configurations
  
• High performance under load – best for real-time apps, game servers, crypto, and proxies
  
• Better security – isolated memory and kernel access
  

With LunarVPS, our KVM plans are SSD-powered, use RAID-10 storage, and offer 1Gbps+ unmetered bandwidth, making them ideal for clients who need raw power with privacy — especially those deploying offshore or adult content.

OpenVZ VPS Hosting: Lightweight & Budget-Friendly

OpenVZ uses container-based virtualization where multiple users share the same kernel. It’s more like a partitioned shared server, but with better resource control.

Key Advantages of OpenVZ:

• Lower cost – perfect for startups, learners, and basic sites
  
• Faster deployment – launch in seconds with preloaded OS templates
  
• Efficient resource usage – no kernel overhead
  
• Simpler upgrades – scale CPU or RAM as needed
  

However, since OpenVZ containers share a host kernel, you can’t install custom operating systems or perform kernel-level tasks. It’s best for lightweight web hosting, blogs, development environments, or email servers that don’t require deep system access.

KVM vs. OpenVZ – Side-by-Side Comparison

Feature	KVM	OpenVZ

Custom OS Support	✅ Yes	❌ No
Root Access	✅ Full	✅ Limited
Kernel Control	✅ Yes	❌ Shared Host Kernel
Performance	🔥 High	⚡ Medium
Resource Isolation	✅ Strong	⚠️ Shared under stress
Best For	Advanced users, apps, crypto, proxies	Basic sites, blogs, dev tests

Which Should You Choose?

If you’re hosting:

• Crypto apps, VPNs, or Tor nodes
  
• Adult content, high-traffic affiliate landing pages
  
• Gaming, scraping, or file hosting
  

Go with a KVM VPS — it gives you isolation, root control, and long-term performance.

If you’re testing a small site, launching a WordPress blog, or just need a cheap offshore server for light usage — OpenVZ VPS is a great starting point.

LunarVPS offers both options across our Netherlands and Switzerland data centers, with the ability to upgrade anytime as your project grows.
