What is KVM Virtualization? (vs. OpenVZ)

The Virtualization Debate

When you buy a VPS, you are renting a "slice" of a powerful physical server. The technology used to create that slice determines how fast and stable your website will be.

1. KVM (AmanaFlow's Standard)

KVM (Kernel-based Virtual Machine) is built into the Linux kernel itself.

• Isolation: Each VPS has its own kernel, OS, and hardware resources.
• Dedicated RAM: If you pay for 4GB of RAM, that 4GB is yours alone. The host cannot "oversell" it to someone else.
• Customization: You can install any OS, including Windows or custom ISOs.

2. OpenVZ (The Industry's Budget Option)

OpenVZ is like a room in a house. You share the same roof, same air, and same plumbing.

• Shared Kernel: All users share the same underlying operating system core.
• Overselling: Providers often sell 100GB of RAM on a 64GB server, hoping not everyone will use it at once. This leads to slow performance during peak times.

Why KVM is Better for Production

For business websites, E-commerce, or AI apps, KVM is mandatory. If another user on the same physical server has a massive traffic spike, a KVM VPS ensures your site remains fast and unaffected.

The Performance Result

By combining KVM with AMD EPYC processors and NVMe storage, AmanaFlow VPS plans offer the lowest latency and highest throughput in their price class.

FAQ

Q: Can I run Docker on a KVM VPS?
A: Yes! Because you have your own kernel, Docker works perfectly. On OpenVZ, Docker can be very problematic.

Q: Is KVM more expensive to host?
A: Yes, it is more resource-intensive for the hosting provider, which is why some "budget" hosts still use OpenVZ. At AmanaFlow, we believe in performance first.
