What is VPS KVM? (and when to choose it)

### What is KVM?

KVM (Kernel‑based Virtual Machine) is a full virtualization technology built into the Linux kernel. Unlike lightweight container systems that share a single kernel, KVM creates a completely isolated virtual machine with its own virtual hardware and operating system. Each KVM VPS at IllusionCloud runs its own kernel and provides true virtualization of CPU, memory, storage and networking.

### Why choose a KVM VPS?

- **Full isolation:** KVM offers better isolation between guests. You can load custom kernel modules and run a wide variety of operating systems, including Windows Server or FreeBSD.
- **Root access & customisation:** Each VPS gives you full root access, allowing you to install software, configure system settings and manage firewall rules.
- **Performance:** With dedicated CPU time slices and NVMe SSD storage, KVM VPSs deliver high performance suitable for production applications, game servers or development environments.
- **Security:** The hypervisor enforces strong separation between guests. IllusionCloud complements this with anti‑DDoS protection and 99.9 % uptime SLA.

### When to choose KVM

Choose a KVM VPS if you need a flexible environment where you control the operating system and kernel, or if you require features like Windows or custom modules that cannot run in container‑based offerings. If your workload is less demanding and you prefer faster provisioning with lower overhead, consider the LXC container plans instead.
