How It Works and When You Need It"},"content":{"rendered":"\n

Short answer:<\/strong> a KVM VPS is a virtual private server that runs as a full virtual machine on KVM, the virtualization built into the Linux kernel. It has its own kernel, its own share of RAM and CPU, and its own virtual disk and network card, so it behaves like a small dedicated server. You can install almost any operating system on it, including Windows, and run software that container-based VPS hosting can’t, such as Docker or kernel-level VPNs.<\/p>\n\n\n\n

systemd-detect-virt and lscpu on one of our KVM VPS: the hypervisor is KVM, with full virtualization.<\/figcaption><\/figure>\n\n\n\n

What KVM is<\/h2>\n\n\n\n

KVM stands for Kernel-based Virtual Machine<\/strong>. It is open-source virtualization that has been part of the mainline Linux kernel since version 2.6.20. It uses the virtualization features built into modern processors (Intel VT or AMD-V) and turns a Linux server into a hypervisor that can run many virtual machines side by side.<\/p>\n\n\n\n

Each virtual machine gets its own virtual hardware: a network card, disks, a graphics adapter and so on. Because the guest sees what looks like a real computer, it can run unmodified Linux or Windows. That is the key difference from container-based VPS hosting.<\/p>\n\n\n\n

KVM VPS vs container VPS (OpenVZ, LXC)<\/h2>\n\n\n\n

Some VPS hosting uses containers instead of virtual machines. Every container on a host shares the host’s Linux kernel, which is efficient but limits what you can do inside it:<\/p>\n\n\n\n

How to check whether your VPS runs on KVM<\/h2>\n\n\n\n

Log in over SSH and run:<\/p>\n\n\n\n

systemd-detect-virt\nlscpu | grep -i hypervisor<\/code><\/pre>\n\n\n\n
On a KVM VPS the first command prints kvm<\/code> and the second shows Hypervisor vendor: KVM<\/code>. A container prints its container type instead, such as openvz<\/code>, lxc<\/code> or docker<\/code>. We checked this on one of our KVM VPS running AlmaLinux 9.<\/p>\n\n\n\n
