Why should I choose KVM?

We frequently get asked “is KVM the best platform?” or “what advantages does KVM offer over other platforms?” So following on from last weeks post comparing OpenVZ and Xen here’s a quick rundown…

In comparison to OpenVZ and Xen, KVM is about as close to a dedicated server as you are going to get. KVM offers full virtualisation which basically means that each guest virtual machine gets it’s own dedicated, virtual hardware. Another advantage of this type of virtualisation is that since each virtual machine is completely separated, resource hungry virtual machines won’t affect others on the same host. Security is improved too.

KVM supports non-Linux guest virtual machines too, such as FreeBSD, NetBSD and OpenBSD as well as Solaris and derivatives such as OpenIndiana. If you want a particular OS that’s not available in your control panel, let us know and we’ll do our best to get hold of it for you.

From a host’s perspective, it’s nice and lightweight compared to other virtualisation technologies and since it’s all built into the kernel with more upstream support planned and major vendor adoption, it’s going to be around for while yet.

In a nutshell

  • Simplicity – it’s built right into the Linux kernel
  • It’s future proofed – major vendors such as Red Hat and Canonical and have adopted it as their virtualisation platform of choice
  • Your virtual machine gets dedicated resources
  • All virtual servers are properly isolated making KVM a good choice when security is important

If you’ve not tried KVM before and fancy having a play, then you are in luck! We’re running our KVM beta this month to test out KVM under the latest version of SolusVM control panel. You can get more information and sign up here

Edit: The KVM beta is now over!


SolusVM provides you with a suite of tools for managing your KVM through your browser
