Intel virtualisation: how VT-x, KVM and QEMU work together

VT-x is name of CPU virtualisation technology by Intel. KVM is component of Linux kernel which makes use of VT-x. And QEMU is a user-space application which allows users to create virtual machines. QEMU makes use of KVM to achieve efficient virtualisation. In this article we will talk about how these three technologies work together. Don’t expect an in-depth exposition about all aspects here, although in future, I might follow this up with more focused posts about some specific parts.
