KVM is a type of hypervisor that enables, emulates and provides for the creation of virtual machines on operating systems. These machines are built on top of the Linux kernel, using operating systems such as Linux, Ubuntu and Fedora. KVM can be installed on all x86 processors and provide separate instruction set extensions for Intel and AMD processors.
KVM supports multiple different guest operating system images including Linux Kernel, Windows, BSD and Solaris. It also allocates separate virtualized computing resources for each virtual machine such as the processor, storage, memory, etc.
