Kernel-based Virtual Machine (KVM) is a free and open-source virtualization module in the Linux kernel that allows the kernel to function as a hypervisor. It was merged into the mainline Linux kernel in version 2.6.20, which was released on February 5, 2007. [ 1 ]
Two types of virtualization are supported: container-based with LXC (starting from version 4.0 replacing OpenVZ used in version up to 3.4, included [10]), and full virtualization with KVM. [11] It includes a web-based management interface. [12] [13] There is also a mobile application available for controlling PVE environments. [14]
KVM (Kernel-based Virtual Machine) is a FreeBSD and Linux kernel module that allows a user space program access to the hardware virtualization features of various processors, with which QEMU can offer virtualization for x86, PowerPC, and S/390 guests. When the target architecture is the same as the host architecture, QEMU can make use of KVM ...
A computer on which a hypervisor runs one or more virtual machines is called a host machine, and each virtual machine is called a guest machine. The hypervisor presents the guest operating systems with a virtual operating platform and manages the execution of the guest operating systems.
Virtualization began in the 1960s with IBM CP/CMS. [1] The control program CP provided each user with a simulated stand-alone System/360 computer. In hardware virtualization, the host machine is the machine that is used by the virtualization and the guest machine is the virtual machine.
Full-system virtualization (Processor Core ISA + Hardware + External connections) Early embedded software development and integration (from driver to application), Multi-core software debugging and optimization Depending on the system characteristics and the software itself, ranges from faster than real time to slow [citation needed].

KVM switch (keyboard, video, and mouse switch), originally a hardware device for controlling multiple computers, now also used to refer to software tools used to achieve similar functionality (for example Synergy and various more fully open-source equivalents)
KVM, a virtualization module integrated into the Linux kernel, is released. January 15, 2007 InnoTek releases VirtualBox Open Source Edition (OSE), the first professional PC virtualization solution released as open source under the GNU General Public License . It includes some code from the QEMU project.
