A bit of history on KVM (wow, really? I feel like I am writing a paper for grade school):
KVM was developed by a low-profile Israeli startup called Qumranet (pronounced: coom-rah-net), which was formerly known as Comanet. The company was founded in 2005 by Benny Schnaider, Rami Ramir, Moshe Bar and Giora Yaron, and was sold to RedHat in 2008 for $107 million (The KVM software was initially written by Avi Kivity).
KVM is a Type 1 hypervisor. If you are not familiar with hypervisor types, there are 2. I will let you guess what they are called. Type 1 hypervisors run directly on a host to control underlying hardware and manage guest VMs (i.e. KVM, ESXi, Hyper-V). Type 2 hypervisors run on top of a standard operating system (i.e. VirtualBox/VMware Fusion). “KVM is one of the most popular open-source virtualization technologies in use today - the first to be integrated into the vanilla Linux kernel. Both IBM and Red Hat use it as the basis for their Linux virtualization technologies, and it is the most widely used virtualization technology in the OpenStack cloud as well.” Source: http://www.eweek.com/cloud/how-did-kvm-virtualization-get-into-the-linux-kernel.html
