What is KVM networking?

Kernel-based Virtual Machine (KVM) is an open source virtualization technology built into Linux®. Specifically, KVM lets you turn Linux into a hypervisor that allows a host machine to run multiple, isolated virtual environments called guests or virtual machines (VMs). KVM is part of Linux.

Routing allows multiple networks to communicate independently and yet remain separate, whereas bridging connects two separate networks as if they were a single network.

Is KVM Type 1 or Type 2?

Basically, KVM is a type-2 hypervisor (installed on top of another OS, in this case some flavor of Linux). It runs, however, like a type-1 hypervisor and can provide the power and functionality of even the most complex and powerful type-1 hypervisors, depending on the tools that are used with the KVM package itself.

Is KVM safe?

While many government IT security administrators have started deploying KVMs to address inefficiencies of non-switched secured desktops, not all KVMs are highly secure, making them vulnerable to malicious use through: USB peripheral vulnerabilities.

Is KVM free?

KVM is made up of a loadable kernel module (kvm. ko) and a processor-specific module for Intel or AMD used to host Linux and Windows images on virtual machines with the QEMU userspace. KVM is available as a free open source software download, but there are commercial support options from vendors like Red Hat or Oracle.
