KVM hypervisor

Contributor(s): Stan Gibilisco

KVM hypervisor is the virtualization layer in Kernel-based Virtual Machine (KVM), a free, open source virtualization architecture for Linux distributions.

A hypervisor is a program that allows multiple operating systems to share a single hardware host. In KVM, the Linux kernel acts as a Type 2 Hypervisor, streamlining management and improving performance in virtualized environments. The hypervisor creates virtual machine (VM) environments and coordinates calls for processor, memory, hard disk, network, and other resources through the host OS. KVM requires a processor with hardware virtualization extensions to connect to the guest OSs.

KVM has been bundled along with the Linux operating system (OS) since 2007 and can be installed along with the Linux kernel. Numerous guest OSs can work with KVM including BSD (Berkeley Software Distribution), Solaris, Windows, Haiku, ReactOS, Plan 9, and the AROS Research OS. In addition, a modified version of QEMU ("Quick Emulator") can use KVM to run Mac OS X.

Excellent article. Question: if one is to instrument a centralized or distributed array of VMs running within the KVM environment, what interfaces are there to pull of performance data or specific generated data for each VM and its apps, and KVM itself? Thx.
