Linux KVM Virtualization Performance

Michael Larabel writes “For only being a release candidate the Linux 2.6.20 kernel has already generated quite a bit of attention. On top of adding asynchronous SCSI scanning, multi-threaded USB probing, and many driver updates, the Linux 2.6.20 kernel will include a full virtualization solution. Kernel-based Virtual Machine is a GPL software project that has been developed and sponsored by Qumranet. In this article we are offering a brief overview of the Kernel-based Virtual Machine for Linux as well as offering up in-house performance numbers as we compare KVM to other virtualization solutions such as QEMU Accelerator and Xen.”
