About Open Virtualization Alliance
KVM (Kernel-based Virtual Machine) is the leading open source complete virtualization solution on x86 hardware and it supports all major operating systems including Linux and Windows. KVM enables organizations to be agile by providing robust flexibility and scalability that fit their specific business demands. KVM converts the Linux kernel into a bare metal hypervisor and it leverages the advanced features of Intel VT-X and AMD-V x86 hardware, thus delivering unsurpassed performance levels. In addition, KVM incorporates Linux security features including SELinux(Security-Enhanced Linux) developed by the US Security Agency to add access controls, multi-level and multi-category security as well as policy enforcement. As a result, organizations are protected from compromised virtual machines which are isolated and cannot be accessed by any other processes.
Much like Linux itself, server virtualization technology is following the now-familiar trajectory toward open and standard implementations. Just as industry-standard x86 processors have steadily replaced proprietary processors, and Linux has replaced many proprietary operating systems, so too open source KVM hypervisor technology now competes directly with other virtualization solutions. This progress has been aided by the fact that industry- standard x86 processors and systems have grown increasingly more powerful, in terms of processing, memory, and I/O—and now represent attractive shared resources. In addition, the integration of key virtualization technology at the processor level by both Intel (Intel® VT) and AMD (AMD-V) has enabled virtualization to be deeply integrated at the Linux kernel level, yielding significant benefits in terms of performance, scalability, and security.
