Nearly three months in the making, the new Linux kernel (version 2.6.26) announced by Linus Torvalds through a mailing list, boasts read-only bind mounts, “big-iron” KVM ports, USB webcam support, 802.11s mesh WiFi, built-in support for remote kernel debugging, and a host of embedded architecture improvements, among other enhancements.
Among the most significant improvements are changes to the Kernel-based Virtual Machine (KVM) virtualization software, first included in the kernel in February of last year. KVM normally uses the technique of full virtualization, which simulates all the underlying hardware necessary to run a given client system, with the support of virtualization technologies built into AMD and Intel chips. The latest kernel update adds limited support for paravirtualization, a technique that only partially virtualizes the hardware in order to improve performance.
KVM has also, for the first time, been ported to non-x86 hardware platforms Intel IA64 and IBM PPC and S/390, developers said.
