While the Kernel-based Vitual Machine
, and VirtualBox
have been generating most of the attention as of late when it comes to Linux virtualization, Xen is still alive and kicking. In fact, the Xen development team just announced the release of Xen 3.4.0.
The key features introduced in Xen 3.4.0 include device pass-through improvements (notably with client devices), RAS features via CPU and memory off-lining, better power management, support for the Viridian (Hyper-V) enlightenment interface, and many x86 and IA64 enhancements and fixes. The better power management comes in the way of improved frequency/voltage controls and deep-sleep. Xen's scheduler and timers have also been optimized for peak power savings, with the emphasis that has been going on for reducing server power consumption.
