Recent releases
- 31 May 2009 21:32
Changes: Device passthrough improvements, with particular emphasis on support for client devices. RAS features: CPU and memory offlining. Power management: improved frequency/voltage controls and deep-sleep support. Scheduler and timers are optimized for peak power savings. Support for the Viridian (Hyper-V) enlightenment interface. Many other x86 and ia64 enhancements and fixes.
- 13 Jan 2009 02:06
Changes: This release adds power management (P & C states) in the hypervisor, PVSCSI drivers, and HVM emulation domains. It has improved paravirtualization, device passthrough, hardware-assisted paging, HVM framebuffer, and shadow pagetable performance. It has improved safety of domain transfer across systems with different CPU models. There are assorted bugfixes and other minor enhancements.
- 15 Aug 2008 06:37
Changes: New features include Xen Security Modules (XSM), ACPI S3 suspend-to-RAM support for the host system, preliminary PCI pass-through support (using appropriate Intel or AMD I/O-virtualization hardware), and preliminary support for a wider range of bootloaders in fully virtualized (HVM) guests, using full emulation of x86 real mode. Emulation of standard (non-super) VGA modes for HVM guests was made faster. Configurable timer modes were added for HVM guests, depending on how the guest OS manages time-keeping.
- 10 Nov 2007 12:16
Changes: This release contains performance and stability enhancements, additional features for all architectures, and a brand new management API. XenAPI 1.0 was introduced, with XML configuration files for virtual machines, VM life-cycle management operations, and secure on- or off-box XML-RPC with bindings for many languages. Preliminary save/restore/migrate support for HVM (e.g. Windows) VMs was added. Dynamic memory control for HVM guests was introduced. 32-on-64 PV guest support was added. Blktap copy-on-write disk support was introduced. Many bugs were fixed.

Hi,
I am hosting free freeshell service at http://zues.dyndns.org. Currently due to security issue we turn on hold for now [been offline for almost 2 months now ;)]. At moment building hold new shell enviroment base on Xen technology. It great security features and I just loving it.. I hope will see continue works on upcoming kernels, INTERGRATED as default!! Part I love about Xen is that some of my enhance kernel patches still working without problem.
Thanks. It's cool.
