Congratulations Xen developers!


We’re pleased to announce the official release of Xen 3.1!

This represents a major milestone in the Xen project containing performance and stability enhancements, additional features for all architectures, and a brand new management API. Highlights of this release include:

* XenAPI 1.0 support
– 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;
* Dynamic memory control for HVM guests;
* 32-on-64 PV guest support (run PAE PV VMs on a 64-bit Xen!); and
* Blktap copy-on-write disk support.
