What an afternoon… for a few days now, I’ve been trying to find out what’s the big announcement from Microsoft and Citrix in the desktop virtualisation hour webcast later today. I was keeping quiet until after the webcast but now the embargo has lifted, Microsoft has issued a press release, and the news is all over the web:

• Coming in Windows Server 2008 R2 service pack 1 (for which there is no date announced, yet) will be the dynamic memory functionality that was in early releases of Hyper-V for Windows Server 2008 R2 but was later pulled from the product.  Also in SP1 will be a new graphics acceleration platform, known as RemoteFX, that is based on desktop-remoting technology that Microsoft obtained in 2008 when it acquired Calista Technologies, allowing for rich media content to be accessed over the remote desktop protocol, enabling users of virtual desktops and applications to receive a rich 3-D, multimedia experience while accessing information remotely..
• Microsoft and Citrix are offering a “Rescue for VMware VDI” promotion, which allows VMware View customers to trade in up to 500 licenses at no additional cost, and the “VDI Kick Start” promotion, which offers new customers a more than 50 percent discount off the estimated retail price.
• There are virtualisation licensing changes too: from July, Windows Client Software Assurance customers will no longer have to buy a separate license to access their Windows operating system in a VDI environment, as virtual desktop access rights now will be a Software Assurance (SA) benefit – effectively, if you have SA, you get Windows on screen, no matter what processor it is running on!  There will also be new roaming usage rights and Windows Client Software Assurance and new Virtual Desktop Access (the new name for VECD) customers will have the right to access their virtual Windows desktop and their Microsoft Office applications hosted on VDI technology on secondary, non-corporate network devices, such as home PCs and kiosks.
• Citrix will ensure that XenDesktop HDX technology will be interoperable with and will extend RemoteFX within 6 months.
• Oh yes, and Windows XP Mode (i.e. Windows Virtual PC) will no longer requires hardware virtualisation technology (although, frankly, I find that piece of news a little less exciting as I’d really like to see Virtual PC replaced by a client-side hypervisor).
