Windows Server 2008 R2 Beta Introduces Live Migration for Hyper-V

Although Microsoft’s roadmap for general availability is still 2010, a public beta version of Server 2008 R2 currently available for Technet subscribers enables live migration for Hyper-V guests. Non subscribers will apparently be able to download the R2 beta from the product’s web page on Friday, January 9th.

This post consists of some quick notes primarily about the new virtualization related features. For more information about all the new enhancements be sure to follow the  links.

From Matt McSpirit’s Virtualboy Blog post Windows Server 2008 R2 and Windows 7 Client Now Available on MSDN/TechNet!

“It’s come round pretty fast I have to say, but Microsoft have announced availability, through MSDN and TechNet (non-MSDN/TechNet subscribers can download them from Friday 9th January), of the beta’s of Windows 7 client, and better still, Windows Server 2008 R2.”

From the Windows Server Division Web Log

Hyper-V in R2 now has Live Migration, allowing IT admins to move VMs across physical hosts with no interruption of service or network connectivity and significant network performance improvements. VMs in Hyper-V for R2 also get greater access to physical resources, namely support for 32 logical processors.”

From the document Top 10 Reasons to Upgrade to Windows Server 2008 R2

“Customers employing System Center Virtual Machine Manager for Hyper-V will also enjoy additional management and orchestration scenarios, including a new VM-oriented Performance and Resource Optimization feature and updated support for managing failover clusters.”

“.. VMs can also add and remove VHD disks without requiring a reboot and also boot from VHD as well.


“Windows Server 2008 R2 contains enhanced Virtual Desktop Integration (VDI) technology, which extends the functionality of Terminal Services to deliver certain business programs to their employee’s remote desktops. With VDI,  programs that Remote Desktop Services sends to a computer are now available on the Start menu right alongside programs that are locally installed. This approach provides improved desktop virtualization and better application virtualization.

Desktop virtualization will benefit from features including improved personalization management, a near-invisible integration of virtualized desktops and applications in Windows 7, better audio and graphics performance, a seriously cool Web access update and more. VDI provides more efficient use of virtualized resources and better integration with local peripheral hardware as well as powerful new virtual management features.”
