Bink.nu just published a tentative roadmap of what Microsoft is going to release in 2006. Among all products a new Virtual Server major release appears: Virtual Server vNext 2006. I already reported the information without mentioning this name on my September post: Microsoft virtualization roadmap disclosed details Microsoft reported this new version could bring in VMs hot backup based on Volume Shadow Service (VSS) support. It's also possible it will include better virtual video driver to fully support the upcoming Vista new GUI: Aero. Instead it's unsure if the new version will bring 64bit guest OSes or not. No further news are available. Note that Steven Bink reports Windows Hypervisor is scheduled 90 days after codename Longhorn Server release.
