The designation does not imply that the application is fully Hyper-V compliant and that all application functionality works optimally. In some cases, the application and or some components in the application may have reduced and or missing functionality while running in a virtual machine running on Hyper-V. The designation also does not imply that the application has passed all the certification requirements while running in a virtual environment. Some test cases in the Certification program may still be executed on a physical machine.
If the application is expected to be impacted when running in a Virtual machine on Hyper-V (or) when Hyper-V features such as Save state, restore etc., are performed, then such impact and workarounds if any must be documented and made available to Customers on demand.
Finally, as more organizations begin wide-spread adoption of virtualization within their environments (including mission critical applications), we'll hopefully see a much larger uptick in virtualization support from ISVs. And perhaps Microsoft's new logo program will help spur the transition even faster. Find out more about the Microsoft Windows Server 2008 R2 Logo Program specifications.
