The problem is that its not ready yet so if you trial SP1 in this configuration (ie: with Windows Server x64, an AMD proc that supports AMD-V and Virtual Server R2 x64 SP1) then make sure you switch off the AMD-V support in each VM first until we release the hotfix. The connect website should now have an updated piece of information to reflect this fact.
