An private update has been released for users experiencing the following issues:
You cannot connect to a virtual machine when the Windows Server 2008 Hyper-V VMMS certificate has expired Cannot connect to the virtual machine because the authentication certificate is expired or invalid. Would you like to try connecting again? 'VMName' failed to initialize. Could not initialize machine remoting system. Error: ‘Unspecified error’ (0x80004005). Could not find a usable certificate. Error: ‘Unspecified error’ (0x80004005).

And then today I noticed this posted on Ben Armstrong's blog:
Management Operating System This is a new term that we are introducing in Windows Server 2008 R2. We have been struggling without a good term here – as with Virtual PC / Virtual Server we had a nice set of terms where we could talk about the physical computer / virtual machine and the host operating system / guest operating system. However this became muddier with Hyper-V – because we no longer really have a host operating system, and all operating systems run on top of the hypervisor. Most people have been just using the term “Parent” or “Parent partition” to refer to what we used to call the host operating system – but this is not really architecturally correct. Unfortunately the architecturally correct terms are – frankly – hideous; they are the “parent partition guest operating system” and the “child partition guest operating system”. Yuck. So after a lot of thought we decided to call the “parent partition guest operating system” the “Management operating system” as this is the operating system you use to manage your virtual machines, and “guest operating system” will be reserved to mean the operating system running inside virtual machines.
