KB 971677 discusses an issue when a Hyper-V differencing disk that you create in Windows Server 2008 R2 cannot be used in Windows Server 2008.
Note: you need to click in "request hotfix" on top of KB page to request the hotfix for this specific error.
A server error occurred while you try to import the virtual machine. Failed to import the virtual machine from import directory ''. Failed to add device 'Microsoft Virtual Hard Disk'. Cannot open attachment '\Filename.vhd'. Error: 'The file or directory is corrupted and unreadable.'Cannot get information for attachment '\Filename.vhd'.
A Read Only Domain Controller (RODC) can only be used as a Host if it was already a Host prior to being promoted. If a RODC needs to be used as a Host and was not previously managed by SCVMM, it will have to be demoted to a member server and made a managed Host prior to promotion back to RODC. IMPORTANT: Although a Read Only Domain Controller can be used as Host in SCVMM, this is not the recommended usage of a Read Only Domain Controller.

If you’ve this problem, please let me know if that solves your problem.
I already upgrade most of my environment to R2 version of Hyper-V including SCVMM 2008 R2. I waited for the supported version of HP firmware “ver. 8.60”/software/Drivers “ver.8.30” for HP DL380G5 servers, you can find them here, after applying the new firmware and drivers everything worked fine.
Directly from CODEPLEX this free tool is a secure, multi tab terminal services/remote desktop client that uses Terminal Services ActiveX Client (mstscax.dll). CODEPLEX started this project from the need of controlling multiple connections simultaneously. It is a complete replacement for the Windows mstsc.exe (Terminal Services) client.
Terminals allows storing multiple remote connections of varying types (RDP, VNC, VMRC, Telnet, SSH1, SSH2, ICA Citrix, RAS and HTTP) you also have the possibility of arranging them by tags or in groups. Using Active Directory or scanning a range of IP addresses allows you to create new connections.
Terminals allow you to import RDP, vRD or MuRD files.

vSphere Videos/Demos: Check Mike Laverick’s extremely valuable free vSphere videos. If you wish to learn more about vSphere these resources will help you with that. From basic steps to more complex scenarios, Mike does a pretty good job on his demonstrations. So there you go, for free you can get excellent content that you normally would have to pay for.
The book: The main reason I put these videos together is as free supplement to my soon-to-be-released book on vSphere4, and to give people who by the book - a live on screen demo of the configuration - although you don’t have to buy the book to watch these videos. I find it’s often its easier to quickly show something than it is to do a 100 screen grabs and loads of text - but in the same instance videos don’t allow for long and details discussions of best practises and possible configurations. So if you want detail, get the book - but if you want quick high-level views of things - the videos slot into that…
