System Center Virtual Machine Manager (or SCVMM or even VMM for short) 2008 is Microsoft’s management tool for Hyper-V and Virtual Server 2005, with added ability to even manage VMware ESX servers. After installing VMM 2008 and connecting it to Hyper-V hosts, if these Hyper-V hosts do not have two updates installed on them, SCVMM 2008 server will report your hosts as “Needs Attention”, and the sub-status for Virtualization Service Version will show as “Upgrade Available”.
The nasty thing about this is that these updates are not listed in the Windows Update list of available updates, and you must manually download and install them.

Download #2: BITS Update (KB956774)

Note: This patch is not available for download like the previous one. You must request it through the provided link, and you’ll receive a confirmation e-mail containing the download link and a password for the zipped file.
Important note: Both hotfixes require a reboot, so be sure to properly plan for installing them with minimum interruption to running virtual machines.
After installing these updates, you must refresh the status of the Hyper-V hosts. Once finished, the status of the Hyper-V hosts are changed to normal.
Download and install the following updates on all of your Hyper-V hosts:
