Microsoft System Center Virtual Machine Manager

Confused as to why your Hyper-V host is showing:
Host: Needs Attention

VMM requires an important update from Hyper-V and a critical update from Background Intelligent Transfer Service (BITS). Without these updates, VMM hosts display in the state of “Needs Attention” and the virtualization service version as “Upgrade available”. (Thanks to Matt Briggs for this info…)

I’ve seen this mentioned in a few places and had to deal with this in my environment as well – luckily the resolution is quite simple. You will need to download and install the following two patches on the Hyper-V host.

Hyper-V Update for Windows Server 2008 x64 Edition: KB 956589

Background Intelligent Transfer Service (BITS) update: KB 956774
