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".
Are you able to identify precisely which processes are sucking up resources and slowing down your servers? Can you do this equally well over VM guests that VMotion?
OpManager also allows admins to remotely shut down problem-causing processes. With over 500 built-in monitors & 70 deep VMware metrics reported on, OpManager is one of the most comprehensive fault & performance management solutions available today for entire server infrastructure - both physical and virtual.
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.
