Both myself and Rob have mentioned a few times about the dirty views in Operations Manager after importing the Virtual Machine Manager MP (the SQL view contains ALL virtual computers rather than just servers with SQL installed).
Well good news, it's fixed in the new SP1 release of SCVMM!!!!
Along with Kevin Holman giving an outline of the new SCVMM SP1 he also confirms the problem, that for myself was a show stopper on the last System Center product for us to tackle, is now fixed.

Hurahh for Microsoft, it's only taken just over two years to fix ;)
