Vinternals wrote a short article on how to de-install or hide the Capacity Planner plugin for VirtualCenter:
Capacity planner is rather pesky to have hanging around on every VirtualCenter box in the enterprise… especially if you use some other tool for the job! So just add this line to the end of your VirtualCenter install script:
msiexec /qn /x {2A2750C9-E14E-4635-8595-C1CD214445B0}
and away she goes!
Altenatively, you can simply hide it from the Virtual Infrastructure client by adding the following in the
section of vpxd.cfg <vcp2v>
<dontstartconsolidation>true</dontstartconsolidation>
</vcp2v>
