Decrease VM evacuation times

Decrease VM evacuation times by increasing the amount of concurrent VMotion migrations per host (unsupported):
-On your vCenter server, edit c:\docs & settings\all users\application data\vmware\vmware virtualcenter\vpdx.cfg
-Insert the following lines between the [vpdx] XML tags:
[ResourceManager]
[maxCostPerHost]24[/maxCostPerHost]
[/ResourceManager]
Cold Migration has a cost of 1. Hot Migration has a cost of 4.
