i've never tested this, but manual means that DRS will give recommendations and you will need to manually apply these. Not sure why anyone would want to do this in the first place? http://frankdenneman.nl/2012/07/27/considerations-when-modifying-the-individual-vm-automation-level/

I just tested this to see what would happen.  I was excepting the power on operations to fail, but they didn't.  The VMs did power on just fine.  It seems that vCD handles answering the confirmations for the host DRS recommends the VM to be powered on.  Normally, the administrator would need to apply the recommendation, but it seems when vCD is in place, this is handled for you, and the VMs get powered on.  I learned something new.  This was tested using vCD 8.10.0.

That said, I would never recommend this since DRS will never move a VM due to a host in the cluster being overloaded.  If vCD is used, fully automated mode is the best recommendation.
