That works because you have effectively disabled ballooning for the VM, 
which is not really solving the underlying problem.

I also recently started getting these errors.  They started when I 
upgraded from 3.4.0 to 3.4.2.
The error appears on certain VMs (but not all) consistently every 15 
minutes.  It doesnt matter if the Memory Balloon Device Enabled 
checkbox checked or unchecked.
I got the message to stop appearing by changing the value of Physical 
Memory Guaranteed to match the VMs configured memory.

Just an FYI.
In my case the balloon driver was installed and it was running. The 
problem was eventually resolved by uninstalling the entire agent 
suite, rebooting and reinstalling it. Doing the same just for the 
balloon driver didn't work.
