We define the maximum bound value of memory reclaimed from the particular virtual machine machine by ballooning technique. We can define value in MB (Megabytes) by editing the virtual machine advanced configuration parameter.

Right Click the virtual machine and  click Edit Settings
Go to Options Tab > Advanced > General

Click on Advanced Parameters and Click Add Row and add the below name and values.

sched.mem.maxmemctl  = 200  to limit the balloon driver to only reclaim 200 MB of memory from this particular virtual machine as part of ballooning process.

  Please refer my blog post on disable and enable balloon driver
