Question

What is the recommended value for uvmm/overcommit/reserved?

Answer

A good starting point would be 2GB of reserved memory for the host operating system. For additional buffers you might use a value of 3GB.
This value has to be set only on the UCS server hosting UVMM and will be set on all virtualization hosts.

To use 3GB configure the value as follows:

ucr uvmm/overcommit/reserved=3221225472
