vmwMemAvail

Amount of memory available to run Virutal Machines and to allocate for
hypervisor needs. It is computed by subtracting vmwMemCOS from
vmwMemSize. The result is the amount of memory available to VMs and to
the hypervisor.
          
To get a more accurate view of memory available to VMs the following property
represents the amount of resources available for the root resource pool for running 
virtual machines.
