The reserved memory setting specifies the maximum amount of host RAM that Workstation Pro is allowed to reserve for all running virtual machines. Reserved memory is not allocated in advance.
To configure the reserved memory setting, select and move the Reserved memory slider to select the reserved memory amount.
If you set the reserved memory value too high, the CPU might thrash if you run other applications on the host. If you set the value too low, virtual machines might perform poorly, and you cannot run as many virtual machines at the same time.
On 64-bit hosts, the maximum amount of memory for each virtual machine is 64GB. On 32-bit hosts, the maximum amount of memory for each virtual machine is 8GB. Workstation Pro prevents powering on virtual machines that are configured to use more than 8GB of memory on 32-bit hosts. Memory management limitations on 32-bit operating systems cause virtual machine memory to overcommit, which severely affects system performance.
The total amount of memory that you can assign to all virtual machines running on a single host system is limited only by the amount of RAM on the host system.
