Managing Virtual Machines 92
Memory Preferences
On this tab maximum amount of physical memory (RAM) that system should reserve to all
simultaneously running virtual machines on your computer can be adjusted. This setting applies
to all users of your computer.
The maximum memory allowed depends on physical RAM size of your computer. Some
memory must be reserved for your primary operating system. From the remainder you can
select the maximum RAM allowed for Parallels Workstation. If you have one instance of virtual
machine running, it may use all the memory allocated here. In case of several simultaneously
running virtual machines this memory will be shared between them. Memory for a specific
virtual machine is set on the
Memory tab (page 112) in Configuration Editor.
Memory amount should be multiple of 4. If it doesn't then you will receive error notification
when trying to save memory options. To set an appropriate memory amount you may use the
slider, the spin buttons in the
Reserved memory limit field, or type a value directly into the field.
