Memory Settings

To set the amount of RAM available to the virtual machine, use the Memory pane of the Virtual Machine Configuration dialog.

In the Main memory field, you can set the amount of RAM that will be available to the virtual machine. You can choose any available value, but it is recommended that you set the value provided in the Recommended range field below the slider.

By default, the optimal size is the amount of RAM the guest operating system requires. If some of the applications installed in your virtual machine need more RAM, you can set a greater amount of RAM for this virtual machine, provided the memory resources of the host computer are enough for running both the primary operating system and this virtual machine.

Note: If the host computer has 1 GB of RAM, it is strongly recommended to assign not more than 512 MB to a single virtual machine.

To set the required value for this type of memory, do one of the following:

• drag the slider
• use the spin box arrows
• type the value directly into the Main memory field

When you finish, click OK to save the changes and quit the Virtual Machine Configuration dialog. If you do not want to save the changes, click Cancel .
