Encrypt your virtual machine with a password to control the use of the virtual machine and access to its contents. If you have VMware Fusion Professional, you can also turn on restrictions to prevent users from changing most configuration settings. You can also set other virtual machine policies.

You can set a password for a virtual machine that is required to open the virtual machine. You can remove the encryption or change the password at any time.


Large virtual machines, such as those that exceed 50GB, might generate a low disk space warning.

If you have a VMware Fusion Professional license, you can also turn on restrictions, so that users are prevented from modifying the virtual machine. For example, you can enable restrictions to prevent users from removing virtual devices, changing the memory allocation, modifying removable devices, and changing the virtual hardware compatibility.

Other restrictions include setting a policy that forces users to change the encryption password if they move or copy the virtual machine. For example, a teacher might provide a copy of the virtual machine to all students in the class and set this restriction so that all students must create their own encryption password.

You can also optionally set a policy that prevents users from connecting USB devices to the guest operating system.

When you turn on restrictions, you set a restrictions password. After restrictions are turned on, you cannot make changes to the virtual machine configuration settings or restrictions policies unless you first turn restrictions off. To turn off restrictions, you must enter the restrictions password.


The restrictions feature is available only if you have the VMware Fusion Professional license.
