CPU and Memory

Using CPU&Memory settings, you can:

Enable nested virtualization support

Parallels Desktop 10 allows you to run Hyper-V virtual machines inside Windows 8 and Windows Server 2012 virtual machines, and to run Xen and kernel-based virtual machines in versions of Linux that support Xen and KVM

Note: Running a virtual machine within a virtual machine may slightly slow down the hosting virtual machine performance.

To enable nested virtualization support, select Enable nested virtualization.

If you want to create or test applications for Windows Phone, first configure Windows to run Windows Phone emulator.

Warning: Do not use Hyper-V virtual machines in a production environment. Microsoft® doesn't support nesting Hyper-V, and so such virtual machines may be unstable.

Enable PMU virtualization support

If you're using virtual machines for software development, you can use a performance monitoring tool, such as Intel VTune Amplifier or OProfile, to optimize the code.

To get started using a performance monitoring tool:

  1. Enable PMU (Performance Monitoring Unit) virtualization support by selecting Enable PMU virtualization.
  2. Start your virtual machine.
  3. Either start using a built-in profiling utility or download and install any performance monitoring tool you like.

Notes:

1. PMU virtualization support can be enabled in Windows (starting from Windows XP) and Linux virtual machines.

2. Enabling PMU virtualization support may slightly slow down your virtual machine performance.
