Parallels Desktop provides nested virtualization support (VT-X technology) that allows you to run Hyper-V virtual machines inside Windows 8, 10, and Windows Server 2012 virtual machines, and it is not supported the macOS virtual machine. Nested virtualization allows the emulators execution. Ex: Docker, Android emulator and IOS emulator (Xcode). This feature will allow the isolation of the development environment. The libraries, frameworks and configurations will be contained within the VM. Easy recovery and easy sharing.
