1. Coming from Virtual PC 7, Parallels import went smooth, vmware converter resulted in a virtual machine where the mouse and keyboard input was not responsive, Import of the Parallels VM into Fusion went smoothly too (Importer beta 2 may do the same with the VPC7 image, i should give it a try). No freezes or crashes with both.
  2. With Parallels Desktop for Mac you can use Windows that you set up using VMware Fusion, Microsoft Virtual PC, and Virtualbox.

You can import existing third-party virtual machines and run them in Fusion.

  1. Select File > Import.
  2. Browse to the existing virtual machine you want to import and click Open.
  3. Type the name for the imported virtual machine in the Save As text box and indicate where to save it.
    The default destination is the Virtual Machines folder created by Fusion.
    Fusion displays the disk space needed for the import, and the space available on the current disk.
  4. Click Import.
    When the import is complete, the virtual machine appears in the virtual machine list, in the powered-off state.
  5. Click Finish.
    Fusion installs VMware Tools after the virtual machine powers on, and reboots the system after the Tools installation is complete.

You have a separate Fusion version of the third-party virtual machine.
