  • Parallels Desktop 10 for Mac Home Edition
  • Parallels Desktop 9 for Mac Standard Edition

Cannot install OS X virtual machine:


     "The Virtual Machine cannot be started. Mac OS X virtual machines can run only on computers having Mac OS X Leopard or Mac OS X Tiger installed. Problem ID 397."

The error is the same regardless of whether you try to install OS X from the host Mac's Recovery Partition, or by using a .dmg file extracted from the 'Install Mac OS X Lion' installer.

Also, cannot start up an OS X guest VM that was created on a different MacBook Pro 15in and copied to the 13in.
