OS X Server on VM
Apple has apparently changed its tune on the ability to run Mac OS X Server inside a Virtual Machine (such as VMWare's Fusion or Parallels Desktop). Though the company's license wording previously disallowed running multiple copies of Mac OS X Server on a single Mac, the new software license agreement included with Leopard reads "This License allows you to install and use one copy of the Mac OS X Server software (the "Mac OS X Server Software") on a single Apple-labeled computer. You may also install and use other copies of Mac OS X Server Software on the same Apple-labeled computer, provided that you acquire an individual and valid license from Apple for each of these other copies of Mac OS X Server Software." According to TidBits, the license change could herald new offerings from Parallels and VMWare that allow Mac OS X to run inside a virtual environment on top of itself.
Ben Rudolph, Director of Corporate Communications for Parallels, told the publication, "Enabling Leopard Server to run in a virtual machine may take some time, but we're working closely with Apple on it and will make it public as quickly as possible." Pat Lee, Senior Product Manager at VMware, concurred, saying "We applaud Apple for the exciting licensing changes implemented in Leopard Server. Apple customers can now run Mac OS X Server, Windows, Linux and other x86 operating systems simultaneously on Apple hardware so we are excited about the possibilities this change presents."
The Leopard Server license agreement, however, restricts virtualization to "Apple-labeled hardware."
System administrators say the ability to run multiple instances of Mac OS X Server on single systems would provide great enhancements to productivity and resource utilization.
