Released in a beta, Parallels Server from SWsoft allows multiple copies of Mac OS X Server 10.5 to run on Mac Pro or Xserve computers.
The software also runs on Windows- or Linux-based servers, and can be used either with the Parallels lightweight hypervisor or in "bare metal." With the hypervisor, virtual machines operate with a primary operating system; in "bare metal," virtual machines run independently without being dependent on a host operating system.
Support for 50 Operating Systems
The company said that Parallels Server is the only virtualization product that allows administrators to choose the hypervisor or bare-metal option during installation. Parallels Server supports more than 50 different guest operating systems, including Windows Server, Red Hat Linux, SUSE Enterprise Linux, Sun Solaris, and Mac OS X Server.
