Leopard server virtual machines are now possible in the Parallels Server Open beta launch.
The Parallels Server Beta program, invites you to toss your proverbial hat into the ring and help them get the product ready for shipping. Parallels Server seems packed with lots of great stuff, like:
The ability to run more than 50 different x86 and x64 guest operating systems on any, Windows, Linux and Mac OS X Server. That’s right, this isn’t just a Mac product; its ready to go on just about any server, PC or Mac.
The option to run virtual machines either in lightweight hypervisor mode (similar in implementation to Desktop for Mac) or in the headless mode via a “bare metal” hypervisor. This second option is particularly interesting as it enables VMs to run in parallel (pun intended) without being dependent on a primary operating system
The ability to – for the first time EVER – run Mac OS X Leopard Server in a virtual machine! Yes, you heard right; if you’re a Mac user, you will be able to run Leopard Server in its own VM. Great for testing and development, but also important for Mac Server admins who want to maximize their Xserve hardware.
