Fusion now allows non-server OSX 10.5 and 6 to be virualized

Lion the on only OS X that explicitly allows virtualization, the only condition is the Host OS be Lion also, and Parallels already supports this.

With Paragon solution on Lion with Parallels, you can have Leopard, Snow Leopard and Lion as VMs.

 

This is only true for Parallels Desktop but not for Parallels Server. Desktop version is not usable in a server environment. So for professional users who is ready to pay 20 x more than for a single desktop user, Lion is not an option he can choose. *sight*

 

You have to wait for the next version of Parallels Server for Mac.

 

So, if we have rights to virtualize Mac OS X 10.4, 10.5 or 10.6 in Europe, it would be nice if Parallels implements this!
