Pretty much all newer versions of UC applications have started supporting virtualization so they can be installed on the VMware. 

Have a look at dockwiki for virtualization supported apps:

Some applications like CUCM version 4 were windows based previously but going ahead with version 5, 6 onwards the OS has been changed to Linux Operating system.

Let me know if you need any more information.
