Run services on Snow Leopard Server

Hi everyone.. i have the last version of Parallels on my mac with Snow leopard server 10.6.2 up to date who is running perfect and the installation was clear.. i tried to run a service called software update but it didn't work..

I configured recently a mac mini with the same version of OS and running software update service without problem.. (native.. i mean i didn't use VM Fusion in this case)

So.. anyone know if Parallels can run services on Snow Leopard server? is it supported?

Thank you..
