Hello,
My apologies but I'm a little confused with the question.
Your vCentre 5 server would sit on a Windows Based VM, so really shouldn't it be what operating systems are supported with your currently version of VMware Workstation. vCentre 5.0 runs on only the 2003/2008 OS. VMware Workstation 10 supports all Windows Operating Systems.
