Yea I'm trying to train myself on 2012 as well.
So with a copy of 2008 STD I get 1 virtual copy correct?
So I can build 1 physical server, and then use it for AD, and create a virtual server inside of it for the RDS using the virtual copy? Is this 100% correct? (Ideally I like this method best, but wish I could incorporate it into 2012)
Your correct about them combining user/device cals. and yes rds cals are different than regular user cals.
I'm thinking 2008 STD might be the best way to go about this for costs.
Was hoping 2012 might be cheaper but I don't quite understand the 2012 essentials pricing. Like would I have to buy 2012 Essentials + buy 5 user cals + buy 5 rds cals? That would be a waste of money.
Thanks for your help guys. This is helping me clear the air about some things
on Server 2012 you do get a Virtual License to run on-top of the Host. Server 08 R2 has different Licensing requirements... heres a link to the info for 08:
https://www.google.com/url?sa=t&rct...ZwHx3OHb8A96g&bvm=bv.1355325884,d.b2I&cad=rja It is a download from Microsoft (although the link goes through google?

)
I would still go Server 2012. Its easier to find CAL's, Software, and its the latest and greatest. Haven't heard nothing bad about it either, hell even Metro hasn't been ragged on that bad in 2012. But yes, Server OS+CAL's+RDS CAL's. it is a bit of a rip...
That being said, you cannot put RDS on 2012 Essentials. not supported. Has to be Server Standard to my knowledge.
I have never added additional roles to the bare metal install Hyper-V "host".....only the Hyper-V role. No additional roles.
I have read that:
*It's not supported by Microsoft
*It won't let you
*Mixed myths (or truth) that licensing doesn't allow anything other than hyper-v role
*I have heard that if virtual guests and other domain members need to contact the Hyper-V host for anything AD related...system clocks will have timing issues.
I have also read that some people have installed a DC role to the Hyper-V host. They say without issues. Dunno if issues came up for them over time. IMO...best to install AD related services into virtual guests..and allow the Hyper-V host focus resources on being just a hyper-v host.
From my research/expirenece, although it may not be supported, it does work just fine. On Server 08 R2, trust me you can install Hyper-V, AD, DNS, DHCP, P&F, VPN, FTP, IIS and WSUS (and WAMP, a couple game servers ocaasionally, NOD32 for A/V and cloud+local backups). It dont care at all. At least MY server doesn't. It runs everything and the kitchen sink, and has been for 18 months with very few issues (those were typically my fault!

)
But yes, according to that doc i linked, technically the Host is the Host and nothing else, and everything else should be virtualized with separate licenses...
Ok, My head hurts now... server licensing always does that... Its massively convoluted, doesn't matter what version it is....
