VMM Naming Convention
This is HILARIOUS! 
I’ve got error when installing SCVMM 2012 RC, terribly sorry I didn’t print screen the error, but the same error explanation just like this link :

The above link is happening with SCVMM 2008 R2 SP1

and once again, the above link is happening with SCVMM 2012 Beta, now is happening to me, arrghh 
Renaming the hostname is pretty easy, but because this is my lab environment and I put all the roles & services together including AD CS roles!
