Title: Virtual Domain Controllers
The supported status of Windows on VMWARE, in a nutshell, is this
 
Premier Customer
    You have best effort support and if they can't figure it out, you have to duplicate the issue on hardware.

I, myself, would have no issue running Windows on ESX, I have seen some amazing things on it. As for GSX, I would probably run VS instead so there is no doubt about the supportability.
 
That being said, I know of companies (like HP for instance) that have offical support for Windows on VMWARE and have a very good track record of working out the issues. In fact, last time I asked, they hadn't hit a problem they weren't able to get corrected prior to going to the point of duplicating on physical hardware and getting MS involoved. However, if worse comes to worse, they will move the image to a physical and do that interface with MS. That is just my outside look into what I heard about that group doing that though so if you went that direction, obviously sit down and discuss it at length with the salesman and techs involved with that stuff.
 
Personally, until MS has a ESX version they need to be supporting Windows on ESX (they have a GSX look alike so I can understand them not being forced into supporting it). They have so many people doing it against their wishes anyway that they are starting to look a bit silly for it. It is a bad precedence, in my mind, to say something isn't supported that most people are willing to just go do anyway. It puts people that much closer to doing other things MS doesn't support because hey, doing this other thing that they said wasn't supported worked so well we made it the whole corporate direction. I visualize people running all sorts of software that hack into LSASS and intercept LDAP calls and anything else. There are no levels of what is and isn't supported by MS. It is supported or not depending on how big of a check you send MS every year. That is black and white. Again if you get used to doing things MS says are unsupported, you will probably be quicker to do it more and more. MS Support suffers in that case in my opinion.

Thanks, Al.
 
Given all the rants, er, discussions, about single purpose servers (thanks, Joe), I'd like to not do that.  The sites (~18 of them) range in size from 20 to 200 users.  Consistency is good, so whatever solution we come up with I plan to do the same thing in each remote office.
 
This change to VM is more about hardware reduction in outlying offices rather than specific cost savings measures (though of course, those are always appreciated up the chain).  If there are reasons to not go with VMs on DCs (e.g. if memory usage in the VM environment can cause AD corruption), I need to know that.  Hearing that the configuration is not 'officially' supported is not a show stopper if many people are successfully doing it and feel it should be supported by MS.

Could you just do the file/print on the DC?  In a small environment you could probably get away with it.

Hi All,

I have a question about running DCs on GSX server.  I understand that MS does not support this configuration, but I've heard that many people are running DCs in this fashion.  Can anyone give some advice in this arena?  The idea here is to do VM for a file/print, and another one for a DC in our remote sites.  Currently, we've got different hardware for each box, but we're trying to consolidate a bit out there.

Thank you.
