I am Installing a new Hyper-V 2012 server into a data center site, this will host a domain controller and some kind of backup server to store snapshots of VM's. This will be a standalone server or to be clearer this wont be in a cluster, it will however be able to contact other domain controllers in others sites over fast branch office VPN's and a 1GBIt site to site link. no other physical domain controllers will be on site.
I have another hyper-V server in a different data center running 2008 R2, I specifically remember when setting this up that I should not join the hyper-V host to the domain due to installing a domain controller as a virtual guest, as in an emergency situation and my DC's all were off and uncontactable to each other, I wouldn't be able to log into the 2008 hyper-V host if the domain controller hosted within it did not come online. (unless I am mistaken and this only effected clusters)
So my question is, is this still the same in server 2012 (standard)?
I have read that there is a new feature for windows 2012 hyper-V clusters that protects you from this, but I assume this is just for clusters and not for standalone systems. To add a bit of extra detail the domain is 2008R2 function level.
Thanks
