Failover Clustering, setting up AD and adding servers to Hyper V manager

First post over here. I have been playing with Server 2012R2, creating VMs etc. I thought of getting adventurous and tried to create a fail over cluster.

1. Do I really need VMM to be able to manage two Hyper V servers from one machine

What I have done so far:

- First step, I had to be domain controller so I installed Active Directory Administrative services on two of my servers and set up a domain

-Before I did this, i was able to go to Hyper V manager and add both servers to Hyper V manager and manage them. Once I created a domain, I am getting permission errors.

Before I installed AD, everything seemed easy. Now I hit permissions errors/ Privilege errors and admin rights at every step.

I tried creating a cluster with just one server and that failed during the cluster create state. The Validation error is below. This doesnt make sense to me as this server is also the domain controller

Description: Validate that all the nodes have the same domain, domain role, and organizational unit.
Validating that all nodes have the same domain, domain role, and organizational unit.

Fqdn	Domain	Domain Role	Site Name	Organizational Unit
NASE-2012-236.yyy.xxxx.com	yyy.xxxx.com	Primary Domain Controller	Default-First-Site-Name	OU=Domain Controllers

Node(s) NASE-2012-236.yyy.xxxx.com cannot reach a writable domain controller. Please check connectivity of these nodes to the domain controllers.
The user can create computer objects in the 'lab.nase.com' domain in the 'OU=Domain Controllers,DC=lab,DC=nase,DC=com' organizational unit.
To successfully create a cluster, either the installer must have the privileges needed to create computer objects in the container of the cluster node computer objects, or a computer object must be pre-created by a domain administrator.
The user creating the cluster requires the 'Create Computer Object' permission on the container where computer objects are created in the domain. If the default container has been modified, then this privilege will need to be granted to the user for the new container.
If a pre-existing computer object is used, please ensure that the computer object is in a Disabled state and that the user creating the cluster has 'Full Control' permission to that computer object using the Active Directory Users and Computers tool prior to creating the cluster.
