Domain controller roles in a virtual hosting environment

from Microsoft

Tips for DC's migration to a virtual hosting environment and p2v migrations:

1. Disable the write cache on all volumes of the guest operating system that host the Active Directory database, the logs, and the checkpoint file ( It include Active Directory, the File Replication service, WINS, and DHCP).

2. Back up the system state of at least one domain controller in every domain several times a day (Microsoft's recommendation).

3. Do not pause the domain controller for long periods of time before you resume the operating system image. If you do pause the domain controller for a long time, replication may stop and cause lingering objects.
Event ID: 2042

4. Active Directory does not support other methods to roll back the contents of Active Directory except of a system state restore.

5. Microsoft strongly recommends that:

you locate critical server roles on domain controllers that are installed directly on physical hardware. Critical server roles include the following:

Global catalog servers
Domain Name System (DNS) servers
Operations master roles, also known as flexible single master operations (FSMO)

It means that you should not use your VMs with FSMO roles. But if you have hardware failure on a physical server, you are ....
