虚拟化 – Windows域控制器可以虚拟化吗？

>确保时间保持同步！这是非常重要的.时间不正确的DC可能会造成严重破坏.
>禁用并且不使用快照.恢复到具有许多DC的域中的旧快照将导致大量混乱.
>不要暂停/暂停域控制器.
>确保您的VM服务器不会过载.
>如果您拥有更大的网络,我建议您在真实硬件上运行域中至少一个DC.

Could you explain the snapshot chaos
point? Isn’t reverting to a snapshot
going to act like restoring from
backup,i.e. it will sync recent
changes from the other DCs?

活动目录不支持该目录.复制更新后,将不会重新复制.通常,如果要还原活动目录,则需要执行特殊过程. (http://technet.microsoft.com/en-us/library/cc779573.aspx). KB article Sam Cogan和gharper特别提到了这一点.

In particular,Active Directory does
not support any method that restores a
snapshot of the operating system or
the volume the operating system
resides on. This kind of method causes
an update sequence number (USN)
rollback. When a USN rollback occurs,
the replication partners of the
incorrectly restored domain controller
may have inconsistent objects in their
Active Directory databases. In this
situation,you cannot make these
objects consistent.

We also do not support using “undo”
and “differencing” features in Virtual
PC on operating system images for
domain controllers that run in virtual
hosting environments.
