SCVMM 2012R2 要点转载摘译
Creating the distributed key management container in Active DirectorySome of the data stored by VMM needs to be held securely, so it cannot be compromised.
For example, when you store user credentials in VMM for Run As accounts, the passwords for
these are encrypted. When you install VMM, you are given the choice of where to store the
encryption keys, as shown in the following screenshot:
It is required to always store your encryption keys in Active Directory if you are going to deploy
a highly available (clustered) installation of VMM.
The account used to install VMM must have full control over the container in Active Directory
for the duration of the installation. During the installation, the installer program reconfigures
the security of the container to ensure that only the correct security principles have access.
For a small scale installation, a single container in the root of Active Directory could
be created to store the encryption keys. For a large-scale implementation where several
different installations of VMM may be required due to the number of hosts and/or virtual
machines, it is advisable to create a parent container in Active Directory and then have
containers within the parent for each installation of VMM.
Installing Virtual Machine Manager
Getting ready
You will need to have sufficient access to Active Directory to create Container objects.
How to do it…
The following diagram shows you the high-level steps involved in this recipe and the tasks
required to complete this recipe:
Overview of Recipe:
Actions:
Creation of new container in Active Directory for
Distributed Key Management in VMM using
PowerShell
Applying the required security permissions to the
newly created Active Directory container using
PowerShell
Prerequisites (not covered by this recipe):
Obtaining an account with sufficient privileges for
creating a container in Active Directory
Obtaining an account with sufficient privileges for
changing ACLs on the new container in Active
Directory
There are two possible methods of creating a container in Active Directory: one is using ADSI
Edit and the other is via PowerShell. The method discussed here will be PowerShell-based:
1. On a Domain Controller, or a machine where the Active Directory PowerShell Module
is installed, open an elevated PowerShell console.
2. The following PowerShell line will create a container called DKMVMM in the root of
Active Directory:
New-ADObject –Name DKMVMM –Type container –Path
"DC=ad,DC=demo,DC=com"
3. Once the container has been created, the user who will be installing VMM needs to
have full control of the container and that permission must apply to the container and
all descendant objects. The following PowerShell will perform this function:
Set-PSDrive AD:
$VMMInstallAccount = Get-ADUser -Identity Install_VMM
$SID = New-Object
System.Security.Principal.SecurityIdentifier
$VMMInstallAccount.SID
$DKMVMMacl = Get-Acl -Path "CN=DKMVMM,DC=ad,DC=demo,DC=com"
$ObjectGuid = New-Object Guid 00000000-0000-0000-0000-
000000000000
$newACL = New-Object
System.DirectoryServices.ActiveDirectoryAcce***ule
$SID,"GenericAll","Allow",$objectguid,"All"
$DKMVMMacl.AddAcce***ule($newACL)
Set-Acl -AclObject $DKMVMMacl -Path
"CN=DKMVMM,DC=ad,DC=demo,DC=com"
This recipe is complete and the Distributed Key Management container is now ready to be
used by DEMO\Install_VMM during installation.
