The Virtualized Domain Controller (VDC) cloning feature that is introduced in Windows Server 2012 implements a new event ID 2224 to report on why cloning failed.
For example, an event that resembles the following is logged:

Nevertheless, you must make sure that the new clone computer is authorized to use the gMSA. If authorization is provided through group membership, gMSA works automatically on a clone. This occurs because all group memberships are copied during cloning. However, if the gMSA authorization comes through the direct computer account, you must use the Set-AdServiceAccount Windows PowerShell cmdlet together with the following argument to authorize the clone:

That cmdlet deletes Managed Service Accounts from Active Directory Domain Services and would cause an outage on the source computer. Instead, use the following cmdlet to temporarily uninstall the sMSA from the source computer:
