Hyper-V Export Fails with Error, "failed to add device 'Virtual Hard Disk'" (4038318)

Hyper-V Export Fails with Error, "failed to add device 'Virtual Hard Disk'"

Virtual standbys to Hyper-V begin to fail with the error message below. This normally happens after the initial full export is without problems and a few incrementals afterwards. But over a short period of time, normally within the 24hrs, the export begins to fail.

Replay.Common.Contracts.Virtualization.HyperVException: The operation with VHD virtual disk failed ---> WCFClientBase.ClientServerErrorException: Call to service method http://HyperVHost:8010/apprecovery/api/hypervagent/hypervagent/1cf7c1b8-f834-4ad0-a7a1-c92e883bd3ee/disks/D%253a~|~CRL~|~AgentName~|~disk0.vhdx/Ide PUT failed: The remote HyperV operation has failed ---> Replay.Common.Contracts.Virtualization.RemoteHyperVException: The remote HyperV operation has failed ---> System.AggregateException: One or more errors occurred. ---> System.InvalidOperationException: Error message: 'AgentName' failed to add device 'Virtual Hard Disk'. (Virtual machine ID 926E5EDE-C1F4-438D-B5CD-3439D0E81E2F)

There are 2 possible causes to this issue:

1. The special identity NT Virtual Machine\Virtual Machines lacks the Log on as a Service right on the Hyper-V host machine.

2. D-27066 (5.4.3.106) - Hyper-V Export is failing with "No available IDE controllers have been found"
