  • System Center 2012 R2 Virtual Machine Manager cannot deploy a new or imported VMWare template.
  • A virtual machine with that uses VHDX cannot be refreshed correctly in System Center 2012 R2 Virtual Machine Manager, and you receive the following error message:

Refresh job failed with error 2912: The requested operation cannot be performed on the virtual disk as it is currently used in shared mode (0xC05CFF0A)

  • Database operations sometimes fail with "FailedToAcquireLockException."
  • A new virtual machine template from a template that specifies an operating system profile doesn't use credentials from the operating system profile.
  • Virtual machines in VMWare that connect by the using Cisco N1000V dvSwitch are unavailable for management from Virtual Machine Manager.
  • System Center Virtual Machine Manager service crashes if you disable one of the teamed network adapters.
  • The Get-Scstoragearray -host command should return storage arrays that are visible to a host that is using zoning.
  • During the discovery of a network-attached storage (NAS) provider, the credentials that are used do not include a domain name.
  • Some localized strings are not displayed correctly in the UI.
  • A query to find the certificate should match both the subject name and the friendly name because FindBySubjectName is a wildcard search.
  • Template deployment fails, and you receive the following error message:

Error (2904)

VMM could not find the specified path on the <Server name> server.

The system cannot find the path specified (0x80070003)

  • Virtual Hard Disk (VHD) cannot be mounted on a host because VHD conflicts with other disks because of a stale entry that was left in the dictionary of Virtual Machine Manager memory.
  • Differencing disk based deployment may fail because the parent disk is being refreshed as noncached.
