STATUS_VIRTUAL_DISK_LIMITATION

The virtual disk backing file has an unsupported attribute

This status belongs to the lower storage, disk, virtual-disk, or file-system repair path. For STATUS_VIRTUAL_DISK_LIMITATION, treat it as a boundary between the caller and the storage stack, not as a generic application error.

The default message for this NTSTATUS says virtual hard disk files must be uncompressed, unencrypted, and not sparse. The failure is therefore about properties of the VHD/VHDX backing file or file system, not merely about free space.

For STATUS_VIRTUAL_DISK_LIMITATION, the most useful evidence is the failing operation, device or volume identity, storage-event log, disk health data, and whether the volume was online, read-only, virtualized, encrypted, compressed, sparse, or under repair.

What to inspect

  • Check compression, EFS encryption, sparse attribute, and ReFS integrity settings on the VHD or VHDX file.
  • Move or convert the virtual disk to compliant storage.
  • Record the host file path as well as the guest disk identifier.
