Steps to Reproduce:
1.Export a vm with direct lun disk
2.Exported vm has no disk
the exported vm is not usable.
The vm should have a copy of the disk

Using LUNs directly as virtual machine hard disk images removes a layer of abstraction between the virtual machines and their data.
Here are the limitations by design:
- Live storage migration of direct LUN hard disk images is not supported.
- Direct LUN disks are not included in virtual machine exports.
- Direct LUN disks are not included in virtual machine snapshots

It could be (hence the RFE)

I see no reason not to add this option when exporting. It would mean of course that the disk would stop being a direct lun, but the request is valid.

technically it could be possible, although it would add a dependency on a storage domain disk in addition to the lun.
alternatively, once we introduce Cinder support then we'd be able to add 'managed' luns for which snapshots are supported by definition.
