100%

Steps to Reproduce:
If you need a lun for the manager storage before it exists, not possible to apply hook before install the manager.

Actual results:

Expected results:

Because is not possible to use vdsm hook before install the manager, could be possible to define an fcoe network via vdsm API.
Vdsm after that restore networking configuration using persistence mechanism and it should work for new hosts as well.
