Hi Misak,

  I do not think we will be supporting any in the near future. Enabling gfapi means that access mechanism of drive changes and i think we will need to stop the vms.

Hi,

will it be a more clean approach? I can't tolerate full stop of all

environment. Will it be some migration mechanisms in future?

Best regards,
Misak Khachatryan
