No still not yet resolved 

[MHM Cisco World]

There both or one of port members have any nameif?

Nameif must use only under redundant interfaces not under port members 

Also check if nameif inside use by other interface

Yes I have checked Inside nameif i didn't use any other port and gig0/0,gig0/1no nameif mentioned and this ASAv i have imported GNS3 and Oracle virtual box lab setup

from cisco doc.

• Redundant interfaces are only supported on the ASA 5500-X platform; they are not supported on the Firepower 4100/9300, ASASM, and ASAv.

sorry this feature not support in asav
