It is attached in the comments

L3 SW in gns3 is nightmare' I apply same config to NSK in gns3 and I can ping from host to SVI in NSK-2

Note:- vlan 30 in NSK-2 have no access port and not allow in trunk so I use 

No autostate

What is NSK ? There must be something wrong with VPCS cuz I cant ping anything on SwitchB whereas in production environment it works fine.

NSK is nexus

And you are correct gns3 l3sw have some issue in inter-vlan 

Your config is correct.
