Thanks Nawir, I got the solution from Cisco TAC.

Below are the detailed steps

Login to admin VDC and enable telnet feature
****************************************************
Switch(config)# feature telnet
****************************************************

The login via telnet to admin vdc and perform below steps
****************************************************
Switch(config)# no feature ssh
XML interface to system may become unavailable since ssh is disabled
Switch(config)# no ssh key
Switch(config)# ssh key rsa 2048 force
generating rsa key(2048 bits).....
.
generated rsa key
Switch(config)# feature ssh
Switch(config)#
****************************************************

Login via SSH again and disable telnet feature if not required
****************************************************
Switch(config)# no feature telnet
****************************************************
