Hi,

I confirmed VPC in two Nexus switches and PVC peer-Link is down.

Is there any issue with the configuration.

you need to make peer-keepalive vrf aware 
peer-keepalive destination 192.168.1.2 source 192.168.1.1 vrf  management

Hi,

Are physcical ports e1/1 and e1/2 up? If they are down, you may want to add the proper speed command to all and see if the ports come up.

speed xxx

Also, the vpc peer-link PO should have

spanning-tree port type network
