why does your Linux VM need two network interfaces ?

also a nic in the host is down.

The default Virtual Machine Network is usually called VM Network, I assume you have changed this.

Also if both those uplinks are connected to a vSwitch, it is likely they will load balance between them, so traffic will go out vmnic0, and then vmnic1 - but vmnic1 is down and not connected.

WHY, have you create a new vSwitch, New Portgroup and with another uplink ?

Yes as I still not connected the cable to the vmnic1 yet I want to make sure the network setting is correct , if it is correct suppose one of the nic will show down inside Linux but now it shows both connected

if there is no traffic flowing through vmnic1, and your Linux VM is connected to New Portgroup, and vSwitch1, which is connected to vmnic1, then it will not get an IP Address.

remove nics and add them again - no need for Passthrough, this is using a physical nic.

You can just use virtual nics.

delete the network interfaces in the VM, and re-add as default.

those MAC ADDRESS are different!
