Add multiple network Adapters to a VM.

[NikhilPathak]

I am looking for a command to add new Network card to the VM.

See New-NetworkAdapter.

You'll have to repeat the cmdlet for multiple vNICs.

Hi LUcD,

We did try that, but received the error as

New-NetworkAdapter -VM $vm_details.Name -NetworkName "custom_nw_10.78.215.XX" -Type e1000 -StartConnected -WakeOnLan

New-NetworkAdapter : 6/26/2019 10:59:37 AM New-NetworkAdapter The network "custom_nw_10.78.215.XX" doesn't exist on the host.

It looks as if that portgroup doesn't exist in your environment.

Is that name included in the list when you do a Get-VirtualPortgroup

[NikhilPathak]

No, it doesnt contain. Do i need to add that first?

The purpose here is to add just a nic 1 wih no network connected.

Yes, the NetworkName parameter is a required parameter.
So you have to provide an existing portgroup.

I normally use a 'dummy' portgroup for that, and only set the final portgroup later on.

And you can use the StartConnected parameter to make sure the vNic is not connected.
