Detaching a NIC from a VM

You can detach a network interface card (NIC) from a virtual machine (VM) it is attached to, at any time. Network traffic directed to this NIC stops being directed to the VM once the NIC is detached.

This action updates the state of the NIC from in-use to available. For more information, see About NICs > NICs Attachment to Instances.

You cannot, however, detach the primary network interface from a VM.
