Virtual network interface known limitations

The following known limitations apply to this virtual network interface release:

• With infrastructure NAT enabled for a virtual network interface, no more than one floating IP can target the virtual network interface.
• When a floating IP is attached to a virtual network interface, network address translation (NAT) is performed between the floating IP’s public address and the virtual network interface’s primary IP address.
• Creating an instance group from an instance template that has a virtual network interface with allow_ip_spoofing set to true is not yet supported.
• Not all virtual network interface targets support all virtual network interface policies. The following list shows the current incompatibilities.
  • Virtual server instances do not support disabling infrastructure NAT.
  • The allow_ip_spoofing property cannot be true when the target is a file share mount target.
  • The enable_infrastructure_nat property cannot be false when the target is an instance network attachment or a file share mount target.
  • Secondary IP addresses are not allowed when the target is a file share mount target.
  • A floating IP cannot target a virtual network interface that is attached to a file share mount target.
  • A flow log collector cannot target a virtual network interface that is attached to a bare metal server network attachment or a file share mount target.
  • Select customers have access to virtual server instances with vNICs that are SR-IOV enabled. Flow log collectors cannot target instance network attachments (nor child network interfaces) that are SR-IOV enabled.
