Chapter 7. Creating an instance with a VDPA interface
You can create an instance with a VDPA interface by requesting a port for your instance that has a vNIC type of VDPA.
Limitations
- You cannot suspend or live migrate an instance that has a VDPA interface.
- You cannot detach the VDPA interface from an instance and then reattach it to the instance.
Procedure
Create a network that is mapped to the physical network:
$ openstack network create vdpa_network \ --provider-physical-network tenant \ --provider-network-type vlan \ --provider-segment 1337
Create a subnet for the network:
$ openstack subnet create vdpa_subnet \ --network vdpa_net1 \ --subnet-range 192.0.2.0/24 \ --dhcp
Create a port from a VDPA-enabled NIC:
$ openstack port create vdpa_direct_port \ --network vdpa_network \ --vnic-type vdpa \
Create an instance, specifying the NIC port to use:
$ openstack server create vdpa_instance \ --flavor cirros256 --image cirros-0.3.5-x86_64-disk \ --nic port-id=vdpa_direct_port --wait
An "ACTIVE" status in the output indicates that you have successfully created the instance on a host that can provide the requested VDPA interface.
