Chapter 7. Creating an instance with a VDPA interface
This feature is available in this release as a Technology Preview, and therefore is not fully supported by Red Hat. It should only be used for testing, and should not be deployed in a production environment. For more information about Technology Preview features, see Scope of Coverage Details.
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, live migrate, shelve, or evacuate 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
$ openstack network create vdpa_network \ --provider-physical-network tenant \ --provider-network-type vlan \ --provider-segment 1337Copy to Clipboard Copied! Toggle word wrap Toggle overflow Create a subnet for the network:
openstack subnet create vdpa_subnet \ --network vdpa_net1 \ --subnet-range 192.0.2.0/24 \ --dhcp
$ openstack subnet create vdpa_subnet \ --network vdpa_net1 \ --subnet-range 192.0.2.0/24 \ --dhcpCopy to Clipboard Copied! Toggle word wrap Toggle overflow Create a port from a VDPA-enabled NIC:
openstack port create vdpa_direct_port \ --network vdpa_network \ --vnic-type vdpa \
$ openstack port create vdpa_direct_port \ --network vdpa_network \ --vnic-type vdpa \Copy to Clipboard Copied! Toggle word wrap Toggle overflow 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
$ openstack server create vdpa_instance \ --flavor cirros256 --image cirros-0.3.5-x86_64-disk \ --nic port-id=vdpa_direct_port --waitCopy to Clipboard Copied! Toggle word wrap Toggle overflow An "ACTIVE" status in the output indicates that you have successfully created the instance on a host that can provide the requested VDPA interface.
