:Keyword Arguments:
* *vnic_type* (``string``) --
used when launching instances with pre-configured ports.
Examples:
normal: a traditional virtual port that is either attached
to a linux bridge or an openvswitch bridge on a
compute node.
direct: an SR-IOV port that is directly attached to a VM
macvtap: an SR-IOV port that is attached to a VM via a macvtap
device.
direct-physical: an SR-IOV port that is directly attached to a
VM using physical instead of virtual
functions.
baremetal: a baremetal port directly attached to a baremetal
node.
virtio-forwarder: an SR-IOV port that is indirectly attached
to a VM using a low-latency vhost-user
forwarding process.
Defaults to ``CONF.network.port_vnic_type``.
* *port_profile* (``dict``) --
This attribute is a dictionary that can be used (with admin
credentials) to supply information influencing the binding of
the port.
example: port_profile = "capabilities:[switchdev]"
Defaults to ``CONF.network.port_profile``.
* *create_port_body* (``dict``) --
This attribute is a dictionary of additional arguments to be
passed to create_port method.
