Create a Single Segment Virtio VM Network

You can create a single segment Virtio VM network on a default physnet and extend the network to DC Edge.

Note

Note

VLAN provisioning depends on the following:

Neutron Virtio ports are bound to a host during VM launch.
DHCP ports are bound during subnet creation.
DC Edge extension is achieved using explicit port-create.

The following figure shows an overview of a single segment Virtio VM Network with DC Edge.
