+Multi node with MacVTap compute node |
|
| 611 |
+~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~ |
|
| 612 |
+This scenario applies, if you require OpenStack provided l3, dhcp or metadata |
|
| 613 |
+services. Those are hosted on a separate controller and network node, running |
|
| 614 |
+some other l2 agent technology (in this example Open vSwitch). This node needs |
|
| 615 |
+to be configured for VLAN tenant networks. |
|
| 616 |
+ |
|
| 617 |
+For OVS, a similar configuration like described in the |
|
| 618 |
+:ref:`OVS Provider Network <ovs-provider-network-controller>` section can be |
|
| 619 |
+used. Just add the the following line to this local.conf, which also loads |
|
| 620 |
+the MacVTap mechanism driver: |
|
| 621 |
+ |

|
| 627 |
+ ... |
|
| 628 |
+ |
|
| 629 |
+For the MacVTap compute node, use this local.conf: |
|
| 630 |
+ |
|
| 631 |
+:: |
|
