Openstack-Instanzen haben keinen Zugang zum Internet

Ich habe Landscape Installer mit MAAS verwendet. Wenn ich mit SSH in den Neutron-Knoten einsteige, kann ich eine Verbindung zum Internet herstellen, Instanzen jedoch nicht.

Die IP-Route auf dem Neutron-Knoten zeigt, dass das Standard-Gateway über meinen MAAS-Controller-Knoten erfolgt:

Es wurde festgestellt, dass dies eine falsche Gateway- und CIDR-Konfiguration im OVS-Konfigurationsschritt der Installation ist.

Das Netzwerk wurde auf 172.26.0.0/24 gesetzt, wenn es 172.26.1.0/22 ​​hätte sein sollen, und kollidierte daher mit dem vorhandenen Netzwerk.

Erhielt Administratoranmeldeinformationen und führte eine Subnetzaktualisierung durch. Außerdem wurde festgestellt, dass das Gateway für das externe Netzwerk-Subnetz nicht festgelegt wurde. Sobald dies festgelegt wurde, erhielten die Instanzen eine Netzwerkkonnektivität.
