Eu usei o instalador de paisagem com o MAAS. Quando eu faço SSH no nodo Neutron, posso pingar para a internet, mas as instâncias não podem.

Foi encontrado um gateway e um erro de configuração do CIDR na etapa de configuração do OVS da instalação.
A rede foi definida como 172.26.0.0/24 quando deveria ter sido 172.26.1.0/22 e, portanto, estava colidindo com a rede existente.
Obteve credenciais de administrador e fez uma atualização de sub-rede e também notou que o gateway da sub-rede de rede externa não estava definido. Depois que isso foi definido, as instâncias receberam conectividade de rede.
