DNS resolution across VPCs connected via S2S VPN

##### CLOUDSTACK VERSION

##### CONFIGURATION

##### OS / ENVIRONMENT

##### SUMMARY

Current VR only resolve its own Guest Network DNS zone record and external records. When two or more peered VPC network, user has to manage the host resolution either by host file or create another forwarder point to VR in upstream DNS. I would say it would be more useful if we populate all DNS record across each peered zone VR with proper domain suffix. So the user do not need to discover new IP changes from peered zone.

Comece examinando o componente CloudStack VR e como as zonas DNS de VPCs emparelhadas são representadas na versão 4.20. Esclareça os sufixos de domínio esperados, o comportamento de propagação dos registros e o uso voltado ao usuário antes de identificar a implementação e os testes relevantes; considera-se concluído quando a resolução DNS funciona entre VPCs emparelhadas sem gerenciar arquivos de hosts ou encaminhadores upstream.
