Não sou muito especialista em openstack. Tenho dois problemas no meu ambiente openstack com dois controladores.
- Quando verifico o estado, mais hosts estão inativos (mas eles estão ativos e em execução, e a VM está em execução neles):
$ openstack compute service list --service nova-compute

isso porque não consigo implantar uma nova VM porque recebo o erro:
Error: Failed to perform requested operation on instance " test.ts1.mydomain.com", the instance has an error status: Please try again later [Error: No valid host was found. There are not enough hosts available.].
- Posso gerenciar a VM pela GUI, se eu tentar reconstruir um servidor, ele ainda estará pendente
Do controlador vejo estes erros:

Tentei reiniciar rabbitmq-server.servicee reinicializar os controles, mas não consegui resolver o problema.
Funcionou até alguns dias atrás. Alguém tem ideia de como consertar isso?
Resolvi reiniciar esses serviços abaixo (no controlador e no computador):
