Ubuntu desce diariamente à noite - VM

Question

Temos uma VM Ubuntu no Hyper-V e nela temos um servidor LAMP instalado e um domínio interno acessível a partir da intranet.

Todos os dias, temos que reiniciá-lo porque a conectividade com o servidor fica inativa.

Quando logamos na VM, a rede está inoperante, sem internet

Eu vi os logs e algo aconteceu às 2h

Aqui tem mais informações:

Answer 1

Eu não posso comentar, então vou responder aqui.

A linha udev: renamed network interface eth0 to eth2 não é o problema no seu log? veja link ou link para alguns exemplos de resolução.
