Placa de rede ubuntu server 18.04 [RESOLVIDO]

"As primeiras quatro placas de rede virtual podem ser configuradas em detalhes na janela do Gerenciador VirtualBox. Placas de rede adicionais podem ser configuradas usando o comando VBoxManage."

"O VirtualBox fornece até oito placas PCI Ethernet virtuais para cada máquina virtual."
"Quatro das placas de rede podem ser configuradas na seção Rede da caixa de diálogo Configurações na interface gráfica do usuário do VirtualBox. Você pode configurar todas as oito placas de rede na linha de comando usando VBoxManage modifyvm."

https://www.virtualbox.org/manual/ch03.html#settings-network

Para trabalhar na linha de comando com o VB, faça o seguinte:
Abra o terminal no sistema host. Procure o arquivo virtualbox:
# find / | grep virtualbox
Deve estar num caminho assim, por exemplo:
/etc/oracle/virtualbox.

Daí você entra ali:
cd /caminho/caminho/virtualbox e executa os comandos vboxmanage e eles serão reconhecidos.

Eu acredito que o problema não seja no virtual box e sim no ubuntu, as outras duas vms estão rodando.... eu até fiz uma troca de placa nas configurações do vb e eles subiram normalmente.

seguindo os links enviados pelo Buckminster, não consgui nada substancial, porem há um erro qdo executo netplan try, listei abaixo:

"Eu acredito que o problema não seja no virtual box e sim no ubuntu, as outras duas vms estão rodando.... eu até fiz uma troca de placa nas configurações do vb e eles subiram normalmente."

O VB cria uma VM para cada sistema guest, então o problema pode ser na VM, coisa que não sabemos ainda, mas pode ser no Ubuntu da VM.

Veja
dhcp4: true

bind: Address already in use
netplan: fatal error: cannot bind to port 2983, is another daemon running?, exiting

Acredito que não está pegando IP, por isso que não sobe ao iniciar.
O problema é com o Netplan.

Execute no terminal do Ubuntu da VM:
# apt-get remove netplan
# apt-get install netplan.io netplan-
# netplan generate; netplan try
E veja se resolve.

Tente com o apt, mas verifique se está conectado na internet.
Caso necessário, levante o link com ip link set enp0s3 up.
E daí:
# apt update
# apt install netplan.io
# netplan generate; netplan try

Execute isso para vermos se é problema de DNS, não se preocupa que é temporário, ao reiniciar esse DNS sumirá do resolv.conf:
echo "nameserver 8.8.8.8" | sudo tee /etc/resolv.conf > /dev/null

E entre no arquivo /etc/apt/sources.list e comente a linha com esses repositórios:
http://ppa.launchpad.net/ondrej/php/ubuntu bionic InRelease
https://linux.teamviewer.com/deb stable InRelease

Daí:
$ sudo ip link set enp0s3 up
$ sudo apt clean <<< use o apt, não o apt-get.
$ sudo apt update

e veja se resolve.
Caso não resolver, reinicie esse Ubuntu e veja se a conexão volta.

Caso resolver, execute:
$ sudo apt install netplan.io
$ sudo netplan generate; netplan try

Se não tem aqueles repositórios no sources.list, ele está pegando esses repositórios de onde?
Do sistema host?
Verifique no sources.list do sistema host se tem aqueles repositórios.

Num pega do host, mas por desencargo de consiencia eu desabilitei do host e deu a mesma coisa..

nunca fiz e nem sabe se é possivel:

- teria como fazer algum reset de netplan, configuração de interfaces de rede.... tipo forçar a busca de interfaces no boot?

a muito tempo atras me deparei com isso e só foi remover 70-persistent-net.rules e reiniciar ai ele voltou


mas a partir do ubuntu 18.04 não tem mais

Sim, mas se não pega do host, ele está pegando de onde esses repositórios?
O sources.list é único e um dos problemas acredito que está aí. Quando tenta dar o apt update ele está usando aqueles repositórios que não são dele, isso bagunça o sistema.
Verifique se tem o diretório /etc/apt/sources.list.d, se tiver, veja o que tem dentro.

Dê um cd em /run/systemd/network/
$ cd /run/systemd/network/
$ ls
deve ter algo parecido como 10-netplan-enp0s3.network
$ cat 10-netplan-enp0s3.network
para ver o que tem dentro.

No arquivo /etc/netplan/*.yaml comente as configurações que tem lá e coloque abaixo essas, vamos testar com esse Ubuntu em Bridge em vez de NAT. Depois é só desfazer a configuração se não der certo.
Coloque o que está abaixo dentro do arquivo:



Note que as linhas do arquivo são identadas – é importante prestar atenção a isso, ou a configuração não terá efeito. E a identação deve ser feita com espaços, e não tecla tab.
Aqui no forum não aceita espaços nem tab. Veja no link a identação na seção Configuring network bridges:
https://netplan.io/examples/
http://www.bosontreinamentos.com.br/linux/como-configurar-endereco-ip-estatico-no-linux-ubuntu-18-04...

Salve e saia do arquivo e execute:
$ netplan apply
e veja se retorna mensagem de erro.
