Eu tenho o Dell t5500 que eu propus como um servidor. Tem uma porta ethernet (enp6so). Eu adicionei um segundo NIC para obter uma segunda porta (10 GBE) (virbr0).
Não é plug and play, infelizmente. Eu não posso fazer o virbr0 funcionar. Não tenho certeza do que fazer agora.
ifconfig (o virbr0 não é 'RUNNING')

Eu testei ifconfib virbr0 e isso não tem efeito.
Não tenho certeza do que tentar agora.
