KVM-сервер на CentOS 7, объединение 2 сетевых адаптеров и мостовая конфигурация сети vlan не работает

Я пытаюсь установить CentOS 7 на сервере для размещения виртуальных машин через KVM. Сеть, которую я пытаюсь настроить, должна позволять использовать несколько виртуальных локальных сетей для двух сетевых адаптеров через соединение / мост. Это вообще не работает. Я не могу понять, что делаю не так. Может ли кто-нибудь указать мне правильное направление?
