KVM: у centos нет мостового IP-адреса на Fedora
Я установил на своей машине с Fedora centos как vm поверх kvm. Моя виртуальная машина не получает IP-адрес от моего DHCP-сервера через интерфейс моста. Когда я хочу активировать интерфейс через nmtui на моей машине centos я получаю следующую ошибку:
В моей хост-системе я использую вместо этого NetworkManager systemd-networkd для создания интерфейса моста для моей виртуальной машины. Пример удара - это отрывки из моей конфигурации systemd-networkd.

Я надеюсь, что у кого-то есть идея, почему я не получаю IP-адрес через интерфейс моста от хост-системы.
