創建了橋接接口，但我無法通過它進行連接

作為序言，我嘗試在 Ubuntu Server 18.04.2 上執行此操作，該伺服器是我的 Win10 電腦上的 VirtualBox 來賓。

好吧，在我的Ubuntu 客戶機上，我正在嘗試為enp0s3（用於Internet 訪問的VirtualBox 橋接接口）和enp0s8（VirtualBox 內部網絡）創建一個橋接接口，以便我可以與KVM 客戶機共享這些接口（我正在設定一個VirtualBox 來賓內的 OpenNebula 環境）。這是我的原來的/etc/netplan/50-cloud-init.yaml：

network:
  ethernets:
    enp0s3:
      dhcp4: yes
    enp0s8:
      addresses: [192.168.1.55/24]
  version: 2

這是我的修改的/etc/netplan/50-cloud-init.yaml：

network:
  ethernets:
    enp0s3:
      dhcp4: no
      dhcp6: no
    enp0s8:
      dhcp4: no
      dhcp6: no
  version: 2
  bridges:
    br0:
      dhcp4: yes
      interfaces: [enp0s3]
    br1:
      interfaces: [enp0s8]
      addresses: [192.168.1.55/24]

但是，我現在無法透過任何這些介面進行連接。這是我的ifconfig之後：

br0: flags=4163<UP,BROADCAST,RUNNING,MULTICAST>  mtu 1500

brctl show:

br0            8000.7eece44da771    no             enp0s3
br1            8000.366a7c9d5e1d    no             enp0s8
virbr0         8000.52540093a24a    yes            virbr0-nic

我究竟做錯了什麼？為什麼 enp0s3 沒有取得 IP，為什麼我無法與 192.168.1.0/24 (enp0s8) 網路通訊？
