Ubtunu下的Qemu/KVM客户机获取主机网段地址

懒得看，直接上命令

bridge link
nmcli con show | egrep 'br0|bridge-slave'
ip -br addr
sudo nano /etc/netplan/*.yaml # should be 01-network-manager-all.yaml
sudo chmod 600 /etc/netplan/01-network-manager-all.yaml
sudo chown root:root /etc/netplan/01-network-manager-all.yaml
sudo netplan generate
sudo netplan apply
nmcli dev status
ip link show br0

/etc/netplan/01-network-manager-all.yaml
network:
  version: 2
  renderer: NetworkManager

  ethernets:
    enp2s0:
      dhcp4: no
      dhcp6: no

  bridges:
    br0:
      interfaces: [enp2s0]
      dhcp4: yes
      dhcp6: yes

最后得到br0塞进去就行了
