网络服务重启失败

我在 kvm 中设置了一个 Ubuntu 16.04 服务器作为客户机。服务器使用 2 个接口：主机和桥接器

ip a
1: lo: <LOOPBACK,UP,LOWER_UP> mtu 65536 qdisc noqueue state UNKNOWN group default qlen 1
    link/loopback 00:00:00:00:00:00 brd 00:00:00:00:00:00
    inet 127.0.0.1/8 scope host lo
       valid_lft forever preferred_lft forever
    inet6 ::1/128 scope host 
       valid_lft forever preferred_lft forever
2: ens3: <BROADCAST,MULTICAST,UP,LOWER_UP> mtu 1500 qdisc pfifo_fast state UP group default qlen 1000
    link/ether 52:54:00:46:46:ba brd ff:ff:ff:ff:ff:ff
    inet 192.168.122.166/24 brd 192.168.122.255 scope global ens3
       valid_lft forever preferred_lft forever
    inet6 fe80::5054:ff:fe46:46ba/64 scope link 
       valid_lft forever preferred_lft forever
3: ens8: <BROADCAST,MULTICAST,UP,LOWER_UP> mtu 1500 qdisc pfifo_fast state UP group default qlen 1000
    link/ether 52:54:00:b9:36:a0 brd ff:ff:ff:ff:ff:ff
    inet 192.168.2.161/24 brd 192.168.2.255 scope global ens8
       valid_lft forever preferred_lft forever
    inet6 fe80::5054:ff:feb9:36a0/64 scope link 
       valid_lft forever preferred_lft forever

需要连接静态 ens8
