为一个虚拟机分配 2 个 IP 地址

我想为一个虚拟机分配 2 个 IP 地址，但无法实现。我有

IP              MAC
151.180.39.138   02:aa:cc:73:b1:39
78.132.120.30   02:cc:aa:79:fb:e7

/etc/网络/接口

auto eth0
iface eth0 inet static
        address 151.180.39.138
        netmask 255.255.255.0
        broadcast 151.180.39.138
        dns-nameservers 8.8.8.8
        dns-search server3
        pre-up ifconfig eth0 hw ether 02:aa:cc:73:b1:39
        post-up route add 137.159.142.254 dev eth0
        post-up route add default gw 137.159.142.254
        pre-down route del 137.159.142.254 dev eth0
        pre-down route del default gw 137.159.142.254

auto eth1
iface eth1 inet static
       address 78.132.120.30
       netmask 255.255.255.0
       broadcast 78.132.120.30
       dns-nameservers 8.8.8.8
       post-up route add 137.159.142.254 dev eth1

是否配置

我在配置文件中有两个接口，当我执行 virsh edit server3 时，我可以看到

<interface type='bridge'>
  <mac address='02:aa:cc:73:b1:39'/>
  <source bridge='br0'/>
  <model type='virtio'/>
  <address type='pci' domain='0x0000' bus='0x00' slot='0x03' function='0x0'/>
</interface>
<interface type='bridge'>
  <mac address='02:cc:aa:79:fb:e7'/>
  <source bridge='br0'/>
  <model type='virtio'/>
  <address type='pci' domain='0x0000' bus='0x00' slot='0x05' function='0x0'/>
</interface>

如何使其工作，以便我可以访问两个 IP 地址，因为目前第二个 IP 地址无法访问。
