无法使用KeepAlive和VRRP设置浮动IP

我有一台ubuntu机器，上面有两个虚拟机，每个虚拟机运行一个应用程序，我需要为它们提供高可用性，所以我使用Keepalive和VRRP实现了一个浮动IP，但我无法使用虚拟IP从主机ping主虚拟机，它说目标主机无法访问

VM1的keepalived.conf：

vrrp_instance VI_1 { 
    interface enp1s0 
    state MASTER                  #BACKUP here for VM2
    virtual_router_id 51 
    priority 200                  #100 in case of VM2
    advert_int 2 
    authentication { 
        auth_type PASS
        auth_pass monkey 
    } 
    virtual_ipaddress { 
        192.168.122.150/24
    }
}

启动keepalived服务时，会显示以下消息：
