项目场景：

vmware部署k8s集群，用于学习。挂起vm后重新启动，执行任何命令都报如下提示：

Unable to connect to the server: dial tcp 192.168.0.132:16443: connect: no route to host

查询显卡信息，发现虚拟ip：132未生效：

ip a s ens33
2: ens33: <BROADCAST,MULTICAST,UP,LOWER_UP> mtu 1500 qdisc pfifo_fast state UP qlen 1000
    link/ether xxxxxxxxxxxxxxxxxxxxxx
    inet 192.168.0.130/24 brd 192.168.0.255 scope global ens33
       valid_lft forever preferred_lft forever
    inet6 xxxxxxxxxxxxxxxxxxxxxx scope link 
       valid_lft forever preferred_lft forever

重启keepalived，问题解决

# systemctl restart keepalived.service
# ip a s ens33
2: ens33: <BROADCAST,MULTICAST,UP,LOWER_UP> mtu 1500 qdisc pfifo_fast state UP qlen 1000
    link/ether xxxxxxxxxxxxxxxxxxxxxx
    inet 192.168.0.130/24 brd 192.168.0.255 scope global ens33
       valid_lft forever preferred_lft forever
    inet 192.168.0.132/32 scope global ens33
       valid_lft forever preferred_lft forever
    inet6xxxxxxxxxxxxxxxxxxxxxx scope link 
       valid_lft forever preferred_lft forever
