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 1000link/ether xxxxxxxxxxxxxxxxxxxxxxinet 192.168.0.130/24 brd 192.168.0.255 scope global ens33valid_lft forever preferred_lft foreverinet6 xxxxxxxxxxxxxxxxxxxxxx scope link valid_lft forever preferred_lft forever
重启keepalived，问题解决
# systemctl restart keepalived.service
# ip a s ens33
