1、 在kvm虚拟机中执行以下命令systemctlstartserial-getty@ttyS0.servicesystemctlenableserial-getty@TtyS0.service二。在KVM物理计算机中连接[root@192-168-5-25~]#virshconsolenode-192.168.5.69-心轴连接到域节点-192.168.5。
一、在kvm虚拟机中执行如下命令
systemctl start serial-getty@ttyS0.service
systemctl enable serial-getty@ttyS0.service二、在KVM物理机中进行连接
[root@192-168-5-25 ~]# virsh console node-192.168.5.69-Harbor Connected to domain node-192.168.5.69-Harbor Escape character is ^] CentOS Linux 7 (Core) Kernel 3.10.0-327.el7.x86_64 on an x86_64 k8s-harbor login: root Password: Last login: Thu Sep 5 15:57:10 on ttyS0 [root@k8s-harbor ~]#
按ctrl+]退出登录
