做测试过程中被迫换电脑，但没有关掉原电脑的连接，所以用其他电脑连接测试环境时，发现之前的kvm测试环境因没有断开，无法连接： error: operation failed: Active console session exists for this domain
代码语言：javascript复制[root@bogon ~]# virsh console db11g
Connected to domain db11g
Escape character is ^]
error: operation failed: Active console session exists for this domain直接查询console相关进程并杀掉， 直接kill不成功，需要使用kill -9的方式：
代码语言：javascript复制[root@bogon ~]# ps -ef|grep console
root 11001 10035 0 08:11 pts/13 00:00:00 grep --color=auto console
root 28536 28270 0 07:52 pts/7 00:00:00 virsh console db11g
root 28643 28332 0 07:53 pts/11 00:00:00 virsh console db11gadg
root 28741 28383 0 07:53 pts/12 00:00:00 virsh console db11gcas
[root@bogon ~]# kill 28536
[root@bogon ~]# ps -ef|grep console
root 11300 10035 0 08:12 pts/13 00:00:00 grep --color=auto console
root 28536 28270 0 07:52 pts/7 00:00:00 virsh console db11g
root 28643 28332 0 07:53 pts/11 00:00:00 virsh console db11gadg
root 28741 28383 0 07:53 pts/12 00:00:00 virsh console db11gcas
[root@bogon ~]# kill -9 28536
[root@bogon ~]# ps -ef|grep console
root 11454 10035 0 08:12 pts/13 00:00:00 grep --color=auto console
root 28643 28332 0 07:53 pts/11 00:00:00 virsh console db11gadg
root 28741 28383 0 07:53 pts/12 00:00:00 virsh console db11gcas再次尝试连接OK：
代码语言：javascript复制[root@bogon ~]# virsh console db11g
Connected to domain db11g
Escape character is ^]
[root@db11g ~]#若要连接其他console也一样的操作方法。
