为什么我的机器只能开5个kvm虚拟机
24G的机器
root@puppetnode01 ~]# free -m total used free shared buffers cached Mem: 24020 21869 2150 0 188 17821 -/+ buffers/cache: 3859 20160 Swap: 32767 168 32599
在跑5个了

每个kvm虚拟机是512m的而已

当我要新启动一个机器，就出现以下错误：
[root@puppetnode01 ~]# virsh start redis_01 error: Failed to start domain redis_01 error: Unable to read from monitor: Connection reset by peer
我随便关掉一个在运行的虚拟机后，然后在启动新的就正常启动了，这是什么情况的。
