Unable to read from monitor: Connection reset by peer

今天看到KVM里虚拟机报错如下

Unable to read from monitor: Connection reset by peer

具体如图

错误原因可能是对网卡做了改动，昨天对网卡做了绑定，目前网卡信息就比较复杂了。导致KVM正在运行的虚拟机突然停止了，RESTORE就出现了如图的信息。

解决方案就是把restore移除先，再启动虚拟机

# virsh start Monitor

错误：开始域 Monitor 失败

错误：Unable to read from monitor: Connection reset by peer

# virsh  managedsave-remove Monitor

Removed managedsave image for domain Monitor

# virsh start Monitor

域 Monitor 已开始
