KVM localhost(qemu)--connecting卡死 KVM localhost(qemu)-connecting卡死 参考文档: http://wiki.libvirt.org/page/Failed_to_connect_to_the_hypervisor https://access.redhat.com/knowledge/docs/en-US/Red_Hat_Enterprise_Linux/6/html/6.3_Technical_Notes/libvirt.html https://access.redhat.com/knowledge/docs/en-US/Red_Hat_Enterprise_Linux/6/html/Virtualization_Host_Configuration_and_Guest_Installation_Guide/App_TCP_Ports.html 场景:VM workstation12安装Ubuntu12.04 x64跟kvm 现象:virsh命令直接卡死,virt-manager提示“没有活跃连接可用于安装",关机重启命令无效只能断电 原因:libvirtd调用子进程dmidecode超时至无法响应,可能和VM workstation的兼容性有关 解决办法:killall dmidecode 杀掉dmidecode后,kvm立马就正常了,关机重启也正常了
