我在 CentOS 7 中遇到了同样的问题。就我而言,升级device-mapper-libs
解决了问题:
yum upgrade device-mapper-libs
就我而言,通过检查以下状态给出了一些提示libvirtd
:
service libvirtd status
出现如下错误,因此如果您遇到类似问题,升级device-mapper-libs
应该会有所帮助。

为了能够virt-manager
在您想要控制(本地)的同一台计算机上正确运行,您需要安装以下软件包:
qemu-kvm qemu-img virt-manager libvirt libvirt-python python-virtinst libvirt-client virt-install virt-viewer
重新检查它们是否都正确安装在您的服务器上,或者只需运行以下语句:
# yum -y install qemu-kvm qemu-img virt-manager libvirt libvirt-python python-virtinst libvirt-client virt-install virt-viewer
如果您的系统上未安装某些描述的软件包,则会安装它们(并且将跳过现有的软件包)。
此外,还应在计算机上启用并运行以下 systemd 服务:
libvirtd.service libvirtd.socket libvirt-guests.service
祝你好运!
