如何恢复意外删除的 kvm 模块

我意外地这样做了modprobe -r kvm但无法让 kvm 恢复工作。尝试通过yum install kvm安装 qemu-system-x86.x86_64 2:2.0.0-1.el7.6 来重新安装它。

但它仍然不起作用。

[root@centos ~]# lsmod  | grep kvm
kvm                   525409  0

答案1

的反义词modprobe -r kvm是modprobe kvm，但是您的lsmod输出表明kvm kermel模块已加载。

您的问题可能来自您所包含的第二个输出，具体来说：

cannot open path '/home/mukesh/Downloads/LabIPA-small': No such file or directory
