Como recuperar o módulo kvm acidentalmente removido

Question

Eu acidentalmente fiz modprobe -r kvm mas não consegui recuperar o kvm. tentei instalar de volta por yum install kvm ele instalou qemu-system-x86.x86_64 2: 2.0.0-1.el7.6.

mas ainda assim não funciona.

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

Answer 1

O oposto de modprobe -r kvm é modprobe kvm , mas sua saída lsmod indica que o módulo kvm kermel já está carregado.

Seu problema provavelmente é da segunda saída que você incluiu, especificamente:

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