virt-manager linux上虚拟机安装错误处理：error: Failed to connect socket to '/var/run/libvirt/libvirt-sock': No

error: Failed to connect socket to '/var/run/libvirt/libvirt-sock': No such file or directory

文件有可能存在，但是找不到(我的就是这样 明明有这个文件，还说找不到，ln -s // 也不行)

我是这样处理的，1我去换成ustc的源

sudo vi /etc/apt/sources.list

deb http://debian.ustc.edu.cn/debian stable main non-free contrib

deb-src http://debian.ustc.edu.cn/debian stable main non-free contrib

deb http://debian.ustc.edu.cn/debian proposed-updates main contrib non-free

deb-src http://debian.ustc.edu.cn/debian proposed-updates main contrib non-free

deb http://debian.ustc.edu.cn/debian-security stable/updates main

deb https://mirrors.ustc.edu.cn/ubuntu/ xenial main restricted universe multiverse
# deb-src https://mirrors.ustc.edu.cn/ubuntu/ xenial main main restricted universe multiverse
deb https://mirrors.ustc.edu.cn/ubuntu/ xenial-updates main restricted universe multiverse
# deb-src https://mirrors.ustc.edu.cn/ubuntu/ xenial-updates main restricted universe multiverse
deb https://mirrors.ustc.edu.cn/ubuntu/ xenial-backports main restricted universe multiverse
# deb-src https://mirrors.ustc.edu.cn/ubuntu/ xenial-backports main restricted universe multiverse

(其他的源请自查)

2安装kvm 

sudo apt-get install kvm

3卸载virt-manager .再安装一遍(可能是以前安装的少了什么东西)

sudo apt-get autoremove virt-manager

sudo apt-get install virt-manager

4去 /var/run/libvirt  给 libvirt-sock  libvirt-sock-ro virtlockd-sock 仨文件加权限 (据说 只加libvirt-sock 就行)

sudo chmod -R 777 libvirt-sock

sudo chmod -R 777 libvirt-sock-ro

sudo chmod -R 777 virtlockd-sock

5重启服务

service libvirtd restart

6 启动 virt-manager
