无法将套接字连接到“/var/run/libvirt/libvirt-sock”

Question

我的 libvirtd 有问题，即使我运行 systemctl start libvirtd.service，该服务也处于非活动状态。

我是 libvirt 和 kvm 的成员

的输出systemctl status libvirtd是

libvirtd.service - Virtualization daemon
   Loaded: loaded (/lib/systemd/system/libvirtd.service; enabled; vendor preset: enabled)
   Active: inactive (dead) since Tue 2020-04-07 23:44:24 -04; 8s ago
     Docs: man:libvirtd(8)
           https://libvirt.org
  Process: 19508 ExecStart=/usr/sbin/libvirtd $libvirtd_opts (code=exited, status=0/SUCCESS)
 Main PID: 19508 (code=exited, status=0/SUCCESS)

当我运行其他命令时的错误 virsh list

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

该目录/var/run/libvirt/不包含该文件libvirt-sock，我认为这是主要问题，但我不知道解决方案。

ls /var/run/libvirt
network  storage  virtlockd-sock  virtlogd-sock

我安装了 libvirt-daemon-system qemu-kvm libvirt-bin bridge-utils virt-manager qemu libvirt0。

我试着用systemctl enable libvirtd和systemctl enable libvirtd，但无效。

journalctl -f我运行时的输出systemctl restart libvirtd

第 412 行 etc/libvirt/qemu.conf

group=kvm

这个问题有什么解决方案吗？谢谢！

Answer 1

你安装kvm了吗？要安装 libivrt 和 kvm 尝试在下面运行

 sudo apt install qemu qemu-kvm libvirt-clients libvirt-daemon-system virtinst bridge-utils

 sudo systemctl enable libvirtd
 sudo systemctl start libvirtd

我注意到在您的输出中缺少 ebtables。您可以通过运行来安装它们：

 sudo  apt-get install -y ebtables

然后重启服务。希望这对你有帮助。
