Question

我对libvirtd有问题，即使运行systemctl启动libvirtd.service，服务也是不活动的。

我是libvirt和kvm的成员。

systemctl status libvirtd的输出是

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)

以及运行其他命令(如virsh list )时的错误

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

目录/var/run/libvirt/不包含文件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libvirt0 system qemu-kvm libvirt0桥-utils virt管理器qemu libvirt0。

我试过使用systemctl enable libvirtd和systemctl enable libvirtd，但是不活动。

运行journalctl -f时systemctl restart libvirtd的输出

etc/libvirt/qemu.conf中的412行

group=kvm

这个问题有什么解决办法吗？谢谢!

Answer 1

你安装了kvm吗？要安装libvirt和kvm，请在下面运行

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

sudo systemctl enable libvirtd
sudo systemctl start libvirtd

我注意到在你的输出中缺少退潮。您可以通过运行以下命令安装它们：

sudo apt install -y ebtables

然后重新启动服务。希望这能帮到你。

Answer 2

尝试以下步骤：

sudo setfacl -m user:$USER:rw /var/run/libvirt/libvirt-sock

退出会话，然后再次登录，

sudo systemctl enable libvirtd
sudo systemctl start libvirtd
