我遇到了 libvirtd 问题，即使我运行 systemctl start libvirtd.service，服务仍处于非活动状态。
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出现错误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。
我尝试过和systemctl enable libvirtd，systemctl enable libvirtd但是没有活动。
journalctl -f当我运行时的输出systemctl restart libvirtd

有解决这个问题的方法吗？谢谢！
答案1
您安装了 kvm 吗？要安装 libvirt 和 kvm，请尝试运行以下命令
sudo apt install qemu qemu-kvm libvirt-clients libvirt-daemon-system virtinst bridge-utils
sudo systemctl enable libvirtd
sudo systemctl start libvirtd
我注意到您的输出中缺少 ebtables。您可以通过运行以下命令来安装它们：
sudo apt install -y ebtables
然后重新启动服务。希望这对您有帮助。

请尝试以下步骤：
sudo setfacl -m user:$USER:rw /var/run/libvirt/libvirt-sock
退出会话并再次登录，
sudo systemctl enable libvirtd
sudo systemctl start libvirtd

有一次，我遇到了错误，因为 libvirt 的（至少）一部分在 systemd 中被“屏蔽”。因此，我必须找到所有部分 ( systemctl |grep virt)，检查它们是否被屏蔽 ( systemctl status ...)，然后取消屏蔽被屏蔽的部分 ( systemctl unmask ...)。我还启用并启动了它们。
