我使用的是 CentOS 8。 我使用以下方法构建了 libvirt：
$ meson build -Dsystem=true
$ ninja -C build
$ ninja -C build install
但问题是我什么时候开始的
# systemctl start libvirtd
Job for libvirtd.service failed because the control process exited with error code.
See "systemctl status libvirtd.service" and "journalctl -xe" for details.
我试图获取 libvirt 的状态
# systemctl status libvirtd
● libvirtd.service
Loaded: not-found (Reason: Unit libvirtd.service not found.)
Active: failed (Result: exit-code)
运行时
$ ls /usr/lib/systemd/system/*virt*
输出如下图：
