Hi,

I am using *CentOS 8*. I have built *libvirt* with the following method:

$ meson build -Dsystem=true $ ninja -C build $ ninja -C build install

But the problem is when i started it

# 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. .> i tried to get the status of libvirt

# systemctl status libvirtd

libvirtd.service - Virtualization daemon Loaded: loaded (/usr/lib/systemd/system/libvirtd.service; enabled; vendor preset: enabled) Active: failed (Result: exit-code)

What will be the problem?

Well, what does the log say?

https://www.libvirt.org/kbase/debuglogs.html <https://www.libvirt.org/kbase/debuglogs.html>

I have edited /etc/libvirt/libvirtd.conf file based on https://www.libvirt.org/kbase/debuglogs.html Then restarted libvirt # systemctl restart libvirtd.service Job for libvirtd.service failed because the control process exited with error code. See "systemctl status libvirtd.service" and "journalctl -xe" for details.

There is not enough info to figure out what the problem is. Including the output of 'journalctl -xe' as suggested would be useful.

I would recommend to never to this again. In general installing upstream projects into any distribution like this is asking for a lot of trouble. The upstream project can change files owned by other packages and break them and running yum update can override anything the upstream project installed.

Ideally you want to create in case of CentOS RPM package and install that instead. If that's not possible you should install upstream project into /usr/local/ directory which distribution packages usually don't touch at all.

In case of libvirt you can do the following steps:

meson build ninja -C build dist rpmbuild -tb build/meson-dist/libvirt-{version}.tar.xz

The resulting RPMs will be in ~/rpmbuild/RPMS/{arch}/

you can install all of them but you can also install only what you are interested in.

But the problem is when i started it

# 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.

i tried to get the status of libvirt

# systemctl status libvirtd

libvirtd.service - Virtualization daemon Loaded: loaded (/usr/lib/systemd/system/libvirtd.service; enabled; vendor preset: enabled) Active: failed (Result: exit-code)

Thanks for the help in advanc....
