Description Christian Stadelmann 2015-10-23 16:10:11 UTC
Version-Release number of selected component (if applicable):
libvirt-daemon-1.2.13.1-3.fc22.x86_64

How reproducible:
always

Steps to Reproduce:
1. install libvirt with some but not all connection drivers
2. reboot
3. watch syslog

Actual results:
You'll see entries like these:
Module /usr/lib64/libvirt/connection-driver/libvirt_driver_libxl.so not accessible
Module /usr/lib64/libvirt/connection-driver/libvirt_driver_lxc.so not accessible
Module /usr/lib64/libvirt/connection-driver/libvirt_driver_uml.so not accessible
Module /usr/lib64/libvirt/connection-driver/libvirt_driver_vbox.so not accessible

Expected results:
No warnings. I didn't install those drivers. Libvirt doesn't depend on these, so it should not warn.

Additional info:
This issue is present since libvirt 1.2.13.1-2.fc22 at least.

Comment 1 Cole Robinson 2015-10-23 17:24:45 UTC
Still in libvirt.git. We should make it VIR_INFO or VIR_DEBUG IMO


$ git grep --context=10 -n "Module %s not"
src/driver.c-55-
src/driver.c-56-    if (!(modfile = virFileFindResourceFull(name,
src/driver.c-57-                                            "libvirt_driver_",
