[Pkg-libvirt-maintainers] Bug#524145: libvirt0: default loglevel maybe too high

[Andreas Unterkircher]

Package: libvirt0
Version: 0.6.2-1
Severity: normal


I have several users here, each running virt-manager in their X
sessions to monitor a KVM host managed with libvirt. virt-manager
is configured to obtain all possible statistics from libvirt for
CPU- and RAM-usage as well as network- and disk-activity.

At 6:25 the logfiles in /var/log/libvirt/qemu got rotated and new,
empty logfiles get touched - about one hour later they logs in
there have grown again to ~ 500MB.

unki at srv-mfm-vm02:/var/log/libvirt/qemu$ ls -lrth
total 1.8G

Each log is full of lines with

I have not configured any of the log options in libvirtd.conf, so I
guess that the default log level is a bit to verbose.

unki at srv-mfm-vm02:~$ grep log /etc/libvirt/libvirtd.conf | grep -vE ^#
