Description Paul Lange 2012-09-19 13:17:08 EDT
SELinux is preventing /usr/bin/qemu-system-x86_64 from write access on the file /home/paul/.libvirt/qemu/log/Fedora-18-Nightly-20120831.22-i686-Live-desktop.iso.log.

*****  Plugin restorecon (93.9 confidence) suggests  *************************

If sie möchten die Kennzeichnung korrigieren.
/home/paul/.libvirt/qemu/log/Fedora-18-Nightly-20120831.22-i686-Live-desktop.iso.log Standard-Kennzeichnung sollte svirt_home_t sein.
Then sie können restorecon ausführen.
Do
# /sbin/restorecon -v /home/paul/.libvirt/qemu/log/Fedora-18-Nightly-20120831.22-i686-Live-desktop.iso.log

*****  Plugin leaks (6.10 confidence) suggests  ******************************

If sie möchten den write Zugriff von qemu-system-x86_64,auf  Fedora-18-Nightly-20120831.22-i686-Live-desktop.iso.log file ignorieren, weil Sie glauben, dass dieser Zugriff nicht benötigt wird.
Then sie sollten dies als Fehler melden.
Um diesen Zugriff zu erlauben, können Sie ein lokales Richtlinien-Modul erstellen.
Do
# grep /usr/bin/qemu-system-x86_64 /var/log/audit/audit.log | audit2allow -D -M mypol
# semodule -i mypol.pp

*****  Plugin catchall (1.43 confidence) suggests  ***************************

If sie denken, dass qemu-system-x86_64 standardmässig erlaubt sein sollte, write Zugriff auf Fedora-18-Nightly-20120831.22-i686-Live-desktop.iso.log file zu erhalten.
Then sie sollten dies als Fehler melden.
Um diesen Zugriff zu erlauben, können Sie ein lokales Richtlinien-Modul erstellen.
Do
zugriff jetzt erlauben, indem Sie die nachfolgenden Befehle ausführen:
# grep qemu-system-x86 /var/log/audit/audit.log | audit2allow -M mypol
# semodule -i mypol.pp
