:SELinux is preventing /usr/sbin/dnsmasq from 'read' accesses on the lnk_file /var/lib/libvirt.
:*****  Plugin catchall (100. confidence) suggests  ***************************
:If you believe that dnsmasq should be allowed read access on the libvirt lnk_file by default.
:Then you should report this as a bug.
:You can generate a local policy module to allow this access.
:allow this access for now by executing:
:# grep dnsmasq /var/log/audit/audit.log | audit2allow -M mypol
:# semodule -i mypol.pp
