Description of problem:
Start Fedora 22 with Xen and bridge
SELinux is preventing brctl from read, append access on the file /run/libvirt/network/nwfilter.leases.

*****  Plugin catchall (100. confidence) suggests   **************************

If вы считаете, что brctl следует разрешить доступ read append к nwfilter.leases file по умолчанию.
Then рекомендуется создать отчет об ошибке.
Чтобы разрешить доступ, можно создать локальный модуль политики.
Do
чтобы разрешить доступ, выполните:
# grep brctl /var/log/audit/audit.log | audit2allow -M mypol
# semodule -i mypol.pp
