Description Michal Kovarik 2014-09-15 16:02:35 UTC
Description of problem:
Start virtual machine in virt-manager. 
SELinux is preventing /usr/sbin/openvpn from 'read' accesses on the chr_file /dev/net/tun.

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

If you believe that openvpn should be allowed read access on the tun chr_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 openvpn /var/log/audit/audit.log | audit2allow -M mypol
# semodule -i mypol.pp
