Description of problem:
Running Fedora-18 inside LXC container
SELinux is preventing /usr/lib/systemd/systemd-logind from 'create' accesses on the fifo_file c2.ref.

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

If you believe that systemd-logind should be allowed create access on the c2.ref fifo_file by default.
Then you should report this as a bug.
You can generate a local policy module to allow this access.
Do
allow this access for now by executing:
# grep systemd-logind /var/log/audit/audit.log | audit2allow -M mypol
# semodule -i mypol.pp

Comment 1 Daniel Walsh 2013-05-09 14:54:14 EDT
If you are going to play with virt-sandbox or libvirt-lxc, could you try it on a newer fedora, preferably F19.  There are lots of fixes there that will not likely get back ported to F17.
