:SELinux is preventing /usr/libexec/libvirt_lxc from 'create' accesses on the None selinux.
:
:*****  Plugin catchall (100. confidence) suggests  ***************************
:
:If you believe that libvirt_lxc should be allowed create access on the selinux <Unknown> 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 libvirt_lxc /var/log/audit/audit.log | audit2allow -M mypol
:# semodule -i mypol.pp

Comment 1 Daniel Walsh 2012-02-20 19:19:18 UTC
Miroslav, I think for F16 we need to make virtd_lxc_t unconfined. since we do not have this stuff working well yet.  Not sure why it is creating content in a directory labeled root_t?

running.sun do you have directories other then / labeled root_t?

ls -lZ /

commit 1b807b1f50e9f384b2227a5d0e28109b03eaadc5
Author: Miroslav Grepl <mgrepl>
Date:   Tue Feb 21 08:40:32 2012 +0000

    Make virtd_lxc_t as unconfined domain

Comment 4 running.sun 2012-02-21 14:58:13 UTC
i should have added that running the suggested commands
grep libvirt_lxc /var/log/audit/audit.log | audit2allow -M mypol
semodule -i mypol.pp
doesnt change anything.

Comment 6 running.sun 2012-02-27 15:11:01 UTC
installed http://kojipkgs.fedoraproject.org/packages/selinux-policy/3.10.0/76.fc16/noarch/ since im on fc16. The mkdir /selinux error definitely went away. 

I still cant interact with the containers in any way but lets leave this to another day, thanks everyone
