I hope this question isn't considered too off topic for this list, I am trying to reach the libvirt-sandbox developers, but I could not find a libvirt-sandbox specific mailing list, and it seemed to me that libvirt-sandbox was a part of libvirt itself.

I am trying to port libvirt-sandbox to run on a CentOS 6.5 system. This wasn't too hard but, I had to do the following:

I have used the CentOS repo addon ElRepo to upgrade the kernel to 3.10.28. CentOS normally runs a 2.6.32 kernel.

I upgraded glib2 from 2.36 to 2.38.2. I did this by building 2.38.2 from source and installing it into /usr/local. Thus, the 2.36 version still exists in /lib64 and the normal CentOS applications use this version.

I built libvirt 1.2.1 from source and installed it into /usr/local. I used:
     ./configure --with-lxc --with-selinux --with-secdriver-selinux --prefix=/usr/local

I built libvirt-glib 0.1.7 from source and installed it into /usr/local. I used:
    PKG_CONFIG_PATH=/usr/local/lib/pkgconfig ./configure --prefix=/usr/local

I build libvirt-sandbox 0.5.1 from source and installed it into /usr/local. I used:
    PKG_CONFIG_PATH=/usr/local/lib/pkgconfig ./configure

As a test, I am able to run the libvirt lxc helloworld example:

[root@scwnet1 lxc_helloworld]# virsh -c lxc:/// define helloworld.xml
Domain helloworld defined from helloworld.xml

[root@scwnet1 lxc_helloworld]# virsh -c lxc:/// start helloworld
Domain helloworld started

[root@scwnet1 lxc_helloworld]# virsh -c lxc:/// list
 Id    Name                           State
----------------------------------------------------
 9819  helloworld                     running

[root@scwnet1 lxc_helloworld]# virsh -c lxc:/// console helloworld
Connected to domain helloworld
Escape character is ^]
sh-4.1# exit
exit


Next, I try to use libvirt-sandbox, and I get the following error:
[root@scwnet1 tests]# /usr/local/bin/virt-sandbox -c lxc:/// /bin/sh
Unable to start sandbox: Failed to create domain: unsupported configuration: Unable to find security driver for label selinux


My libvirt config.log shows the SELinux security driver as yes:

I am not sure if secmodel none is the problem.

Can someone give me some direction on how to fix this?
