10:59 p.m.
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?
Cheers,
