Comment 5 for bug 1709224

I have a very trivial lxc-vm (just a shell)
lxc-vm.xml
<domain type='lxc'>
    <name>lxc-vm</name>
    <memory unit='KiB'>1048576</memory>
    <os>
        <type>exe</type>
        <init>/bin/sh</init>
    </os>
    <devices>
        <console type='pty'/>
    </devices>
</domain>

On the host that looks like:
14209 - Sl ? 0:00 /usr/lib/libvirt/libvirt_lxc --name lxc-vm --console 24 --security=apparmor
--handshake 28
14212 - Ss ? 0:00 \_ /bin/sh

I can start more from inside the shell it still exists when I drop out
(enter with virsh console and exit with the console exit key binding).

Once I virsh delete the libvirt-lxc container all processes it owned are gone.
Please can you:
1. retry with and without the ppa I provided
2. grab a full console log while you do so including your libvirt xml and post it here?
