Thanks for reporting this. Please note that libvirt-lxc driver has been deprecated since rhel-7.1. See https://access.redhat.com/articles/1365153.

Moving to the upstream product.

FWIW I see this on f24, but not on f23, even with libvirt git.

The referenced XML is:

<domain type='lxc'>

By using Cole's XML and libvirt master (8ed874b39b3c330bbcdff434e08995dbb4467285), the message is not there anymore:

./tools/virsh --connect lxc:/// console bash              
Connected to domain bash
Escape character is ^]
sh-4.4# exit

./tools/virsh --connect lxc:/// version     
Compiled against library: libvirt 4.6.0
Using library: libvirt 4.6.0
Using API: LXC 4.6.0
Running hypervisor: LXC 4.17.3

So Cole, do you think this bug can be closed?
