I just had this problem, in my /var/lib/lxc/oldfront2/config I have
…
lxc.network.type = veth
lxc.network.name = veth0
lxc.network.veth.pair = veth0oldfront2
…
lxc.network.type = veth
lxc.network.name = veth1
lxc.network.veth.pair = veth1oldfront2
I stopped the VM, and then when I want to start it I have
lxc-start 20161122192407.302 ERROR lxc_conf -

ifconfig <any of these interfaces>
reports
veth0oldfront2: error fetching interface information: Device not found
As a workaround I rename these 2 interfaces in /var/lib/lxc/oldfront2/config
(adding a suffix), and lxc-start was fine then.
