If I correct understand libvirt logic, libvirt make next operations
with "ip" utility (depend from lxc config):
1) # ip link add  link br0 name macvlan0 address  00:11:11:11:11:11
type macvlan mode bridge
2) # ip link set macvlan0 netns 1234
where 1234 - pid of lxc initd process
3) inside lxc - #ip link set dev  macvlan0 name eth0

If manualy run this sequence of command, we failed on step 2).
And it's work on Centos 7.0.1406
