[lxc-users] Networking macvlan has a low limit

[CDR]

I have reached a vey low limit on a macvlan network. One physical
interface, eth0, returns an error

lxc_conf - failed to set 'eth1' up : Device or resource busy
      lxc-start 1413870325.642 ERROR    lxc_conf - failed to setup netdev
      lxc-start 1413870325.642 ERROR    lxc_conf - failed to setup the
network for 'dialer-9'
      lxc-start 1413870325.642 ERROR    lxc_start - failed to setup
the container
      lxc-start 1413870325.642 ERROR    lxc_sync - invalid sequence
number 1. expected 2

lxc.network.type = macvlan
lxc.network.macvlan.mode=bridge
lxc.network.flags = up
lxc.network.link = eth0
lxc.network.name= eth1
lxc.network.hwaddr = 00:16:3e:08:92:c4
lxc.network.ipv4 = 0.0.0.0/24


This happens after I start 6 containers only, sharing the same interface eth0.
How do I start more containers using the same interface and macvlan?
Note: this ubuntu 14.04 fully updated and LXC daily.
