<br>
I am working now with lxc/lxd in 14.04 servers, no problems with this.<br>
<br>
The problem is in my desktop machine (14.04 too), after my machine boots, i need to restart lxc-net service (sudo restart lxc-net) to have lxcbr0 device and work with lxd instances (and launch lxc instances with my user, privileged or un-privileged)<br>
<br>
i think that is a boot problem but the only related message in /var/log/syslog is:<br>
<br>
=====<br>
NetworkManager[1736]: <info> (lxcbr0): ignoring bridge not created by NetworkManager<br>
=====<br>
<br>
i have onlys dnsmasq-base in my workstation, no dnsmasq, so i think that is a config problem but i can't find now this, some help is needed<br>
<br>
P.D. i uninstall and reinstall lxc, lxd and lxd-client for testing and checks, same results.<br>
<br>
