Re: [lxc-users] lxcbr0 failed in 14.04 (maybe a network config problem not lxc, need advise)
Still seems like voodoo... but this seems to work... not sure if the network-manager has anything to do with this or not.. but it is really odd that after two or three times with the restarting lxc-net it creates the lxcbr0 and then everything works after that. sudo systemctl stop network-manager Repeat this until it works: sudo systemctl stop lxc-net sudo systemctl start lxc-net ifconfig -a sudo systemctl start network-manager On Sun, Nov 1, 2015 at 9:19 PM, B G wrote: > I have been having similar problems after upgrading to 15.10.

Re: [lxc-users] lxcbr0 failed in 14.04 (maybe a network config problem not lxc, need advise)
I have been having similar problems after upgrading to 15.10. I just completely rebuilt the server and had exactly the same problems. I also tried uninstalling/re-installing and it didn't work... Try this: lxd uses lxcbr0 bridge by default. I've had some trouble with lxc-net under systemd as well. Can you do ifconfig -a sudo systemctl stop lxc-net sudo systemctl start lxc-net ifconfig -a and see if lxcbr0 shows up in the second ifconfig output? Found this in this thread: https://github.com/lxc/lxd/issues/543 I also have tried commenting out the dns line from the NetworkManager.conf file... It seems as if NetworkManager may also cause some conflicts... /etc/NetworkManager/NetworkManager.conf #dns=dnsmasq Then restart NetworkManager On Sun, Nov 1, 2015 at 8:24 PM, Yonsy Solis wrote: > Hi > > I am working now with lxc/lxd in 14.04 servers, no problems with this. > > 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) > > i think that is a boot problem but the only related message in > /var/log/syslog is: > > = > NetworkManager[1736]: (lxcbr0): ignoring bridge not created by > NetworkManager > = > > 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 > > P.D. i uninstall and reinstall lxc, lxd and lxd-client for testing and > checks, same results. > > > Yonsy Solis > > ___ > lxc-users mailing list > lxc-users@lists.linuxcontainers.org > http://lists.linuxcontainers.org/listinfo/lxc-users ___ lxc-users mailing list lxc-users@lists.linuxcontainers.org http://lists.linuxcontainers.org/listinfo/lxc-users
[lxc-users] lxcbr0 failed in 14.04 (maybe a network config problem not lxc, need advise)
Hi I am working now with lxc/lxd in 14.04 servers, no problems with this. 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) i think that is a boot problem but the only related message in /var/log/syslog is: = NetworkManager[1736]: (lxcbr0): ignoring bridge not created by NetworkManager = 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 P.D. i uninstall and reinstall lxc, lxd and lxd-client for testing and checks, same results.
