[lxc-users] re lxcbr0 doesn't exist after upgrade to 15.10

2015-11-12 Thread mikael.pahmp 
Hi, I also got this problem after upgrading to 15.10. According to 
https://bugs.launchpad.net/ubuntu/+source/network-manager/+bug/1512749 this 
problem was fixed in 
network-manager (1.0.4-0ubuntu5.1) but I still have no lxcbr0.

Running "sudo systemctl status lxc-net" I get the following:

Any ideas what could be the problem?

Note that the fix only works after a reboot, so make sure you reboot
after updating Network Manager.

However your error looks more like a conflicting DNS or DHCP server
being installed on your machine and already binding the ports needed by
lxc-net.

Looks like you have  bind9 listening on all ipv6 interfaces, so that
the dnsmasq which lxc-net starts up cannot listen on lxcbr0.

Hello.

This problem fixed by itself. Today I re-enabled systemd and after a
reboot lxcbr0 is up and running again.

Maybe this update has something to do with it:

Can you open a launchpad bug and describe there the system you upgraded
from?  (i.e. was it stock 14.04 with systemd?  desktop, with network-manager?
/etc/network/interfaces contents;  and what do you get when you run

[lxc-users] re lxcbr0 doesn't exist after upgrade to 15.10

2015-10-26 Thread brian mullan 
Norberto

Great coincidence as I read your msg to the lxc-users list about the lxcbr0
bridge
disappearing after upgrade to Ubuntu 15.10.

I just finished upgrading one of my machines to 15.10 this weekend and
today I noticed
I couldn't start any containers.

Then I noticed there is no lxcbr0 any longer.

I followed same steps as you w/ service lxc-net stop/start etc also.

I looked on launchpad for any bugs files on lxc for this but didn't spot
anything yet however
there were several mentions of one or more systemd problems
