Thank you! Yes, you are right, eth0 says dhcp inside container - but where did that come from? I have statically added the IP in the container config file.. Is there any way I can add the stuff you mentioned in /etc/network/interfaces before starting the container, for e.g., in the container confi

Oh, I should have read your config a bit more closely :) Anyway, your problem is probably that /etc/network/interfaces in the container still says that eth0 is to be configured by dhcp. You should either put your IP configuration in the container config or in the container itself using the distro

Veth interface does get added to the br-int. It gets the IP 172.16.0.2 that it was given in the config file. On the container ifconfig eth0 shows: ubuntu@vpfe:~$ ifconfig eth0 eth0 Link encap:Ethernet HWaddr 00:16:3e:4c:45:ae inet addr:172.16.0.2 Bcast:172.255.255.255 Mask:255.0.

I did this by calling __lxc_start(). So, lxc_check_inherited() didn't get called. That was this: > If I call __lxc_start() rather than lxc_start(), I see this: > vdr1: sync wake failure : Broken pipe > vdr1: failed to spawn 'vdr1' > And, just before that there is some complaining from valgrind:

If it takes along time to boot then it likely isn't getting an ip address from dnmasq. Now last I checked br-int does have a dnsmasq running, but double-check that. You can lxc-attach to the container and manually do sudo dhclient eth0 This is assuming that you are on a new enough lxc so that th

Hi, For the sake of testing I'd go ahead and just 'return 0' at the top of lxc_check_inherited. We can talk about adding an option to do this, i.e. lxc.close_all_fds = -1 maybe. It's a very rare case where that should be done, though. -serge Quoting Vallevand, Mark K (mark.vallev...@unisys.com
