I meant that there is a container which runs in host networking mode, and it runs OVS server and neutron agents (the L3, DHCP and metadata agents).
I attached to the container directly and I used bash instead of sh. But it did not work on my setup, there were similar errors in vswitchd logs as I posted in an earlier email. I did see a permission denied while trying to set ulimit in the init script, even though it was being run as root. The services started up fine. cloudscaling@mngmt2:~/> docker run -it --pid=host --net=host ubuntu bash root@mngmt2:/# apt-get update Ign http://archive.ubuntu.com trusty InRelease Ign http://archive.ubuntu.com trusty-updates InRelease Ign http://archive.ubuntu.com trusty-security InRelease Hit http://archive.ubuntu.com trusty Release.gpg Get:1 http://archive.ubuntu.com trusty-updates Release.gpg [933 B] Get:2 http://archive.ubuntu.com trusty-security Release.gpg [933 B] Hit http://archive.ubuntu.com trusty Release Get:3 http://archive.ubuntu.com trusty-updates Release [62.0 kB] Get:4 http://archive.ubuntu.com trusty-security Release [62.0 kB] Get:5 http://archive.ubuntu.com trusty/main Sources [1335 kB] Get:6 http://archive.ubuntu.com trusty/restricted Sources [5335 B] Get:7 http://archive.ubuntu.com trusty/universe Sources [7926 kB] Get:8 http://archive.ubuntu.com trusty/main amd64 Packages [1743 kB] Get:9 http://archive.ubuntu.com trusty/restricted amd64 Packages [16.0 kB] Get:10 http://archive.ubuntu.com trusty/universe amd64 Packages [7589 kB] Get:11 http://archive.ubuntu.com trusty-updates/main Sources [229 kB] Get:12 http://archive.ubuntu.com trusty-updates/restricted Sources [1874 B] Get:13 http://archive.ubuntu.com trusty-updates/universe Sources [130 kB] Get:14 http://archive.ubuntu.com trusty-updates/main amd64 Packages [557 kB] Get:15 http://archive.ubuntu.com trusty-updates/restricted amd64 Packages [14.8 kB] Get:16 http://archive.ubuntu.com trusty-updates/universe amd64 Packages [329 kB] Get:17 http://archive.ubuntu.com trusty-security/main Sources [86.9 kB] Get:18 http://archive.ubuntu.com trusty-security/restricted Sources [1874 B] Get:19 http://archive.ubuntu.com trusty-security/universe Sources [19.6 kB] Get:20 http://archive.ubuntu.com trusty-security/main amd64 Packages [269 kB] Get:21 http://archive.ubuntu.com trusty-security/restricted amd64 Packages [14.8 kB] Get:22 http://archive.ubuntu.com trusty-security/universe amd64 Packages [113 kB] Fetched 20.5 MB in 13s (1515 kB/s) Reading package lists...
