Re: [Lxc-users] Regarding connecting containers to vlan

2012-10-31 Thread Kalyana sundaram 
Thanks Fajar. Atlast I got the vlan thingy working
I added 2 vlans to eth0 (eth0.211 and eth0.103) and connected them to
bridge br0 and used br0 as a link to container(veth)
To reach the host I used another interface eth1(probably assigning ip to
bridge br0 would have solved that problem)

i should give openvswitch a try. Thanks for the link

  I know this answer isn't about VLAN specifically but it might interest
 you.
  I'd stumbled upon it a few weeks ago and the title was
  Connecting containers on several hosts with Open vSwitch
 
 
 http://s3hh.wordpress.com/2012/05/28/connecting-containers-on-several-hosts-with-open-vswitch/
 
  There was also a newer post regarding Open vSwitch and LXC:
  http://s3hh.wordpress.com/


 Last time I tested, openvswicth is more powerful, but kinda
 complicated for new users who are used to linux bridge.

 Anyway, back to Kalyana's requirement, you can either:
 - bridge the trunk (eth0) to the container, and create vlan on the
 interface in container side (i.e. create eth0.100 in the container)
 - bridge the vlan interface (eth0.100) to the container, and use the
 interface on container side (eth0) directly as regular interface

Thanks to everyone for fixing this.

I am about to release the 0.8.0 version.

I will wait a couple of days before adding a tag and release it in case
there are some fixes to add.

Please test.

Thanks !

Wow...

Pulling for testing.  I see some stuff related to devtmpfs that relates
to the systemd / Fedora 17 issues Serge and I have been working on for
the last couple of weeks.  I'm going to test these out.  It's been an
intense couple of weeks getting THAT to work.  Even without some of the
addition tweeks that have been discussed, this is a big step forward.
I'm looking forward to 0.80.

Regards,
Mike

 I'm not sure what you mean - are you using git://github.com/lxc/lxc, or
 the tree on lxc.sf.net?

IOW, I'm not using a branch in the tree.  I'm using the main trunk.

Created my tree with -

git clone git://github.com/lxc/lxc

So the former, not the later.

   Yeah, I don't think I need to play a game like this anymore.  I'd have
   to go back through some old old E-Mails to see why I did that before.  I

   some PRIVATE thing or another.  It may not be necessary at all any
   longer.  IAC, it's minor to switch it back.  I seem to recall switching
   back and forth using bind mounts several times back when that got done
   that way.
   
   I may play with the pre-mount hook just for giggles and see how that
   might work as well.  Any idea why I was experiencing the problem with
   the mount hook when trying to populate /dev?  I know it wouldn't have
 
  The only idea I have is that perhaps your root is MS_SHARED by default?
  Can you post the script you were using and the container config?
 
 Another point on the curve...  The documentation says that pre-mount
 takes place before the mount occurs and mount takes place after the
 mount occurs.  Only problem is that pre-mount is not being recognized.

I have

 My bad, I bridged eth0.211 and eth0.103 with br0. Could I know the
 problems it would cause?


At the very least, you effectively merge vlan 211 and 103. No point in
using vlans any more.

Worst case scenario, depending on your exact config, the switch might
detect a loop and block some ports.
