Re: [Lxc-users] Bonding inside LXC container
Hi Jake, First of all, thank you for your reply and I am very sorry for such a late response. Just as you said, I had ever tried the bonding style like this: eth0--+--bound0--[veth]--eth0 eth1--/ But when I used mode=6(alb) of bonding following this way, there is 80% packet loss in the container, I must patch the kernel to the problem. On the other hand, my current approach: eth0--[phys]--eth0--+--bound0 eth1--[phys]--eth1--/ My lxc configuration like this (Networking part) : *# Networkinglxc.network.type = macvlanlxc.network.flags = uplxc.network.link = eth0lxc.network.name http://lxc.network.name = eth0lxc.network.ipv4 = 172.19.8.168/16 http://172.19.8.168/16lxc.network.mtu = 1500lxc.network.hwaddr = fe:67:f5:42:40:14* *lxc.network.type = macvlanlxc.network.flags = uplxc.network.link = eth1lxc.network.name http://lxc.network.name = eth1lxc.network.ipv4 = 172.19.8.169/16 http://172.19.8.169/16lxc.network.mtu = 1500lxc.network.hwaddr = fe:67:f5:42:40:15* *...* I did the bonding in the container, the bonding configuration is the same as what I did before on the host. When I started bonding device in the container, this message came out: Bringing up interface bond0: bonding device bond0 does not seem to be present, delaying initialization. I'm not sure but I doubt it may be Network namespace or something similar that brings about this problem. What's your idea?

I ended up getting the ppa daily build (because I like living dangerously) and setting up kernel 3.11.0 from Ubuntu Saucy. To be honest I'm not expecting amazing performance here with my environment. I'm running on Xen-PV using PV-Grub (PyGrub is a more common name for it I think). The kernel is running through that setup as the host provided kernels don't have the necessary supports enabled. Prior testing showed that LXC is viable in the environment and worked in the past but bridging won't work due to the way the host has their switches setup (no foreign mac addresses are allowed...) so it will be nat only for me. -- DreamFactory - Open Source REST JSON Services for HTML5 Native Apps OAuth, Users, Roles, SQL, NoSQL, BLOB Storage and External API Access Free app hosting.

Re: [Lxc-users] Bonding inside LXC container
Dear Yao, I have no experience with the macvlan device because I even can't find a clear documentation and I wonder if there is one her to give an abstract and howto for it. In my diagram I meant to use lxc.network.type = phys to directly reach through the NIC device. Reading https://www.kernel.org/doc/Documentation/networking/bonding.txt i got the notion that the bonding driver is strongly related to the physical network drivers. I don't think that it will work with virtual devices like macvlan or even veth as basic devices, but I may be wrong with this. I'm not sure but I doubt it may be Network namespace or something similar that brings about this problem. I was able to google out a thread Bonding simplifications and netns support on the kernel.org mailing list. It's from end of 2009 but I think it's irrelevant nowadays. -Original Message- From: wang yao [mailto:yaowang2...@gmail.com] Sent: Monday, November 18, 2013 5:09 AM To: Jäkel, Guido Cc: lxc-users@lists.sourceforge.net Subject: Re: [Lxc-users] Bonding inside LXC container Hi Jake, First of all, thank you for your reply and I am very sorry for such a late response.
