[ovs-discuss] LXC and OpenVSwitch on Ubuntu 12.10

[Jon]

Hello,

I'm experiencing the same issues as described in a previous thread,
http://openvswitch.org/pipermail/discuss/2012-June/007459.html

unfortunately, that thread kinda died without a resolution.

I followed these instructions to setup ovs and kvm on the host,

>>
http://blog.allanglesit.com/2012/10/linux-kvm-ubuntu-12-10-with-openvswitch/

however, I did not install the ovs-brcompat package.

KVM works beautifully with ovs (though I'm having some trouble with
OpenNebula and ovs, but I have an issue open with them,
http://www.mail-archive.com/users@lists.opennebula.org/msg10021.html I only
bring it up because I think ovs is configured correctly as I am able to get
vms connected when using libvirt / virsh xml templates)

My lxc config looks like this: (gateway is 55.55.55.65, 55.55.55.66 is my
host)

>> lxc.utsname = mysandbox
>> lxc.network.type = veth
>> lxc.network.flags = up
>> lxc.network.mtu = 1500
>> lxc.network.link = ovsbr0
>> lxc.network.script.up=/etc/lxc/ovsup
>> # As appropiate (line only needed if you wish to dhcp later. To be
unique)
>> #lxc.network.hwaddr =  00:FF:08:5E:00:01
>> # (Use 0.0.0.0 if you wish to dhcp later)
>> lxc.network.ipv4 = 55.55.55.67/28
>> # could likely be whatever you want
>> lxc.network.name = eth0
>> lxc.mount = /lxc/mysandbox/fstab
>> lxc.rootfs = /lxc/mysandbox/rootfs
>> lxc.tty = 2

When I attempt to start my container:

>> lxc-start -l DEBUG -d --name mysandbox -f /lxc/mysandbox/config -o
lxc.log

I get the following error log:

>>       lxc-start 1364869829.848 DEBUG    lxc_conf - allocated pty

I also experience the same symptoms as described by the original reporter:

>>  root at loki:~# brctl showmacs ovsbr0
>>  read of forward table failed: Operation not supported

Any suggestions on how I can troubleshoot this issue further?

Thanks,
Jon A
