[Lxc-users] problem in start lxc container

[Binknight]

hi Fajar,


    thank you for your advise and wiki, that provides a lot of useful informations.


    My test environment is FC16 and product environment is centos 6.3. So I have to set up lxc in FC or centos. I tested in centos and found that lxc-0.7.5 will work(I previously use the 0.8.0rc). Now I can ping the host from my container and vice versa, but I can not access to other networks(eg. ping www.google.com will fail). My network configure is,


lxc.network.type = veth
lxc.network.flags = up 
lxc.network.link = virbr0 
lxc.network.name = eth0 
lxc.network.mtu = 1500 
lxc.network.ipv4 = 192.168.122.2/24


the bridge "virbr0" is create automatically by install libvirt.
