[lxc-users] Containers have network issues when their host uses a bonded interface

[Peter Steele]

We're having issues with networking connections in our containers when 
the host is configured with bonded interfaces. When we configure these 
same servers to run with VMs, everything works fine, but when we swap 
out the VMs for equivalently configured containers, we get all kinds of 
network connection failures between containers. The network issues go 
away when we reduce the bond to have a single member. More specifically, 
we configure our server with a host bridge (br0), where the host bridge 
links to the host's bonded interface (bond0). We've been using this 
model for years with VMs. Something isn't working quite right with 
containers though.

Is there something we need to set in our containers' config files when 
the host is setup with bonding?
