Re: [Lxc-users] lxc container messing with hosts networking
Not sure if I got it right but seems to me that you are speaking about hardware bridges and not about the software ones we are testing here with the kvm stuff. Besides, looks like Serge reported it working properly on his natty-natty setup, I wonder if it happens the same with the setup I provided.

On Cisco for instance, there will be a notable connection lag on topologie changes if a link isn't configured to use a certain fast option.

I don't think you have to have something in mind to implement this. Just that old motto Be lenient in what you accept :). So if I type 'lcx.' instead of 'lxc.', as I often do, it'll silently ignore it? No, that's a bad idea. In any case I wasn't (until now) doubting Daniel's motivations, rather I was pretty sure he had something neat in mind. I like it but I can't think of anything off hand that I'd use it for that I couldn't just as easily use either comments or a separate file to do. And obviously as you point out there's an argument for enforcing only known options as a basic sanity check. On the other hand there have been plenty of times where I wished something would gracefully ignore options it didn't recognize which came from newer versions or from distribution patched versions. It gets in Note that this patch won't make a difference for unrecognized, newer lxc.* options anyway :) It would however allow for interspersed 'libvirt.*' options, for instance, to support inline hints for a new libvirt-lxc2 driver. Probably not what Daniel is looking to, but not impossible :) -serge -- Achieve unprecedented app performance and reliability What every C/C++ and Fortran developer should know.

Nice! but I don't believe it is just a kvm issue if you are suggesting this, as it happened to me on a standard debian on a laptop over a wireless link, br0 to wlan0 etc... and had same hang. Any ideas what could be causing it? it has to be something on the host system.
