[pve-devel] More than 10 interfaces in lxc containers

Hi Dietmar,

To explain a little more. The OVH servers are just rented hardware 
somewhere in a datacenter of OVH.

I have no control over switching, etc. All networking is 'internal'. See 
the attached drawing.

Probably, it is what was on your mind. But I think it's good for me to 
explain as clearly as possible.

And - again - if I am not educated enough about how to use traditional 
vmbr setups as a vlan trunk, then any pointer to information is welcome.

Kind regards,
