I have the "message truncated" warning when I have defined around 1800vlans. (can be 1-1800 on 1 interface, or 1-900 + 1-900 on 2 interfaces,...).

Still no luck with kernel 4.1. 

I could limit the number of vlans, with adding dynamicaly to ethX|bondX vlans to allow, when the vm is starting. 

If user want to tag inside the vm, we could add an option "vlans filter" or something like that.

The manual way works for me on my host. The /etc/network/interfaces way 
doesn't. Presumably because I didn't `apt-get purge vlan`. 
In my test VMs where I purged vlan and pve-manager and reinstalled the 
patched pve-manager it all works fine. 

What I really hate about this is the whole "Message truncated" issue, as 
this doesn't only apply to the output of `bridge vlan show`, but also if 
I add vlans 2-4094 to my test dummy interface dum0, both the testbridge 
and dum0 interface disappear even from the output of `ip link` which 
also throws that error. This is highly annoying.
