So, does the command "ifconfig eth1.35 down" cause the message "unregister_vlan_device: ERROR: Tried to remove a non-vlan device with VLAN code, name: eth1.35 priv_flags: 0" or this message doesn't appear.
You have shown strace output of that command

I haven't been able to find anything related to VLAN.

ifdown, ifconfig and ip l set down reproduce this issue, but "unregister_vlan_device: ERROR: ..." appear only with ifdown
"/etc/init.d/networking stop" uses ifdown
so maybe it's not vlan related, and I'm working on the wrong way.

What's the difference between strace "ifconfig eth1.35 down" and "ifconfig eth1 down" (after eth1.35 rename to eth1)? Why the second case doesn't break the system? Where is the difference in strace output?
|
If I had the response...
there are no big diff between the 2 straces... ifconfig down does not break directly nfs export I guess, but by shutdown the interface (whatever the way to set down), something is broken in kernel land. If not, I can't see how an action inside a VE can affect another VE.

I think this sort of investigation could help us. It's the good for us to understand the difference between the "good" and the "bad" cases.
