Hi Thomas
I had a brief look at the network manager source code that is in the
Ubuntu repositories. While I am no developer, I do see that there are
numerous references to VLAN in the code.
I also see that concerning the plugins only the rhel parser has vlan
references, not the ifupdown.
My current take is thus that network manager does have VLAN support in
Ubuntu (if it hasn't been disabled somewhere), but you cannot use the
/etc/network/interfaces file for these. The "keyfiles" in
/etc/NetworkManager/system-connections/, however, could well be usable,
if someone finds out, how to configure a vlan there...

Title:
NetworkManager tries to configure eth0 instead of eth0.1
Status in “network-manager” package in Ubuntu:
Incomplete
Bug description:
System Ubuntu 12.04 LTS (precise), network-manager 0.9.4.0-0ubuntu4.1
I have the following configuration in /etc/network/interfaces:
auto lo
iface lo inet loopback
# The primary network interface
#auto eth0
auto eth0.1
The nm-applet shows this connection as "ifupdown(eth0.1)" correctly,
although this can of course not be edited.
However, when activating this connection, network-manager activates
eth0 instead of eth0.1, which of course does not work. Here is the
relevant syslog:

As you can see, it is really not activating eth0.1 as written in
/etc/nbetwork/interfaces but eth0, although network manager 0.9.4 should have
support for vlan configurations.
If I am doing something wrong, please tell me what and how it should
be done instead.
Thank you very much.
