You are entirely correct, and the keyfile plugin needs much better
documentation. That said, we have been trying to consistently enhance
the syntax to be more natural.  It used to be
"192.168.2.41;24;192.168.2.1" :)

master would point to the master interface of which the vlan is a
port/slave, so that would be the bridge I think.

parent would be the physical interface which the vlan is using, which
would be p118p1.

Hmm, if there's no actual configuration for p118p1 then I don't think
you even need to define a config for it at all.  NM should be able to
handle the VLAN interface separately from the parent.

Hmm, the 'master' here is pointing to the p118p1 connection, so there's
no link between the vlan3 and the bridge at all.  I think you want
master=105acc55-5bbf-483f-95fe-a9d86a0284f2 here instead, which says
that the master interface of this interface is the bridge.  eg it makes
vlan3 a port of vmbr0.

(side-note: bonding is the same; the slave sets master to the bond
interface)

The rest looks good.  If my suggestions fail for some reason, can you
include /var/log/messages output so we can debug it further?

Thanks!
