I did look into modules, made a modeprobe tun and the behavior has
changed, so now I do get

So we see
config: PORT_DOWN
state: LINK_DOWN
which is relevant and makes me answer to you that this should not have
nothing to do with OVS.
But at may old configuration I do get:
34(tapDMZ09): addr:92:5f:ff:27:f5:ba
config: 0
state: 0
speed: 0 Mbps now, 0 Mbps max
35(tapDMZ10): addr:76:4c:a5:d8:95:64

LOCAL(br-main1): addr:64:51:06:d8:fd:bc
config: 0
state: 0
speed: 0 Mbps now, 0 Mbps max
And for this old config I only have my logs where I just see ovs-vsctl
commands, and I do not have any tunctl installed.
Also this tapDMZ11 and tapDMZ10 are not bounded to any VM.
Also, my old server has Ubuntu 14.10 and OVS 2.1.3
I'm following your recommendation, let me see what I get.

So far I search I always do find

at ip addr show where I get
"master ovs-system state DOWN"
help needed to understand why this...
By the way I'm working with fresh installs for Ubuntu 14.04 and
16.04, same issue... :(
I don't think this is an OVS issue. Have you bound something to the
tap interface to make it come up? There are some discussions on the
web if you search for "tap device down linux" if you haven't read
those yet.
