You are welcome.
I'm happy you can replicate the problem.
Infact the problem is the name "default" used for the bridge any other
name works (i can't test all the names :) )

Ok
After installed the host, i need to attach it the networks
so I got the Unexpected Exception while I'm trying to add a vlan 1
(called default) to a Host, in the Setup_networks gui.
I attached:
- a screenshoot of all the network we have
- two screenshoots for the "default" network proprierties (one for
vnic profile, other for the proprierties)
- supervdsm.log from host ovc2n06 (i attached all the file, but
you will find all at the beginning)
Like already explained, it is simple to replicate the problem with
a CentOS v7.3 host, you need to create a Bridge called default
(ifcfg-default) and a Vlan 1 attached to it (ifcfg-enp12s0.1), do
a systemctl restart network and you will get the error.
To fix the problem rename the bridge to "def" for example and
change the Vlan 1 file configuration to link the new name and then
all works.
This problem is found only on the CentOS v7.3 on old CentOS v7.2
hosts the "default" bridge works, to override this problem we
changed the name to "def" for now.
All the hosts now are ovirt v4.1.5 and CentOS v7.3 we have also
some old hosts on CentOS v7.2

Could you detail them?
Also, can you share supervdsm.log from the relevant host, so
we can
understand the nature of that unexpected exception?

that is VLAN 1) it is
OK, but the host will not activate because missing the
default vlan.
If i manually add the 2 configuration files (ifcfg-default
and ifcfg-intX.1)
to the host and make a systemctl network restart, it gave
error then
ip addr reports
the vlan 1 is added, but not the Bridge to default (the
default is missing
error).
I don't know if the name "default" (for the network, VLAN
1) could be the
problem, but i can't rename now, because i need to detach
from the hosts,
but actually i can't.
I added 3 screenshoots to show you the situation, before
adding VLAN 1
("default" network), the error when adding it, and the
info on the error.
