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

I do not understand which steps you are doing until you get the
"Unexpected Exception" dialog.
Could you detail them?
Also, can you share supervdsm.log from the relevant host, so we can
understand the nature of that unexpected exception?
