            After installed the host, i need to attach it the networks<br>
            <br>
            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.<br>
            <br>
            I attached:<br>
            <br>
            - a screenshoot of all the network we have<br>
            <br>
            - two screenshoots for the "default" network proprierties
            (one for vnic profile, other for the proprierties)<br>
            <br>
            - supervdsm.log from host ovc2n06 (i attached all the file,
            but you will find all at the beginning)<br>
            <br>
            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.<br>
            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.<br>
            <br>
            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.<br>
            <br>
            All the hosts now are ovirt v4.1.5 and CentOS v7.3 we have
            also some old hosts on CentOS v7.2<span class="HOEnZb"><font

                    The problem is not the host-deploy, infact the
                    deploy finished without<br>
                    errors, if i remember good in the deploy process the
                    network are not set, i<br>

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