Description of problem:
[Hosted-engine --deploy] > Can't configure management bridge over Vlan, default gateway is removed during deployment.
While running hosted-engine deployment, host loosing connectivity and deployment script is broken. Stucked in this stage: [ INFO  ] Configuring the management bridge....
For some reason in this stage the default gateway is removed. 

Version-Release number of selected component (if applicable):

How reproducible:

Steps to Reproduce:
1. yum install ovirt-hosted-engine-setup
2. hosted-engine --deploy
3. configure management bridge(rhevm) over Vlan tagged interface 

Actual results:
Deployment script is broken and host lost connectivity, because default gateway was removed

Expected results:
hosted-engine --deploy should work. Should be able to configure mgmt bridge over Vlan tagged interface

Additional info:

Comment 2 Michael Burman 2014-09-29 07:21:49 UTC
I haven't mentioned that i'm using static IP configured over Vlan.

Comment 3 Sandro Bonazzola 2014-09-29 14:06:46 UTC
Antoni, Dan, is something changed recently in VDSM that may lead to this or ahve you already seen something like this out of hosted engine?
The code handling that part is not changed on setup side.

In vdsm I see:

After that it tries to connect to the storage over NFS and fails (due to missing gateway probably)

Comment 5 Antoni Segura Puimedon 2014-09-29 14:31:42 UTC
Thanks for the paste, Sandro, if fails to get the GATEWAY into the setupNetworks command. It is most likely a bug in my code in the hosted engine deploy plugin (regrettably, I only tested it with dhcp).

Comment 6 Sandro Bonazzola 2014-09-29 15:42:30 UTC
Tanks Antoni, will look into that.

Comment 7 Sandro Bonazzola 2014-10-01 06:34:22 UTC
I think it may be something related to the case of the configuration key:

    if 'BOOTPROTO' in port_info['cfg']:
        attrs['bootproto'] = port_info['cfg']['BOOTPROTO']
    if attrs.get('bootproto') == 'dhcp':
        attrs['blockingdhcp'] = True
        attrs['ipaddr'] = port_info['addr']
        attrs['netmask'] = port_info['netmask']
        gateway = port_info.get('gateway')
        if gateway is not None:
            attrs['gateway'] = gateway

looks like we had something similar with BOOTPROTO in the past, trying to verify.

Comment 9 Michael Burman 2014-10-13 07:28:08 UTC
Verified on - 3.5.0-0.14.beta.el6ev and ovirt-hosted-engine-setup-1.2.1-1.el6ev.noarch
