Bug 991087

I really hope the Ofer understands what this bug is all about, since I do not. To track this properly, please report the versions of the relevant packages (including vdsm), the content of the relevant ifcfg files before and after installation, and relevant logs.

I tried reproducing that on a clean machine 
using ovirt-engine-3.3.0-0.2.master.20130813190148.git4d3992c.fc19.noarch
and now the bridge is not being created at all and the all in one plugin does not seem to be running

it's a clean f19 machine

Did not manage to reproduce.

Started from a clean f19 VM.
Before setup, I had:
[root@ovirte1 network-scripts]# cat ifcfg-eth0 
HWADDR=52:54:00:1C:7B:48
TYPE=Ethernet
BOOTPROTO=dhcp
DEFROUTE=yes
PEERDNS=yes
PEERROUTES=yes
IPV4_FAILURE_FATAL=no
IPV6INIT=yes
IPV6_AUTOCONF=yes
IPV6_DEFROUTE=yes
IPV6_PEERDNS=yes
IPV6_PEERROUTES=yes
IPV6_FAILURE_FATAL=no
NAME=eth0
UUID=d41795c2-637e-4f48-b348-122317a98883
ONBOOT=yes

After setup with allinone, I had:
[root@ovirte1 network-scripts]# cat ifcfg-eth0
# Generated by VDSM version 4.12.0-78.git8f7eebf.fc19
DEVICE=eth0
ONBOOT=yes
HWADDR=52:54:00:1c:7b:48
BRIDGE=ovirtmgmt
MTU=1500
NM_CONTROLLED=no
STP=no
[root@ovirte1 network-scripts]# cat ifcfg-ovirtmgmt
# Generated by VDSM version 4.12.0-78.git8f7eebf.fc19
DEVICE=ovirtmgmt
ONBOOT=yes
TYPE=Bridge
DELAY=0
BOOTPROTO=dhcp
DEFROUTE=yes
NM_CONTROLLED=no
STP=no

Naturally, network configuration changes might temporarily disconnect the network, but this didn't happen for me this time.
We still might want to add a recommendation to run under 'screen' just in case, as we do in hosted-engine: http://gerrit.ovirt.org/17258

Versions:
ovirt-engine-3.4.0-0.2.master.20130822162248.gite4782ef.fc19.noarch
vdsm-4.12.0-78.git8f7eebf.fc19.x86_64

Did the all in one installation finished for you succeessfully with host in "up" state?
this is odd.

meaning it did manage to connect to the engine and do some stuff, but failed
during 'Adding the local host to the local cluster'. This can be a failure of the engine, host-deploy or vdsm. If you still have this machine, please attach all of the relevant logs including host-deploy/vdsm/engine.log. If you don't, please try to reproduce using current versions.

Also, perhaps it was fixed by: http://gerrit.ovirt.org/18262

No, it's not related to http://gerrit.ovirt.org/18262 .

Your log shows that you first had:

2013-08-14 11:05:37 INFO otopi.plugins.ovirt_engine_setup.core.misc misc._closeup:85 Starting engine service

and then:

2013-08-14 11:05:37 INFO otopi.plugins.ovirt_engine_common.system.apache apache._closeup:76 Restarting httpd

and only later 503.

Verified again, just to make sure.

ran cleanup, removed some packages, restored ifcfg-* from backup, rebooted.
Had:
========================================================================
[root@ovirte1 ~]# nm-tool 

NetworkManager Tool

State: connected (global)

- Device: eth0  [eth0] ---------------------------------------------------------
  Type:              Wired

    DNS:             192.168.122.1
========================================================================
Then installed again packages, ran engine-setup which finished successfully, then had:

  Driver:            bonding

========================================================================
So eth0 did change from "connected" to "unmanaged" by NM.

Ohad, seems like this issue has been resolved already.
Please re-open if it happens again.
