The problem might be a bug.  Ask the openvswitch people.

It looks like the problem is probably:
/etc/sysconfig/network-scripts/ifup-ovs calls "systemctl start
openvswitch-nonetwork.service"
openvswitch-nonetwork.service "Wants" openvswitch.service
openvswitch.service is "After" network.target
network.target is the one that called ifup-ovs

So there's a deadlock.

At least, that's the best I can figure from looking at it briefly.


Thanks Gordon. I think the same: it is a bug (another one with systemd).

I will do what I am thinking previously: I will start openvswitches from 
libvirtd and I will see how it goes.


Thanks.

It's not a systemd bug.  If I'm correct, it's a bug in the openvswitch 
init scripts.  It's simply wrong for a component of the network startup 
to tell systemd that it needs to start after the network service is up.

If your problem is similar to the first few google hits, then some part 
of your configuration is probably calling "service something restart" or 
"systemctl restart something".  The service being restarted requires 
network.target to be available, which only happens after the interfaces 
are all up, which is a deadlock condition.


If you provide all of the configuration files you edited to enable 
openvswitch, we might be able to give you more specific advice. Your 
original question was quite vague.

Yes, my problem is very similar as described in Debian's bugtracker.
Ok, here is my openvswitches config:

DEVICE=dmzprif
DEVICETYPE=ovs
TYPE=OVSBridge
STP=off
ONBOOT=yes

DEVICE=encif
DEVICETYPE=ovs
TYPE=OVSBridge
STP=off
ONBOOT=yes

DEVICE=prodif
DEVICETYPE=ovs
TYPE=OVSBridge
STP=off
IPADDR=172.22.55.1
NETMASK=255.255.255.240
GATEWAY=172.22.55.14
ONBOOT=yes

DEVICE=vpnif
DEVICETYPE=ovs
TYPE=OVSBridge
STP=off
ONBOOT=yes

... and nics attached to some of these openvswitches:

DEVICE=eth0
OVS_BRIDGE=pubif
DEVICETYPE=ovs
TYPE=OVSPort
ONBOOT=yes

DEVICE=eth1
OVS_BRIDGE=prodif
DEVICETYPE=ovs
TYPE=OVSPort
ONBOOT=yes

Uhmm ... but I need to startup openvswitches at boot ... I only see
one option: start openvswitches when libvirtd starts ...

my suggestion was to help isolate the cause of this boot delay. if 
removing the openvswitch from your network configuration took out the 
delay, then you'd KNOW thats the problem, and you could work to further 
isolate why.   if that didn't take out the delay, then the delay is 
somewhere else.   telling me you need openvswitch isn't helping.

Ok, removed all openvswitches and it boots more fast, but message
about LSB tasks continues ...

Arrived to this point, I am pretty sure I have a problem using old nic
config ... If I disable all nics configs, voila!! ... Server boots ok.

Ok, all problems are reduced to nic settings.

The only option I see is to start openvswitches from libvirtd, but
what about ethX configs??

I think you misunderstand: systemd has a dependency management between 
services, that could make the boot faster.

Speeding up the boot was not the goal, it's an effect.

Sound like your modifications messed something with network configuration?

This looks like modifications broke network configuration and it may affect
startup speed.

Please try standard network configuration first.

just to see if thats the problem, remove openvswitches from your config, 
and if it boots fast, then you know the delay is related to that.

While booting it, if you get out of the plymouth screen (press esc), you
