blocks|key|6390242|text|也许有点晚了，但在我的例子中，问题是两个接口的UUID字段是相同的，而且它们必须是唯一的。禁用NetworkManager是可行的，但真正的解决方案是更改/删除字段。把这个留在这里供将来参考。|type|unstyled|depth|inlineStyleRanges|entityRanges|data|entityMap^0^^$0|@$1|2|3|4|5|6|7|C|8|@]|9|@]|A|$]]]|B|$]]

Maybe a little late, but the problem in my case was that the UUID field of the two interfaces was the same, and they must be unique. Disabling NetworkManager does the trick, but the real solution would be changing/deleting the field. Leaving this here for future reference.

I was facing the same issue. Fortunately,

<pre><code>/etc/rc.d/init.d/network stop

gracefully stopped the network service.
Then I did an:

<pre><code>ip addr flush dev &lt;&lt;dev-name&gt;&gt;
</code></pre>

After that you can start the service, using either <code>systemctl</code> or <code>/etc/rc.d/init.d/network start</code>.

I had this error after importing a VM.
The solution is to fix the HW address in the /etc/sysconfig/network-scripts/ifcfg-ens32 (ens32 happened to be my interface. You can check yours using Network Manager with nmtui)file.

Type 'ip addr' and note down the HW addr of your interface, for example 00:50:56:8d:6a:9e.Look up for the interface you are interested in from the list you get from 'ip addr'.

Open to edit your /etc/sysconfig/network-scripts/ifcfg-ens32 (change ifcfg-ens32 with your interface name, as said above get it from nmtui) and modify that address next to the key HWADDR.

Now: service network restart

Just stop and disable NetworkManager

And once again restart services it will be work

<pre><code>#systemctl stop NetworkManager
#systemctl disable NetworkManager

#service network restart
</code></pre>

The switch configured on the server (Centos 7) is configured as trunk for VLAN#115,2014.
I have loaded 

<pre><code># lsmod | grep 8021q
# modprobe 8021q
</code></pre>

I would like to configure an IP address on the server using the VLAN#115
Performing the following configuration:

ifcfg-em1

<pre><code>TYPE=Ethernet
BOOTPROTO=none
DEFROUTE=yes
PEERDNS=yes
PEERROUTES=yes

</code></pre>

ifcfg-em1.115

<pre><code>TYPE=Ethernet

DEVICE=em1.115
VLAN=yes
ONBOOT=yes
</code></pre>

I ended up being not able to restart the network service.
The error message appearing is : 

<pre><code>Failed to start LSB: Bring up/down networking.
</code></pre>

What am doing wrong ?
