Re: [ovirt-users] Questions regarding neutron implementation for oVirt 3.5

11 Dec 2014

      That did the trick guys. Thanks so much to both of you for all of your help. I may return with some additional questions regarding placing neutron/keystone/rabbit on a separate blade using devstack or something to quickly implement. If you have any comments please don't hesitate to let me know if you think that I would be going down a bad path or such.

Again, thanks for everything.

Regards,
Andrew Brimer

Hi Modi,
In the discussion found at
https://bugzilla.redhat.com/show_bug.cgi?id=1064231 Comment #12 
states that the fedora Jackson package will not make a difference 
because the Jackson jar files pre-packaged in JBoss is what is 
actually used for this. Is that a true statement in your opinion? 
If so, how can I locate the appropriate jar and then what is the 
path in the oVirt Engine that I need to place that/those jar 
file(s) into?
Adding Juan to verify the suggested sequence, and to verify no 
better alternative is available.
In order to upgrade the jackson module version, you should replace 
both the .jar files and edit each module.xml of the corresponding 
jar file:
The files which should be replaced could be identified by:
$ find /usr/share/jboss-as-7.1.1.Final/modules -name "jackson*.jar"
/usr/share/jboss-as-7.1.1.Final/modules/org/codehaus/jackson/jackson
-jaxrs/main/jackson-jaxrs-1.9.2.jar
/usr/share/jboss-as-7.1.1.Final/modules/org/codehaus/jackson/jackson
-mapper-asl/main/jackson-mapper-asl-1.9.2.jar
/usr/share/jboss-as-7.1.1.Final/modules/org/codehaus/jackson/jackson
-xc/main/jackson-xc-1.9.2.jar 
/usr/share/jboss-as-7.1.1.Final/modules/org/codehaus/jackson/jackson
-core-asl/main/jackson-core-asl-1.9.2.jar
Jar files can be downloaded from maven repository:
http://central.maven.org/maven2/org/codehaus/jackson/jackson-jaxrs/1
.9.9/jackson-jaxrs-1.9.9.jar 
http://central.maven.org/maven2/org/codehaus/jackson/jackson-xc/1.9.
9/jackson-xc-1.9.9.jar 
http://central.maven.org/maven2/org/codehaus/jackson/jackson-mapper-
asl/1.9.9/jackson-mapper-asl-1.9.9.jar
http://central.maven.org/maven2/org/codehaus/jackson/jackson-core-as
l/1.9.9/jackson-core-asl-1.9.9.jar
After the replacement, you should have the following:
/usr/share/jboss-as-7.1.1.Final/modules/org/codehaus/jackson/jackson
-jaxrs/main/jackson-jaxrs-1.9.9.jar
/usr/share/jboss-as-7.1.1.Final/modules/org/codehaus/jackson/jackson
-mapper-asl/main/jackson-mapper-asl-1.9.9.jar
/usr/share/jboss-as-7.1.1.Final/modules/org/codehaus/jackson/jackson
-xc/main/jackson-xc-1.9.9.jar 
/usr/share/jboss-as-7.1.1.Final/modules/org/codehaus/jackson/jackson
-core-asl/main/jackson-core-asl-1.9.9.jar
Next, update the "module.xml" version from 1.9.2 to 1.9.9 files 
detected
by:
$ find  
/usr/share/jboss-as-7.1.1.Final/modules/org/codehaus/jackson/ -name "module.xml"
/usr/share/jboss-as-7.1.1.Final/modules/org/codehaus/jackson/jackson-jaxrs/main/module.xml:
<resource-root path="jackson-jaxrs-1.9.2.jar"/>
/usr/share/jboss-as-7.1.1.Final/modules/org/codehaus/jackson/jackson-mapper-asl/main/module.xml:
<resource-root path="jackson-mapper-asl-1.9.2.jar"/>
/usr/share/jboss-as-7.1.1.Final/modules/org/codehaus/jackson/jackson-xc/main/module.xml:
<resource-root path="jackson-xc-1.9.2.jar"/>
/usr/share/jboss-as-7.1.1.Final/modules/org/codehaus/jackson/jackson-core-asl/main/module.xml:
<resource-root path="jackson-core-asl-1.9.2.jar"/>
for example, by editing them in place by:
$ find  
/usr/share/jboss-as-7.1.1.Final/modules/org/codehaus/jackson/ -name 
"module.xml" -exec sed 's/1.9.9/1.9.2/' {} \;
And verify the output is:
$ find  
/usr/share/jboss-as-7.1.1.Final/modules/org/codehaus/jackson/ -name 
"module.xml" | xargs grep 1\.9
/usr/share/jboss-as-7.1.1.Final/modules/org/codehaus/jackson/jackson-jaxrs/main/module.xml:
<resource-root path="jackson-jaxrs-1.9.9.jar"/>
/usr/share/jboss-as-7.1.1.Final/modules/org/codehaus/jackson/jackson-mapper-asl/main/module.xml:
<resource-root path="jackson-mapper-asl-1.9.9.jar"/>
/usr/share/jboss-as-7.1.1.Final/modules/org/codehaus/jackson/jackson-xc/main/module.xml:
<resource-root path="jackson-xc-1.9.9.jar"/>
/usr/share/jboss-as-7.1.1.Final/modules/org/codehaus/jackson/jackson-core-asl/main/module.xml:
<resource-root path="jackson-core-asl-1.9.9.jar"/>
Last thing is either rename the .jar.index file names to match the 
new version or remove them, so jboss will auto-generate them.
$ find  
/usr/share/jboss-as-7.1.1.Final/modules/org/codehaus/jackson/ -name ".jar.index"
If you are using Fedora 20 then you are also using the 
"ovirt-engine-jboss-as" package. That is a repackaging of JBoss AS 
7.1.1 needed because Fedora 20 ships with WildFly, and we don't support it.
What is relevant for you is that the location of the files is not 
/usr/share/jboss-as-7.1.1.Final but /usr/share/ovirt-engine-jboss-as.
Other than that the instructions provided by Moti are correct. However 
the modifications of those files will be lost when the 
"ovirt-engine-jboss-as" package is updated (unlikely). I'd suggest to 
create a new module from scratch, in the 
/usr/share/ovirt-engine/modules/common directory. I did so and it is 
available here:
https://jhernand.fedorapeople.org/jackson-1.9.9-module.zip
And you can install it as follows:
# curl -o jackson-1.9.9-module.zip
https://jhernand.fedorapeople.org/jackson-1.9.9-module.zip
  # unzip -o -d /usr/share/ovirt-engine/modules/common
jackson-1.9.9-module.zip
Then restart the engine:
# systemctl restart ovirt-engine
The right solution is to do exactly this during the build of the engine:
core: Use Jackson 1.9.9

Thanks!

Am I on the right track? What is your advice?
Kind Regards,

Hi Moti,
Yes. I did not consider sending this out in a way that everyone 
would benefit, sorry. This is the first time that I have posted a 
question for oVirt and just saw your email address in the 
instructions document and quickly fired off an email. I will post 
to users@ovirt.org for all future questions, I would love to 
participate in any way possible to help you guys (and those of us 
who rely on your efforts) move things forward. If you would like 
for me to forward the next (or this one) message to users@ovirt.org I would be very happy to.
Done. I think this will help other users which might face the same 
problem.
...
To answer your question regarding testing connectivity, yes I 
pressed the test button and was provided the success message. In 
addition to that, when I create a net and subnet in oVirt I am 
able to query neutron and find them.
I can also create a net in neutron (neutron net-create) and import 
it into oVirt. It seems that the two systems are communicating but 
that somewhere along the way an error is halting your workflow 
(see the snippit from the
/var/log/ovirt-engine/engine.log)
The cause for the error is documented in bug 1064231 [1] as a 
result of a buggy jackson package version which is delivered by 
jboss. The bug wasn't fixed for f20, and it appears since ovirt-engine-3.4.
Although requests are being sent to the neutron server and being 
processed successfully, retrieving the subnets from neutron fails 
due to the bug in jackson.
Local upgrade of the jackson package under jboss-as-7.1 to 1.9.9 or 
using
jboss-eap-6.3 which is shipped with jackson-1.9.9 will solve this issue.

Hi Andrew,
Generally, it is preferable to send ovirt related questions to 
users@ovirt.org for the benefit of other community members.
If no concerns, please include it in your next reply's cc.

Subject: Questions regarding neutron implementation for oVirt 3.5
Good Morning Moti,
I am hoping that you may be able to help me out if you have a 
little time Sir.
I have followed your instructions (youtube and 
NeutronVirtualAppliance
document) for integrating Neutron into my oVirt 3.5 system and I 
am running into some issues when attempting to create a subnet.
Were you able to verify connectivity to the neutron appliance 
after it was added to the ovirt-engine as shown on 
https://www.youtube.com/watch?feature=player_detailpage&v=naLFSFwHI94#t=510?
Could you post the /var/log/ovirt-engine/engine.log ?
Thanks,
Moti
...
Networks->extent->Subnets->New
Network: extent
Name: extsubtest
CIDR:10.0.9.0/24
[OK]
Returns: Error while executing action Add Subnet to Provider: 
Failed to communicate with the external provider.
On the Neutron machine:
neutron net-list shows 'extnet'
neutron subnet-list shows 'extsubtest'
neutron router-list shows nothing
oVirt Visor 1 is the host that I used when following your 
instructions and Visor 2 is the additional host added per your 
instructions towards the end of the video.
I really appreciate any help that you can provide, I only have 
Neutron integration to complete and will then have a fully 
working oVirt 3.5 stack running.
Kind Regards,
