Nicol=C3=A1s --------------050502090505080806060902 Content-Type: text/html; charset=3Dutf-8 Content-Transfer-Encoding: 8bit Hi,

I'm trying to set up VDSM-Fake (git://gerrit.ovirt.org/ovirt-vdsmfake.git) for some tests, however, I'm a bit confused about how does it actually work. As the instructions say, I was able to build the project with Maven (however, the org.ovirt.vdsm-jsonrpc-java dependency version had to be changed to 1.1.5 instead of 1.1.2-SNAPSHOT in pom.xml as this latter is no longer provided at the repository).

Once built, I run mvn jetty:run and the server started correctly:

2016-02-02 11:01:51.957:INFO::jetty-6.1.26
2016-02-02 11:01:52.804:INFO::No Transaction manager found - if your webapp requires one, please configure one.
2016-02-02 11:01:53,424 Application initialized.
2016-02-02 11:01:53,442 Opening a Stomp server localhost:54322
2016-02-02 11:01:53.702:INFO::Started SelectChannelConnector(a)0.0.0.0:54321
[INFO] Started Jetty Server
[INFO] Starting scanner at interval of 10 seconds.

I could indeed verify it's listening on the VDSM port:

[root(a)host ovirt-vdsmfake]# netstat -atpn | grep 54321
tcp6=C2=A0=C2=A0=C2=A0=C2=A0=C2=A0=C2=A0 0=C2=A0=C2=A0=C2=A0=C2=A0=C2= =A0 0 :::54321=C2=A0=C2=A0=C2=A0=C2=A0=C2=A0=C2=A0=C2=A0=C2=A0=C2=A0=C2=A0= =C2=A0=C2=A0=C2=A0=C2=A0=C2=A0 :::*=C2=A0=C2=A0=C2=A0=C2=A0=C2=A0=C2=A0=C2=A0=C2=A0=C2=A0=C2=A0=C2= =A0=C2=A0=C2=A0=C2=A0=C2=A0=C2=A0=C2=A0=C2=A0=C2=A0 LISTEN=C2=A0=C2=A0=C2= =A0=C2=A0=C2=A0 44870/java

So the next step is to add a fake host via REST. I used scripts provided here and I successfully added the host, however, it starts installing all the VDSM packages as it were a normal host and therefore it tries to start vdsmd as well, which throws an error as the Jetty Server is already listening on the 54321 port. I shut down the Jetty Server and allowed oVirt Manager to install all the packages properly, then stopped vdsmd and started the Jetty Server, but expectedly oVirt Engine fails with message "Host xxx is non responsive", so what I actually got is a real VDSM host and not a fake one.

FWIW, the fake VDSM runs on a different host, ports are reacheable from the oVirt engine, proper /etc/hosts has been added to the engine to reach the host, and no further customization of web.xml has been done.

I feel like I'm missing something here. Could someone shed some light on what's wrong?

Thanks.
