Hello,
I'm trying to run kvm agent on development environment by maven. But,
the trial has stuck. I think that there is a problem through which
dependence circulates (agent & cloud-plugin-hypervisor-kvm).
The following is an outline of my trial.
1. execute maven
(mvn exec:java -pl agent
-Dexec.mainClass=com.cloud.agent.AgentShell -Dnonoss)
-> an exception is raised
com.cloud.utils.exception.CloudRuntimeException: Unable to find
com.cloud.configuration.DefaultInterceptorLibrary
2. add dependency (cloud-server) to pom.xml of agent and re-execute maven
-> an exception is raised
Caused by: com.cloud.utils.exception.CloudRuntimeException: Unable to
find the implementation version of this agent
at com.cloud.agent.AgentShell.init(AgentShell.java:382)
at com.cloud.agent.AgentShell.main(AgentShell.java:630)
... 6 more
Hmm, that seems something that goes wrong when the Agent is not ran by JSVC.
A couple of weeks ago the AgentShell was changed to run with JSVC:
https://git-wip-us.apache.org/repos/asf?p=incubator-cloudstack.git;a=commitdiff;h=eab3e4783e0f8aba7dab889bdfcc441a028b387a
I'll take a look at this and try to reproduce it locally.

Is using JSVC recommended even if on development environment? I would
like to know the development approach recommended for Agent.
No, it should also run without JSVC with just "plain" Java. I'll check
this asap.

3. skip version check and re-execute maven
-> permission error
Unable to start agent: Unable to create the /var/run/agent.pid. Are
you running as root?
4. run as root
-> an exception is raised

5. add dependency (cloud-plugin-hypervisor-kvm) to pom.xml of agent
and re-execute maven
-> maven error

Even if it remove dependency of agent from
cloud-plugin-hypervisor-kvm, it does not run.
It was not found although I looked for the document written about the
method of running kvm agent. Or is the method known if it is not maven
but ant?
The patch used for this trial is attached.
Thanks,
Satoshi
