Kvm artifacts are packaged into plugins/hypervisors/kvm/target/kvm-agent.zip,
scp kvm-agent.zip to kvm host, unzip, and execute run.sh, will start the kvm
agent.
Note:
Run.sh needs to be fixed, as the classpath is incorrect.
Need to modify conf/agent.properties, add guid, zone/pod/cluster,
public{private/guest}.network.device etc.
Need to create zone/pod/kvm cluster before start run.sh, otherwise, kvm
agent can't be added into mgt server.

I am thinking about running kvm agent as a http server(maybe put agent code
into a jetty server), mgt server talking to kvm agent through http instead of
tcp.
Kvm agent code will be a dummy http server, always mgt server start the talk to
agent.
You can easily using mvn jetty:run to start the agent http server.
Easy for test, you can send a command to kvm agent through wget/curl/browser
etc.
How do you think?
