I will add another hypervisor host. Is there any network requirement
for the management server and hypervisor host?
May I know how does the management server know the hypervisor host
and include it to its management?
That's what CloudStack is for. It 'discovers' the hypervisor through
its discoverers - XenDisoverer talks to XAPI to manage Xenservers,
KVM
talks via SSH/libvirt and VmWare talks through the vmware SDK. It's
all abstracted so you don't have to understand the mechanics of
what's
going on underneath.
Your hypervisor host needs to be prepared with the
OS+hypervisor-software of your choice. It will need to have one NIC
that the management server (your laptop) can reach. You will need
some
storage (NFS) where you can pre-seed the systemVM template which is
used to launch service VMs that cloudstack uses for management
purposes.
Thanks for the detailed explanation!
All this and more is in the installation guide - let us know if
there's anything missing and you haven't been able to figure out
about
the installation.

I create a file named db.properties.override under utils/conf. Put
my root password inside it and it works!
Cool! Do you mind updating the wiki @
https://cwiki.apache.org/confluence/display/CLOUDSTACK/How+to+build+on+master+branch
I updated the wiki :)
The command "mvn -pl :cloud-client-ui jetty:run" gives me a
error:[INFO] Couldn't find specified project dir:
/home/meng/cloudstack/:cloud-client-ui
I notice that there is no cloud-client-ui directory under
cloudstack. So I switched to "mvn -pl client jetty:run", however it
told me the maven-jetty-plugin does not exist.
Yes, client will work.

Any light on this?
Odd, the jetty plugin should be downloaded automatically from
repo.maven.org. If your mvn clean install step worked I'm guessing
you're not behind any sort of http_proxy?
The problem turns out to be that I am using maven2 to build the
project. After I switch to maven3 the problem is gone.
The management server runs at local port 8080 which is also the default
port for tomcat. As the deployment environment requires installing
tomcat. Users follow this devcloud wiki usually have tomcat service
running before they start the management server. In order to run the
management server users can either shut down tomcat service or switch to
another port.
I added this to the wiki also.
