It is most probably feasible to add a cluster managed by Cloudstack but not 
recommended or supported. Certainly I would not add an existing cluster as that 
could be asking for trouble. From my experience, it has issues with performance 
as Cloudstack talks via https to the vc api and is quite chatty and you may get 
undesired results, for example, Cloudstack not being able to manage VMs in 
virtual center correctly and even possible loss of data. We tried this in the 
early days of VMware integration with Cloudstack and the environment just did 
not work as expected. Tasks in VC just failed or never executed correctly.

Hi Oliver

        From you answer can I take its feasible to add current vCenter into 
CloudStack but its not recommended. If so any particular reason.

Thanks and Regards

I would set up a new virtual center and add this to Cloudstack and then one by 
one export and import your VMs in to Cloudstack one by one. I would definitely 
recommend not updating the database or importing your existing virtual center 
in to cloudstack. The export format will need to be OVA. You should not use the 
same virtual center that you manage with Cloudstack.
Importing them this way means Cloudstack will track the life cycle of the VMs 
however the downside would be you will have a template for each VM you import 
which will inevitably take up space on your secondary NFS server and the ESX 
datastore. Depending on your size of VMs, depends on how long this will take 
and you might have to tweak some global settings if the OVA templates sizes are 
large.

It would be good if you could import them straight in  but I do not think this 
is possible. 


Here is an extract from the installation guide.

6.4.2. Add Cluster: vSphere

Host management for vSphere is done through a combination of vCenter and the 
CloudStack admin UI. CloudStack requires that all hosts be in a CloudStack 
cluster, but the cluster may consist of a single host. As an administrator you 
must decide if you would like to use clusters of one host or of multiple hosts. 
Clusters of multiple hosts allow for features like live migration.
Clusters also require shared storage such as NFS or iSCSI.
For vSphere servers, we recommend creating the cluster of hosts in vCenter and 
then adding the entire cluster to CloudStack. Follow these requirements:

    Do not put more than 8 hosts in a vSphere cluster
    Make sure the hypervisor hosts do not have any VMs already running before 
you add them to CloudStack.

Hi 

        In our office we are having VMWare EsXi two Servers with multiple VM's 
managed by VCenter. Can we manage Virtual Machines CloudStack by installing it 
in one of the Virtual Machines.

Thanks  in Advance

Best Regards

Instances yes. Overall cloud, that will take some time and energy, and a lot of 
hacking, there was a proposal sometime back to import existing hosts and 
instances to CloudStack which was never implemented, maybe in future.

Longer way: For each instances, export ova, deploy/start CloudStack, upload ova 
and start instances in CloudStack.

HTH.
