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.

If so any particular reason.

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.

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.
