Moftah, Do NOT try to add this pool to CloudStack, you could lose all your existing VMs.
What you need to do is setup a new pool (CloudStack Cluster) then import each VM into CloudStack.

We are using NFS for all storage and we match all requirements in term of networking for cloudstack installation. my question is it safe to install cloudstack on the existing pool ? or that will affect the existing VMs and or hosts ? I am ok with migrating all existing VMs to cloudstack or even not migrating them. my only concern is that If cloudstack can co exist with VMs thats are existing in the system and if not if there an easy way to make existing VMs managed by cloudstack thanks Need Enterprise Grade Support for Apache CloudStack?
