I have 4 esxi 5.5 hosts and now i just installed the vcenter server .i am trying to manage the all the hosts cluster enviorment because two of the hosts have lot of RAM free and less of Datastore storage space and the remaining two have lot of Datastore storage space and less of RAM.
so now i want to share the resources in vcenter for these hosts.
i have created one Data center then i created a cluster with vmotion option enabled.
when i try to add the host in to this cluster it gives an option "Put all of the host virtual machine in the cluster resource pool .resource pool currently present on the host will be deleted.
i am afraid that it will not delete all of my vms on this host,
please guide me in detail
