odd ... umm ... Is there even a resource pool assigned to this Organization and Workspace? The message is like there is no compatible hosts.
1. Need to ensure we have a cluster/host/RP assigned to Org and Workspace
2. Double check the physical networks, to ensure that each ESX host has it correctly bound to it
3. Ensure that the datastore where the VMs reside are available to each ESX host, and are enabled for VM provisioning.
