After reading the RHEV docs I had wondered about this myself - i.e. how does one create/manage a stateful model where people always return to VMs in the same state they were left? I thought perhaps you had to detach it from the Pool for this, but haven't had time to experiment with it yet. With VMware there is a stateful pool model where the user-to-machine binding remains in effect, but the machine can be rebooted, powered off, etc. Is this what's implied by the "Manual" model?
