Before the Reservation Manager deploys virtual machines for usage, identify one or more VMware ESX servers or clusters for use. Then, define which resource pools on each VMware ESX server or cluster are targets for the virtual machine creation. To determine whether a VMware ESX server can create a virtual machine, the Reservation Manager must calculate the amount of memory available for the new virtual machines. The calculation is made on the VMware ESX servers.
If the resource pools on the VMware ESX server have defined memory limits, the Reservation Manager requires exclusive access to the resource pool. The resource pool is targeted to determine the resource availability for the future.
In the absence of memory limits at a resource pool level, the Reservation Manager calculates the amount of memory available to virtual machines. The calculation is made at the VMware ESX server level. The Reservation Manager requires exclusive use of the VMware ESX Servers to determine the accurate resource availability in the future.
Note: Resource pools and virtual machine templates are added to the vSphere Datacenter and the folder in which they are defined. You cannot use the resource pools and templates that were previously added to the Reservation Manager in the following instances:
Ensure to stabilize the vSphere structure before adding these items.
