4.
Type a resource pool name in the Name text box, in this case
WebServers
.
5.
Coni gure the resource allocations, if desired, to establish limits and reservations for the
resource pool.
The limit establishes a hard cap on the resource usage, while the reservations establish a
resource guarantee.

Click OK.
So now that you've created the WebServers resource pool, you can place VMs into it, as
shown in Figure 8.10. Putting VMs into a resource pool is simply a matter of creating new VMs
in it (refer to Chapter 9, “Creating and Managing Virtual Machines”) or dragging and dropping
existing VMs into it.
Figure 8.10
As objects in the
inventory, resource
pools are potential
levels of infrastruc-
ture management.
Additionally, resource pools become inventory objects to which you can assign permissions.
The same process you followed earlier, described in the section “Granting Permissions,” applies
here as well. Simply assign permission to the resource pool, and ensure that the Propagate To
Child Objects check box is selected. Those permissions will also apply to all the VMs in the
resource pool.
Using resource pools helps you accomplish a couple of key goals: better organization for your
VMs and better control over permissions assigned to those VMs.
However, having said all of this, we must point out that we generally
do
not
recommend
using
resource
pools
in
this
way
. Although you can certainly use resource pools to organize VMs and
assign permissions, resource pools are intended to help control resource allocation and con-
sumption; they are not intended as a means of organizing VMs. In Chapter 11, we'll discuss
resource allocation and why using resource pools solely for VM organization is generally not
a good idea; we highly recommend reading that chapter and gaining a i rm understanding of
how resource pools affect resource allocation.
Now that we've shown you how to assign permissions, we need to show you how to remove
permissions. Let's look at that next.
Removing Permissions
When your management needs change or if you've made some improper permissions assign-
ments, you can remove permissions. In the section “Granting Permissions,” you walked through
