properties.

Configuring Resource Allocation Settings
When available resource capacity does not meet the demands of the resource consumers (and virtualization
overhead), administrators might need to customize the amount of resources that are allocated to virtual
machines or to the resource pools in which they reside.
Use the resource allocation settings (shares, reservation, and limit) to determine the amount of CPU,
memory, and storage resources provided for a virtual machine. In particular, administrators have several
options for allocating resources.
n
Reserve the physical resources of the host or cluster.
n
Set an upper bound on the resources that can be allocated to a virtual machine.
n
Guarantee that a particular virtual machine is always allocated a higher percentage of the physical
resources than other virtual machines.
