Each virtual machine consumes a portion of the CPU, memory, network bandwidth, and storage resources of the ESX Server host. The host guarantees each virtual machine Its share of the underlying hardware resources based on a number of factors:

A.
Available resources for the virtual machine

B.
Available resources for the ESX Server host (or the cluster).

C.
Reservation, limit, or shares of the ESX Server host

D.
Reservation, limit, or shares of the virtual machine

E.
Number of virtual machines powered on, and resource utilization by those virtual machines.

F.
Amount of memory

G.
Overhead required to manage the virtualization.

H.
Reservation, limit, and shares the administrator assigned to the resource pools in the resource pool hierarchy.

Explanation:

Each virtual machine consumes a portion of the CPU, memory, network bandwidth, and storage resources of the ESX Server host. The host guarantees each virtual machine Its share of the underlying hardware resources based on a number of factors:
– Available resources for the ESX Server host (or the cluster).
– Reservation, limit, or shares of the virtual machine. These attributes of a virtual machine have default values that you can change to customize resource allocation.
– Number of virtual machines powered on, and resource utilization by those virtual machines.
– Reservation, limit, and shares the administrator assigned to the resource pools in the resource pool hierarchy.
– Overhead required to manage the virtualization.
