As for memory configuration, shares, reservation, and limit parameters can also be configured for the CPU:

• Shares: This parameter allows you to prioritize access to resources during resource contention. Similar to memory shares, it determines how much CPU will be provided to a VM in case of contention with other VMs.
• Reservation: Used to specify the minimum CPU cycles guaranteed for a VM and you can't reserve more CPU cycles than the ESXi is capable of delivering. The host must have enough physical CPU capacity to satisfy the reservation, otherwise the VM won't be able to power on.
• Limit: Used to prevent a VM accessing additional CPU cycles even if they are available to be used. The VM won't use more CPU cycles than specified in the limit.

To configure shares, reservation, and limit CPU parameters, follow these steps:

1. Right-click the VM to configure and select Edit Settings
2. Access the Virtual Hardware tab and expand the CPU item
3. Configure the parameters you need, then click OK to confirm:

To improve resource management, CPU configuration can be enhanced by enabling additional components and parameters:

• Multicore processors: All modern servers are equipped with multicore processors, that is, processors that combine two or more processor cores into a single circuit, referred to as a socket. This solution enables the improvement of performance, providing benefits for hosts that provide multitasking of VMs.
• Hyperthreading: This is a technology that allows a single physical processor core to behave like two logical processors. With this technology, a single processor core is able to execute two independent threads simultaneously, improving performance.
• CPU affinity: This is a configuration that assigns a specific VM to a specific physical CPU core and can be used for compliancy to license requirements. CPU affinity should be used carefully because it can introduce potential issues, such as interfering with the ESXi host's ability to meet the reservation and shares specified for a VM.
