|
|
CPU quota defines the proportion based on which CPU resources to be allocated to each VM when multiple VMs compete for physical CPU resources.
|
|
|
CPU limitation defines the priority based on which CPU resources to be allocated to each VM when multiple VMs compete for physical CPU resources.
|
|
|
CPU reservation takes effect only when VMs compete for resources. If the CPU resources are sufficient, a VM can exclusively use physical CPU resources on the host if required.
|
|
|
CPU reservation defines the minimum CPU resources to be allocated to each VM when multiple VMs compete for physical CPU resources.
