CPU Oversubscription

No CPU oversubscription is allowed on the host.

The amount of provisioned vCPU's should be one less than the amount of physical processor cores available in the hypervisor (ESXi host). CPU affinity is not required or recommended.

Hyper-threading can be enabled but additional logical processors made available via the hyper-threading feature do not count toward the provisioning totals.

Example:

Host machine contains 2 quad-core processors with hyper-threading enabled.

• Physical CPUs = 8

• Logical processors = 16

• Maximum vCPU’s allowed = 7 (8 – 1 available for hypervisor use)
