spec update_spec Specification for updating the CPU-related settings of the virtual machine.
spec.count long New number of CPU cores. The number of CPU cores in the virtual machine must be a multiple of the number of cores per socket.

The supported range of CPU counts is constrained by the configured guest operating system and virtual hardware version of the virtual machine.

If the virtual machine is running, the number of CPU cores may only be increased if vcenter.vm.hardware.cpu.info.hot_add_enabled is true, and may only be decreased if vcenter.vm.hardware.cpu.info.hot_remove_enabled is true.

Optional. If unset, the value is unchanged.

spec.cores_per_socket long New number of CPU cores per socket. The number of CPU cores in the virtual machine must be a multiple of the number of cores per socket.

Optional. If unset, the value is unchanged.

spec.hot_add_enabled boolean Flag indicating whether adding CPUs while the virtual machine is running is enabled.

This field may only be modified if the virtual machine is powered off.

Optional. If unset, the value is unchanged.

spec.hot_remove_enabled boolean Flag indicating whether removing CPUs while the virtual machine is running is enabled.

This field may only be modified if the virtual machine is powered off.

Optional. If unset, the value is unchanged.
