  • There are also VMkernel management worlds performing management tasks on behalf of the ESXi host. For example, there are a number of worlds handling the communication with a management server. A few worlds execute periodic tasks for the resource management algorithm. However, the CPU demand of the VMkernel management worlds is not significant and most of the CPU resources are available for virtual machines. Be aware that the CPU overhead is not zero.
    Other than worlds, there are interrupts and I/O contexts that need to be scheduled. Once an interrupt is serviced, the related I/O task may be deferred to an I/O context which can be processed separately. An I/O context is scheduled after an interrupt is serviced, a VMkernel system call is made, or a world switch happens. The VMkernel takes every opportunity to ensure I/O contexts are scheduled with minimum delay.

    na B essa não é afunção da VMKernel.

    Me corrijam se eu estiver errado.
