How many system memory does ESX Server 3.0 use for the VMkernel?
Memory used by the ESX Server system. ESX Server 3.0 uses at least _____ of system memory for the VMkernel, plus additional memory for device drivers. This memory is allocated automatically when the ESX Server is loaded and is not configurable.
Which is this process called?
When you power on a virtual machine, the system checks the amount of CPU and memory resources that have not yet been reserved. Based on the available unreserved resources, the system determines whether it can guarantee the reservation for which the virtual machine has been configured (if any). This process is called _______________.
