Reconfigure activity The Reconfigure activity updates the number of CPUs and the amount of memory assigned to a virtual machine. These variables determine the behavior of the activity. Table 1. Input variables Field Description vCenter IP address of the vCenter server that manages the virtual machine to operate. VM uuid The VMware universal unique identifier assigned to this virtual machine. If you are creating your own workflow, see Virtual Machine UUID for instructions on properly formatting the unique identifier. Number of CPUs The number of CPUs to allocate to the virtual machine. If this field is blank, you must reconfigure the memory for this virtual machine. Memory (MB) The amount of memory, in megabytes, to allocate to the virtual machine. If this field is blank, you must reconfigure the number of CPUs for this virtual machine. This value must be divisible by 4. If the amount is not divisible by 4, the activity succeeds but the virtual machine cannot start.
