VMs which do not belong to a VM group are assigned to a CPU pool when the VM is initialized, see "Initializing a VM". After initialization, the VM2000 administrator can assign a VM which is not assigned to a VM group to another CPU pool during ongoing operation using /ASSIGN-VM-TO-CPU-POOL, see the section "Assigning a VM or VM group to a (different) CPU pool".
/CREATE- or /MODIFY-VM-DEFINITION can be used in a VM definition to enter the affiliation of a VM to a CPU pool in a VM definition. Detailed information can be found in the section "Working with VM definitions".On SU /390, the VM2000 administrator assigns VM groups to a CPU pool when the VM group is initialized using /CREATE-VM-GROUP (CPU-POOL operand), see "Creating a VM group". After initialization, the VM2000 administrator can assign the VM group (with all member VMs) to another CPU pool during ongoing operation using /ASSIGN-VM-GROUP-TO-CPU-POOL, see the section "Assigning a VM or VM group to a (different) CPU pool".
