When you create a virtual machine, the New Virtual Machine wizard allows you to specify a resource pool location as part of the creation process. You can also add an existing virtual machine to a resource pool.
About this task
When you move a virtual machine to a new resource pool:
The virtual machine’s reservation and limit do not change.
If the virtual machine’s shares are high, medium, or low, %Shares adjusts to reflect the total number of shares in use in the new resource pool.
If the virtual machine has custom shares assigned, the share value is maintained.Note:
Because share allocations are relative to a resource pool, you might have to manually change a virtual machine’s shares when you move it into a resource pool so that the virtual machine’s shares are consistent with the relative values in the new resource pool. A warning appears if a virtual machine would receive a very large (or very small) percentage of total shares.
The information displayed in the Resource Allocation tab about the resource pool’s reserved and unreserved CPU and memory resources changes to reflect the reservations associated with the virtual machine (if any).Note:
If a virtual machine has been powered off or suspended, it can be moved but overall available resources (such as reserved and unreserved CPU and memory) for the resource pool are not affected.
Launch the vSphere Client and log in to a vCenter Server system.
- In the vSphere Client, select the virtual machine in the inventory.
The virtual machine can be associated with a standalone host, a cluster, or a different resource pool.
- Drag the virtual machine (or machines) to the resource pool.
If a virtual machine is powered on, and the destination resource pool does not have enough CPU or memory to guarantee the virtual machine’s reservation, the move fails because admission control does not allow it. An error dialog box displays available and requested resources, so you can consider whether an adjustment might resolve the issue.
