Edit a VM - Managed VMware


The screens you can view in CloudCreator will vary, depending on your assigned role. See Roles and Permissions for more information.


Relationship Between VM Values

CloudCreator allows you to change the configuration of a VM by altering the values. The availability of what can be changed, depends on whether the VM is powered on or off.


The table below describes the relationship between each VM value and when it can be modified. 


Value Can be modified when: Description
Memory  VM is Powered Off

The Memory value affects the Virtual CPU value. The Virtual CPU entitlement is half of the Memory value (in vGB) rounded up. For example:

  • If the Memory vGB is 8, then Virtual CPU is a maximum of 4.
  • If the Memory vGB is 5, then the Virtual CPU is a maximum of 3 (2.5 rounded up). 
Virtual CPU VM is Powered On
  • If the VM is still powered on, this is the only field you can edit.
  • Your possible CPU values are limited to multiples of the current Cores per Socket quantity.
  • When the CPU value is changed, the 'display' fields of Cores per Socket and Number of Sockets will automatically adjust. 
  • To select all possible CPU values, and modify the Cores per Socket value, you will need to power down the VM first. 
Virtual CPU  VM is Powered Off
  • Changing the Virtual CPU value will automatically recalculate the valid values for the Cores per Socket field.
  • The Virtual CPU value is calculated as follows: Number of sockets x Cores Per Sockets = Virtual CPUs.  
Cores per Socket VM is Powered Off

Changes to the number of Cores per Socket of the VM (either increase or decrease) can only be performed while the VM is powered off. 


Change the Configuration of a VM

Follow the steps below to change a VM configuration.


1. Navigate to the Compute Overview page (shown below). This shows all your resources grouped by the service types you are subscribed to.


2. Next to the Service Type and Location of the VM you want to edit, click the blue Resource Number. For example, the screenshot below shows the selection of all the Managed VMware VM's located at the WPD Data Centre. 



3. The Compute Details page appears and shows a list of all the VMs at the selected Data Centre. From this page you can:

  • Use search to locate the VM you want to edit.
  • Or remove and add filters to further refine the results.
  • Assign cost centres and resource categories.
  • Click on a row to the view the properties of a VM. 

To find out more about how to use the features of this page, see The Compute Detail Page 



4. Locate the VM you want to delete by using the search function and filters. Once you have located the VM, you can also view its properties by clicking on the row. 


5. Before you can change the Virtual CPU and Cores per Sockets fields, your VM must be powered off. To check that your VM is powered off, select Power Controls and if necessary, select Power Off. 

The screenshot below shows that the VM needs to be powered off. 


Note: The options that appear may vary, depending on the service you are subscribed to. See Manage a Compute Resource to find out about the control options available.



6. Once your VM is powered, off, select the 3 dots to access the menu. Then select Manage Virtual Machine > Edit Virtual Machine. 


A notification will appear if the VM cannot be modified due to a snapshot, or if there is a request for modification in place (eg. an outstanding DFA request or Service Desk request).



7. The Edit VMware Virtual Machine screen appears. Here you can alter the MemoryVirtual CPU, and Cores Per Sockets. For more information, hover over the tooltip icon  or see Relationship Between VM Values above. 



  • CloudCreator does not offer the option of renaming the Virtual Machine itself.
  • The Cores per Socket must be configured with an amount that is a factor of the total number of vCPUs.
  • If vCPU is in multiples of Cores per Socket, this field is not reset. Instead, the Number of Sockets field is recalculated as per the calculation above. 
  • If vCPU is not in multiples of Cores per Socket, the Cores per Socket is reset to 1, and the Number of Sockets field equals the number of vCPUs as per the calculation above.



8. Once you have changed the configuration, click Confirm. A confirmation will appear. Click Confirm again. 



9. A notification will appear at the top of your screen. Click the bell icon  to view.


All VM events also show on the Recent Events panel on the CloudCreator dashboard. These include VM removal, power on and off, rollback, failures, etc.
