Q6. What should I pay attention to renew VM with change package or addition resources request?

A6: There are some important remark need to pay attention to before submitting a change VM package with renewal subscription or additional resources(CPU/RAM/Disk) request:

(i) You must delete any existing VM snapshot before submitting the change VM package or additional resources request.

(ii) For any change VM package request to a larger VM package, the base OS disk will be expanded at VM configuration level. But the OS administrator need to re-scan disk on Linux or Windows for OS to recognize the expanded disk size.

(iii) For any change VM package request to a smaller VM package, the base OS disk will keep in same size.

(iv) For any additional resources (CPU/RAM/disk) request, there will be two type requests:

-(a) Full period of additional resources (for long term): Additional resources (CPU/RAM/disk) can be added to the full period of remaining subscription period (e.g. remaining period is 4 months, additional resources will be added to full period of remaining 4 months). Subsequent VM renewal will be based on the VM with additional resources. 

- (b) Partial period of additional resources (for short term): Additional resources (only CPU/RAM) can be added to the partial period of remaining subscription period (e.g. remaining period is 4 months, additional resources will be added to partial period of 1month only). Please send request to itscloud@hku.hk to discuss the partial period and the necessary charging cost. As the additional resources will be removed after the partial period end (i.e. VM will be reverted to original configuration after partial period), subsequent VM renewal will be based on the original VM without additional resources. 

(v) For any additional resources request or change VM package request to a larger package, it may possible to trigger OS reboot at 4:00am at next consecutive day after final approval complete, when the additional  CPU/RAM/Disk is added to the VM
