We need to be able to resize the root disk. We have several cases were the costumer uses only the root disk of an instance either with Windows either with Linux. And we just discovered that using apiculus portal is not possible to resize the disk. But using the cloudstack is a very simple thing, you just need to stop the vm and resize the root disk. We need also make sure that this increased size will be billed.
Thanks
