• Support for resizing the root volume of virtual machines in Apache CloudStack (limited to increasing size only).
• Whenever a respective hypervisor introduces new features, adjustments are required in Apache CloudStack to accommodate these changes. Following the release of VMware ESXi's feature to increase root disk size, we have implemented code in CloudStack to support this capability.
• Exempting network sub-net from usage calculation.
• Several companies utilize CloudStack for delivering Infrastructure as a Service (IaaS). To accurately bill customers, network traffic is used as one of the parameters. In this work, We enhanced CloudStack by introducing the capability to exclude virtual machines connected via specific sub-net ranges (from being billed).
