With 16,000+ participants from 111 countries and 715 open-source organizations participating, Google Summer of Code is one of the most popular programs which helps students enter the technology world and gain new skills. GSoC pairs students with mentors from participating open-source organizations, allowing students to face the real world of software development and coding. For […]
There is currently enormous market demand for Infrastructure as a Service (IaaS), with organisations looking for the right solution to host their applications and workloads, build a high-performing test/dev environment or deploy a hybrid cloud solution. Others, like telcos and MSPs, need to offer a full range of services to their customers, and the cloud […]
A lot of work has gone into the CloudStack UI recently, and it is now a modern, role-based UI that not only gives a fresh look to CloudStack but also makes development and customisation much easier. In this blog, I provide guidance on how to customise the UI, and have classified customisation into two categories […]
The latest version of XCP-ng – the opensource hypervisor based on XenServer – XCP-ng 8.2 was released in November 2020, and is the first long term support (LTS) version. As such it will receive support and updates for the next 5 years compared to only a year for a standard XCP release. The hypervisor is […]
When a network is created in CloudStack, it is by default not provisioned until the first VM is deployed on that network, at which point a a VLAN ID is assigned. Until then, the network exists only as a database entry. If you wanted to create and provision a network without deploying any VMs, you […]
Migration of virtual machines between physical hosts or clusters is essential for cloud operators, allowing them to perform maintenance with little or no downtime, or balance compute and storage resources when necessary. CloudStack supports both live and cold migration (if supported by the hypervisor), and most hypervisors allow VM and volume migration in some form […]
If you are a system engineer managing shared networks and deploying virtual machines with CloudStack, you should be aware that currently there is no option to assign a specific IP address for the Virtual Router. The router is assigned the first free IP address. For many engineers, this might be annoying, as you are not […]
Since the addition of CloudStack Kubernetes Service, users can deploy and manage Kubernetes clusters in CloudStack. This not only makes CloudStack a more versatile and multifaceted application, but also reduces the gap between virtualization and containerization. As with any step in the right direction, it came with a few challenges, and one of them was […]
Vendors of virtual appliances (vApp) for VMware often produce ‘templates’ of their appliances in an OVA format. An OVA file will contain disc images, configuration data of the virtual appliance, and sometimes a EULA which must be acknowledged. The purpose of this feature is to enable CloudStack to mimic the end-user experience of importing such […]
Projects have proven to be a boon in organizing and grouping accounts and resources together, giving users in the same domain the ability to collaborate and share resources such as VMs, snapshots, volumes and IP addresses. However, there is a limitation. Only accounts can be added as members to projects, which can be an issue […]
