Customizing new CloudStack UI - Cover

Customising the CloudStack UI

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 – basic and advanced. Basic Customisations Users can customise the UI by means of this configuration file: /etc/cloudstack/management/config.json to modify theme, logos, etc. as required. These changes can be made while the CloudStack management server is running, and the changes can be seen immediately with […]

CloudStack Support for XCP-ng

XCP-ng 8.2 LTS Support Added to CloudStack

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 getting more and more popular in the open-source world thanks to its modern and user-friendly UI, scalability, live migration capabilities and security level. XCP-ng 8.2 comes with a wide range of new capabilities including UEFI support, openflow controller access, native support for Gluster, ZFS, XFS, […]

L2 Persistent Networks & enhancement of Isolated Persistent Networks

L2 Persistent Networks and enhancement of Isolated Persistent Networks | CloudStack Feature First Look

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 would need to create a persistent network. With persistent networks, you can deploy physical devices like routers / switches, etc. without having to deploy VMs on it, as it provisions the network at the time of its creation. More information about persistent networks in CloudStack […]

VMware Migration Improvements - CloudStack Feature First Look - Cover

VMware Migration Improvements | CloudStack Feature First Look

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 or another. VMware vMotion provides both live and cold migration of VM and volumes. By leveraging vMotion with the APIs migrateVirtualMachine, migrateVirtualMachineWithVolume, migrateSystemVm and migrateVolume, migration of user and system VMs and their volume(s) can be performed easily in CloudStack. However, until now CloudStack had […]

Shared Networks - How to specify VR - CloudStack

Specify VR IP in Shared Networks | CloudStack Feature First Look

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 able to make the selection by yourself. Moreover, you would prefer to hold the inventory under control and select the IP address to be assigned by yourself. In this article, we present a new feature in CloudStack, which make the management of shared networks easier. […]

CloudStack Kubernetes Service – Cluster Auto-scaling | CloudStack Feature First Look

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 manual scaling of the cluster. Automating this process by monitoring cluster metrics may address this issue, but Kubernetes strongly advises against this. Instead, it is recommended that Kubernetes itself make these scaling decisions, and specifically for , Kubernetes has the ‘Cluster Autoscaler’ feature – a […]

Support Virtual Appliance OVA Templates in VMware | CloudStack Deep Dive

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 an OVA directly into vCenter, the end result being a virtual appliance deployed with the same configuration data in the virtual machines descriptor (VMX) file as would be there if the appliance had been deployed directly through vCenter. The OVA will contain configuration data regarding […]

Role Based Users in Projects - Add Account to Project

Role Based Users in Projects | CloudStack Feature First Look

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 if we only want to add a single user of an account to a project. To address this, we’ve enhanced the way project membership is handled to facilitate addition of individual users. Adding users to projects and assigning project-level roles In order to restrict users […]

Dynamic Roles Utility - Add Account

Dynamic Roles Utility | CloudStack Feature First Look

CloudStack has more than 600 APIs which can be allowed / disallowed in different combinations to create dynamic roles for the users. The aim of this feature is more effective use and management of these dynamic roles, allowing CloudStack users and operators to: Import and export roles (rule definitions) for the purpose of sharing. Create a new role from an existing role (clone and rename) to create a slightly different role. Use additional built-in roles (to quickly create read-only and support users and operators), such as: Read-Only Admin role: an admin role in which an account is only allowed to […]

Support for XCP-ng 8.x - CloudStack Feature First Look

Support for XCP-ng 8.x | CloudStack Feature First Look

XCP-ng (an open-source hypervisor based on XenServer) has been supported in CloudStack for some time, and support for XCP-ng 8.x will be available from CloudStack 4.15. From an operational perspective, there is no visible change in the UI or API – XCP-ng 8.x hosts can be added to CloudStack during zone deployment or by using the addHost API / UI. With guest OS mappings added for XCP-ng 8.x, once added all VM operations can be performed on such hosts just like any older XCP-ng hosts unless they are functionally not available on XCP-ng 8.x. It should be noted that with […]
