For a while, the CloudStack community has been working on adding support for containers. ShapeBlue successfully implemented the CloudStack Container Service and donated it to the project in 2016, but it was not completely integrated into the codebase. However, with the recent CloudStack 4.14 LTS release, the CloudStack Kubernetes Service (CKS) plugin adds full Kubernetes […]
This feature allows CloudStack administrators to unmanage guest virtual machines (VMs) from their CloudStack infrastructure. Once unmanaged, CloudStack can no longer monitor, control, or manage provisioning and orchestration related operations on it. This feature is currently supported only on VMware. An interesting use case of this feature (when used in conjunction with the VM ingestion […]
Why Alex Mattioli, former Director of Architecture for a global telecoms giant, chose to join ShapeBlue Hello, I’m Alexandre Mattioli – a Cloud Architect at ShapeBlue. After a few months working here I’d like to share some views. Originally from Rio De Janeiro, Brazil, I moved to Europe in my mid-twenties in order to pursue […]
In a typical scenario prior to this feature, the administrator had to automate the process of setting hosts in maintenance before upgrading, usually using external automation tools. This feature allows administrators to perform the entire process within CloudStack, providing a flexible framework that allows defining custom scripts to execute on each host. CloudStack executes these scripts […]
Private VLANs have always been partially supported in CloudStack (for shared networks only), in versions prior to 4.14. Administrators could set up Isolated or Promiscuous PVLANs by creating their shared networks in which: Primary VLAN ID = secondary VLAN ID, for Promiscuous PVLANs Primary VLAN ID != secondary VLAN ID, for Isolated PVLANs CloudStack 4.14 […]
Introduction In a previous post, ShapeBlue’s Boris Stoyanov introduced a feature for KVM which allows administrators to register templates and ISOs without needing secondary storage as an intermediate cache. This feature is known as Direct Download in CloudStack. Without an intermediate cache, the templates and ISOs direct download registration process differs from the usual process, […]
This feature allows the sending of arbitrary additional VM configurations to user VMs on CloudStack and is supported by KVM, XenServer and VMware hypervisors. The administrator enables or disables this feature by the global configuration ‘enable.additional.vm.configuration’ which is disabled by default. To add a second layer of security, the administrator must explicitly set a comma-separated […]
The process of setting a host into maintenance in CloudStack requires an administrator to ask for ‘prepare for maintenance’, either via API or through the UI on a host. When CloudStack receives the request to prepare the host for maintenance, the host state is set to ‘PrepareForMaintenance’ and any VM running on the host start […]
This feature introduces an easy and integrated way to check the health of virtual routers (VRs) within CloudStack. With the help of these checks, administrators can monitor VRs and take any necessary action when a failure is reported. These health checks can be basic or advanced. Basic health checks include: Connectivity from the management server to […]
Hi – David Jumani here, maybe just a typical software engineer so far… I studied Computer Science and Engineering, and after graduation I worked at some of the biggest virtualization and networking companies (such as Vmware, Cisco and General Electric) developing cloud and on-premise applications, such as an incident co-relation engine (from which relationships can […]
