CloudStack Feature First Look: Enable unmanaging of guest instances

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 […]

CloudStack Feature First Look: Enable sending of arbitrary configuration data to VMs

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 […]

CloudStack Feature First Look: VM Ingestion

Apache CloudStack has proved itself to be a great cloud orchestrator and is probably one of the best open-source platforms available for deployment of new IaaS environments. However, until now there has been little or no support for importing an existing cloud environment with all its resources and entities into CloudStack. This is going to […]

SolidFire with CloudStack

Aside from traditional storage solutions, CloudStack has supported managed storage for some time. In this article, we will touch on SolidFire support in CloudStack 4.13 and lay out the exact steps needed to add SolidFire to CloudStack as Primary Storage (for VMware, KVM and XenServer). We will also explain the difference between the “SolidFire” and […]

Trillian: Flexible, On-Demand Cloud Environment Creation

Marvin: “I think you ought to know I’m feeling very depressed.” Trillian: “Well, we have something that may take your mind off it.” Marvin: “It won’t work, I have an exceptionally large mind.“ Trillian was born from the need for us to create environments which we could run CloudStack’s Marvin test framework against, but the […]

Recovering From a vCenter Failure

While, in my opinion VMware’s vSphere is the best performing and most stable hypervisor available, vCenter obstinately remains a single point of failure when using vSphere and it’s no different when leveraging vCenter in a CloudStack environment.  Therefore, very occasionally there is a requirement to rebuild a vCentre server which was previously running in your […]

CloudStack global settings with VMware

In this article, Paul Angus Cloud Architect at ShapeBlue looks into a few interesting settings when using CloudStack to orchestrate VMware environments Working with CloudStack 4.3 and VMware 5.5 in our lab recently, I came to using some very interesting global settings which renewed a project I had on the back burner… vm.instancename.flag This global […]

Understanding CloudStack’s Physical Networking Architecture

  Understanding and configuring the physical connections of a host in a CloudStack deployment can at first be very confusing. While Software Defined Networking (SDN) is set to greatly simplify some aspects, its integration within CloudStack is not fully mature yet and it won’t be the right solution for everyone. In this article, Paul Angus, […]

How to beat the VMWare Vtax.

Citrix CloudStack eases the financial impact associated with the “vTax,” the term used by many in the cloud and virtualization communities to refer to the latest update to the VMware vSphere 5 licensing model that added costs to customers’ existing cloud and virtualization implementations.  Since CloudStack can support multiple hypervisors in the same cloud, VMware […]
