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 […]

VMware Migration Improvements

VMware Migration Improvements | CloudStack Feature First Look

Migration of virtual machines 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 […]

vSphere Advanced Capabilities in CloudStack | CloudStack Feature Deep Dive

Introduction CloudStack vSphere integration has not kept up with the evolution of vSphere itself, and several functions can be performed natively by vSphere much more efficiently than by CloudStack. vSphere also has additional features which would be beneficial to the operators of vSphere based CloudStack clouds. This feature introduces support in CloudStack for VMFS6, vSAN, […]

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 […]

Boot into Hardware Setup | CloudStack Feature First Look

Users and administrators sometimes need to change the boot order of a virtual machine (VM) so that they can (for example) force a VM to boot from an ISO. However, sometimes the proxied console session does not appear until after the opportunity to enter the BIOS menu has passed. This feature allows an admin to […]

Enable unmanaging of guest instances | CloudStack Feature First Look

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 […]

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

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 […]

VM Ingestion | CloudStack Feature First Look

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 […]
