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 […]

Share ISO from UI | CloudStack Feature First Look

CloudStack supports sharing templates and ISOs between accounts and projects through the API ‘updateTemplatePermissions’ and sharing templates through the UI. However, prior to version 4.15, it was not possible to share ISOs from the UI. This feature introduces support for sharing ISOs through different accounts and / or projects via the UI. With this feature, […]

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 PVLAN support on L2 networks | CloudStack Feature First Look

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 […]

Direct Download agnostic of the storage provider | CloudStack Feature First Look

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, […]

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 […]

Hosts stuck in PrepareForMaintenance state | CloudStack Feature First Look

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 […]

VR Health Checks | CloudStack Feature First Look

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 […]

Openvswitch with DPDK support on CloudStack – Part 2 | CloudStack Feature Deep Dive

Introduction In my previous post, I described the new ‘Open vSwitch with DPDK support’ on CloudStack for KVM hosts. There, I focused on describing the feature, as it was new to CloudStack, and also explained the necessary configuration on the KVM agents’ side to enable DPDK support. DPDK (Data Plane Development Kit) (https://www.dpdk.org/) is a […]

Openvswitch with DPDK support on CloudStack | CloudStack Feature Deep Dive

Introduction This blog describes a new feature to be introduced in the CloudStack 4.12 release (already in the current master branch of the CloudStack repository). This feature will provide support for the Data Plane Development Kit (DPDK) in conjunction with Open vSwitch (OVS) for guest VMs and is targeted at the KVM hypervisor. The Data […]
