Share ISO from UI - CloudStack Feature First Look - Cover

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, a user or administrator must be able to update the permissions for an ISO via API and UI, being able to: Share the ISO with another account Share the ISO with another project Revoke the access to the ISO for an account Revoke the access […]

CentOS 8 Support | | CloudStack Feature First Look

As of 2021, CentOS 7 will be receiving maintenance updates only, and is end of life in 2024. Considering this, it is important that CloudStack supports CentOS 8 as a KVM hypervisor host and as a host for the management and usage servers. This support has been developed and will be included as of CloudStack 4.15. CentOS 8 uses a more recent QEMU version, Python 3 by default and deprecates several networking tools (such as bridge-utils), therefore a number of changes have been made: Python scripts related to setting up of management and usage servers and KVM agent have been […]

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 […]

Boot Into Hardware Setup

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 request that a VM boots into the BIOS or other hardware setup screen rather than into the operating system (OS). The nature of the setup depends on the underlying hardware version and the OS of the virtual machine, and can be BIOS or UEFI. This […]

Human readable byte sizes | CloudStack Feature First Look

CloudStack puts together many technologies to make managing large datacentres and its resources easy and efficient, but with many complex systems, it is not always evident what goes on behind the scenes. CloudStack has a verbose logging system built in that you can reference if you want to know what’s happening under the hood. This feature aims to make looking through those logs better for humans. In CloudStack logs, alerts, and events, data values are displayed in bytes. When dealing with gigabytes and terabytes, these values are long strings of numbers which become ‘unreadable’ (i.e. very difficult to understand or […]

Remote Console VMRC opening VM

noVNC Console Integration | CloudStack Feature First Look

There are a plethora of ways to connect to a remote system, from command-line based protocols like SSH, to graphical user interfaces such as RDP. One of the simplest ways to connect to the GUI of a remote system is via VNC (Virtual Network Computing), which transmits keyboard and mouse events from one computer to another, relaying screen updates back by returning a sequence of pixels which when put together produce an image or ‘frame’. Simply put, it allows one computer to delegate its GUI display to another machine for the sake of convenience. VNC is built upon the Remote […]

Cloud Computing Service - CloudStack

Send hypervisor host name via metadata | CloudStack Feature First Look

This feature allows admins to expose the hypervisor host name to a User VM instance either through Config Drive or Virtual Router, based on the user data provider chosen for the network offering on which the VM instance is deployed. To expose this information, the new Global configuration “global.allow.expose.host.hostname“ and the new Account scope configuration value “account.allow.expose.host.hostname” must be set to true. Once set, the hypervisor host name will be visible after VM creation, migration or reboot. If ConfigDrive is the user data provider, we need to firstly mount the config drive iso in the VM instance. After setting the […]

Cloud Management - CloudStack

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 feature) is being able to move guest VMs from one vCenter to another, by unmanaging it from one zone and then importing it into a different zone. It is also possible to perform any out-of-band operations on the VM (once unmanaged from CloudStack) directly through […]

Network Image - CloudStack Feature First Look

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 introduces some changes in the PVLAN support, by: Extending the existing support for shared networks and L2 networks (initially supported for the VMware hypervisor when using dvSwitches) Extending the PVLAN types to Isolated, Promiscuous and Community Allowing the administrators to explicitly select the PVLAN type […]

Direct Download png | CloudStack Feature First Look

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, which is: The template and ISO registration process uses secondary storage as an intermediate cache The zone SSVM handles the template or ISO download and stores it on the intermediate cache in secondary storage On VM creation, the template is copied into primary storage from […]
