Currently, CloudStack allows admins to configure the dynamic scaling of CPU and RAM for the VMs using a global or zone level setting “enable.dynamic.scale.vm” and through a “Dynamically Scalable” flag in templates. However, the global or zone setting applies to all VMs in a particular region or zone and there may be virtual hardware or […]
When upgrading Apache CloudStack (ACS) to a newer version one must manually register new SystemVM templates before upgrading the packages. Failing to do so means having to roll back the database to the previous version, register the new template and start the upgrade again. We’ve developed a process (available as of CloudStack 4.16.0) to automate […]
CloudStack administrators are currently able to add annotations/comments on hosts, domains or virtual machines. This is useful as administrators may comment on the actions taken on those entities, allowing other administrators to know why actions were taken. This new functionality (available from CloudStack version 4.16.0 onwards) extends the scope of the comments feature to users, […]
A CloudStack resource is typically identified by its name or description, and when creating and managing resources, zones are often named by their geographical location, team/company name for domains, accounts, projects and so on. However, as icons and images are generally easier to quickly identify we wanted to improve the user experience by providing the […]
Since CloudStack 4.14 it has been possible to import virtual machines (VMs) from a vSphere cluster directly into CloudStack, which introduced the concept of managed and unmanaged VMs. Managed VMs are those controlled by CloudStack, whereas unmanaged VMs have been either deployed directly on the hypervisor or removed from CloudStack (using the unmanageVirtualMachine API). To […]
In December 2020, Red Hat announced major changes to the roadmap of its CentOS distribution, including the early end of life of CentOS 8 in December 2021. Due to this sudden and unexpected change, new Linux distributions have been developed as possible alternatives to CentOS, which are binary-compatible with Red Hat Enterprise Linux 8 (RHEL8). […]
Want to start or stop a VM (Virtual Machine), or delete an offering in CloudStack? No big deal. However – what if you need to delete 20 offerings, or stop 20 VMs? Having to perform the same operation on each individual item is time-consuming, laborious and can be frustrating. Bearing this in mind, we’ve come […]
Apache CloudStack 4.15 introduced several new capabilities for vSphere, including support for datastore clusters. Following production use of the new features and feedback from users, an opportunity for improvement was noticed. If a storage pool is added or removed from the datastore cluster in vCenter, to see those changes in CloudStack it is necessary to […]
For primary storage, CloudStack supports many managed storage solutions via storage plugins, such as SolidFire, Ceph, Datera, CloudByte and Nexenta. There are other managed storages which CloudStack does not support, one of which is Dell EMC PowerFlex (formerly known as VxFlexOS or ScaleIO). PowerFlex is a distributed shared block storage, like Ceph / RBD storage. […]
The latest version of XCP-ng – the opensource hypervisor based on XenServer – XCP-ng 8.2 was released in November 2020, and is the first long term support (LTS) version. As such it will receive support and updates for the next 5 years compared to only a year for a standard XCP release. The hypervisor is […]
