Dynamic-Scaling-VMs

Granular Control of Dynamic Scaling of VM’s CPU/RAM

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 […]

SystemVM Templates - Upgrade Imrpovements

SystemVM template – Upgrade Improvements

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 […]

Enable Bulk Actions via the CloudStack UI

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 […]
