CS 4.2 + VMware - Dynamic VM scaling problems
Hi all, I'm currently on a CS 4.2 + VMware vSphere 5.1 infrastructure, and I'm having issues with the dynamic resource scaling for Linux virtual machines; all the Linux templates are based on 64bit operatins systems. All the CS parameters are correct (enable.dynamic.scale.vm and scale.retry are configured), the template have been generated by enabling the required flag (Dynamically Scalable), and on vSphere I can see activated both the options for CPU and RAM hot plug; anyway, I'm not able to expand the resources on both CS and VMware sides if the virtual machine is up and running. I have no problems when working with Windows Server templates, for which I'm able to expand resource when the machine is powered on. Any suggest / help / idea? Thanks in advance, Gaspare

Does the underlying operating system support CPU/memory hotplug? Can you dynamically scale a VM just using vSphere 5.1? --David
Re: CS 4.2 + VMware - Dynamic VM scaling problems
Hi David, thank you for your support. The distros are different (CentOS 6.4, Ubuntu 12...), all the OS are 64bit versions. If I try to perform the operation directly on vSphere, for a VM deployed by CloudStack, I'm not able to execute the task; if I deploy a Linux machine directly from VMware I can expand the CPU/RAM resources. For this reason I believe that the problem could be on the CS 4.2 side. Thanks in advance for your reply.
