It also failed for me! CloudStack 4.2.0 + XenServer 6.2 & VMware ESXi 5.0. I did configure enable.dynamic.scale.vm = true, and install XenServer/VMware Tools in the VM templates. I also checked Dynamically Scalable option in registering templates. On the XenServer side, I followed the instructions on wiki and this YouTube video to set up Dynamic Memory Control(DMC). https://cwiki.apache.org/confluence/display/CLOUDSTACK/Dynamic+scaling+of+CPU+and+RAM http://www.youtube.com/watch?v=ZUtwGqhQD1M
Here're my results. I no longer have the detailed logs available.: CentOS 6.4 / XenServer: CPU scale-up works immediately, but memory scale-up requires a VM reboot to take effect. CentOS 6.4 / VMware: ERROR: Requested memory limit is beyond the hotadd memory limit for this VM. Windows 7 / XenServer: ERROR: vm does not have tools to support dynamic scaling. Windows 7 / XenServer: ERROR: vm does not have tools to support dynamic scaling. Scale down: ERROR: Only scaling up the vm is supported. (This is expected as wiki says) I performed all these operations via UI, not API. ------------------------------------------------------------------------------------------- Yu-Heng (Ryan) Lei, Associate Researcher Chunghwa Telecom Laboratories / Cloud Computing Laboratory ryan...@cht.com.tw or ryanlei750...@gmail.com On Fri, Dec 20, 2013 at 1:04 PM, Shanker Balan <shanker.ba...@shapeblue.com>wrote: > On 19-Dec-2013, at 6:44 pm, Harikrishna Patnala < > harikrishna.patn...@citrix.com> wrote: > > > Hi, > > From cloustack we need to specify whether Xenserver tools got installed > on the template. while registering a template we see a checkbox > “IsDynamic”, this represents whether tools installed or not. > > > > Please check the template that you have used to deploy vm contains > Xensever Tools.
