I have installed Windows Server 208 R2 SP1 beta release on Hyper-V machine to exercise dynamic memory feature.
But I am not able to get success in using this feature.
I have tried following steps:-
1. Created virtual machine and configured dynamic memory feature as
Min RAM - 512 MB and Max RAM 1024 GB and memory priority is set to high.
2. Installed windows OS on virtual machines and installed integrated services.
3. Started virtual machine
4. Observed memory usage in virtual machine task manager
5. Ran one test application consuming high memory on virtual machine
6. Observed memory usage in virtual machine task manager -> performance tab
7. It starts increasing memory usage but goes maximum till 500 MB or so. After that test application gets crashed. Ideally test application should have not been crashed. It should have got memory beyond our min allocated memory 512 MB i.e. dynamically increased memory.
Has anyone observed this issue?
Can anyone suggest how to exercise this feature?
Can you confirm what OS you are running in the VM?
Do you see memory change in the "Current Memory" columen of that VM HYper V Manager Console?
OS installed on VM is windows server 2008 standard SP1 x64.
No there is no change seen in Current Memory column in Hyper-V Manager Console. If min memory assigned to VM is 512 MB then Current Memory remains 512 MB only. Ideally memory should have been increased dynamically as required by test application. However CPU usage shows increase in Hyper-V Manager Console.
It may be possible that Integeration Service in the VM is not updated, Try reinstalling the Integeration Services and reboot the VM and check. :)
We tried reinstalling integration services on VM; also rebooted the machine but no success.
Windows 2008 Standard edition OS on Virtual machine is not supported for dynamic feature. We changed OS on virtual machine and it worked.
