I am not getting the dynamic memory option in Hyper V Manager, it is just showing my static memory.

I am running Hyper V role on a Windows Server 2008 R2 SP1 Enterprise Core install.
I have two guest OS's that are both Windows Server 2008 R2 SP1 Enterprise (full install)

I have verified SP1 on the host and the guest
I have installed the Integration Services for the guest systems.
I am running the Hyper V manager from a Vista computer (cause I haven't taken the time to upgrade it to Win7 yet!)

What might I be missing?

Thanks for any tips!

did you install the integration services before or after you upgraded to SP1?

My copy of Server 2008 R2 has SP1 included, so I guess you would say after....

also -- you can only adjust or enable the dynamic memory settings when the VM is powered off.   Are you trying to change the settings while the VMs are on?

EshuunDara - Yes, VMs are off.

dariusq - yes, I have gone through the steps, but when I get to the step that says "On the Memory page, under Memory Management, click Dynamic."  I have no dynamic option.

So, you have installed on both host and VM. You have installed new integration components on VMs. You have rebooted host and VMs?

Yes, yes, and yes.  At least I haven't missed something obvious!?

If you have followed all steps should be listed. Really seems like a step has been missed.

Are you doing the management from a SP1 machine?

I got it figured out.  The problem was that i was running  the Hyper V Manager from a vista box.  I switched over to a win 7 sp1 box and sure enough, there was my dynamic option.   So it seems you can not manage dynamic memory from  Hyper V manager running on a Vista box.   I'll be finally upgrading tomorrow I think.

Hi kievinhsieh,

you were on the right track with your question.  I figured it out just before your post.  The management also has to be done from a sp1 machine (Win7,Server 2008 R2).

Older versions of the management software don't know about the new options.

In all my searching I never did find any documentation that the manager had to running on a SP1 machine.  It makes sense, just would be nice if it was documented somewhere...
