Microsoft Hyper-V Server 2008 R2 Hot Add / Remove Storage - How?

Hi all,

I've recently upgraded our Microsoft Hyper-V Server 2008 machine to R2,
primarily to get the hot add/remove of storage that was a listed feature
(although I swear the virtual machines are running faster in R2, which is
great!).

Unfortunately, I can't seem to get the hot add/remove functionality working.
When I performed the upgrade, it was a clean install with exported and then
imported VMs.

When I choose "Settings..." on a running virtual machine, and select the
(preconfigured when the machine was off) SCSI Controller, I can't choose
"Add" a new hard drive. The message is "some settings cannot be modified
because the virtual machine was running" as was the case in R1.

I've installed the R2 integration tools onto the guest OS, which is Windows
SBS 2008, though every time I insert the Integration Services disk I'm told
that "a previous installation has been detected. Press OK to upgrade or
repair this installation.". The first time I clicked OK of course, but it
continues to state that - but I think that is probably expected behaviour.
Not sure if there is a way to check the installed version of Integration
Services in Windows Server 2008?

I'm a bit stumped, to be honest, and I'm not sure whether I'm missing
something.

Any pointers will be greatly received. If there's any further information
that I can provide then just let me know.

Many thanks in advance,

Mark.

I haven't done the move to R2 as you did, but simply re-created my VMs by
creating a new VM and pointing to the existing VHDs, and I'm not seeing this
issue. When you create a new VM with R2, it automatically includes a SCSI
controller, and this at has hot add of VHDs enabled. Just as a test to see
if there's something happening because the VM originated in the original
Hyper-V server, I'd suggest doing a test on one of the VMs by deleting it,
and then add a new VM pointing to the old VHDs.
