    Is Dynamic Resource(DR) allocation possible in Hyper-V or i have to install SCVMM for performing DR operations?

    Please elaborate about what you mean by "Dynamic Resource Allocation"

     

    If you are thinking of the VMware DRS function where Host workload is constantly being re-balanced by taking advantage of Virtual Center and VMotion....that is not available in Hyper-V V1 (SCVMM does not enable it either).

     

    Operations Manager does (will) hook into Hyper-V and (theoretically) you could create rules that would perform this - however the move operation requires a breif pause and restart on the second Host in your cluster.

    Thanks Brian,

     

    I was looking for something similar to VMWare DRS.

    Can i do this?

    --> retrieve real time data using Performance counters

    --> dyanamically balance loads by adding and removing resources like memory and processor for an VM.

     

    are there any performance counters using which i can get data about memory and CPU usage for an VM?

    DRS like functions are not built in.  Could you hook-in to hte WMI interface for Failover Clustering and mimic the behavior?  Sure, why not!

     

    In regards to Performance Monitoring..

    You can use WMI to hook into Perfmon.

    This is not a Hyper-V specifc thing, but a Windows thing.

    Go, take a look at Performance Monitor - there is far more there to digest than you will want to base a decision on.

    By DR, what I mean is that, say for instance the VM requires memory or CPU resource. Can we give the resource to the VM while it is running and then the VM will start using the additional resource?

    Hyper-V RTM is not expected to allow changing RAM or CPU count while the VM is running.  You can adjust the proportion of CPU time that a VM is allowed to use while it's running, not sure if that is scriptable but likely. 

    thanks
