    Re: Hypet-v 2012 high traffic

    What sort of high traffic - network, processor, disk ???
    (EDIT, re-reading your original, it is network)
    Can you give us examples for the guest VM and for the host server

    Note I have deleted your identical post in the Server 2008 forum

        This is like pulling teeth....

        Can you give us some more details, preferably with examples.

        Also what are the HW specs of the physical server and the VM?

          While working on a Hyper-V 3.0 deployment recently, I noticed that all of the virtual machines running on all newly built hypervisors were showing an unhealthy high ping latency trying to ping anything from local network to VMs. but pings from inside the varied from 1ms all the way past 300ms.
          Hard ware is Dell Poweredge 720.
          thanks

            Sigh... never mind....
            There are only about 200 different variations you can get for a Dell PowerEdge, and you haven't bothered giving us VM specs, or what actual latency you consider to be "unhealthy"

            What does perfmon give you?
            What does pinging the host give?
            What other networking equipment is involved?
            How do the host and guest VMs connect (shared connection?)

            Or should I just get my crystal ball out and attempt to guess answers

              Sorry, I'm not accept your response, i think this cause is clear enough, if you don't have technical response please keep other participle try to answer.
              thanks.

                But no one else can answer without more detail, which is what Ossian is attempting to get you to provide.

                Your problem could be related to a physical switch that is between your VMs and the client PCs which connect to them.

                Your problem could be related to the drivers used for the physical NIC in the Dell server which host your VMs.

                Your problem could be related to how much RAM you have in your Dell host vs the RAM settings for your VMs.

                Your problem could even be related to disk access times on your Dell host, which governs how well your VMs can operate.

                If you can't/won't answer, we can't help.

                  Hi ayman.se,

                  Advise is given here on a voluntary basis and we always endeavour not to jump to conclusions, so offer technical advise accordingly. I disagree with your response and the cause is not clear. The root cause is what we are helping with and recommendations have been made accordingly.

                  From what I can see, you have been asked a number of questions and we have already responded to some of your questions. If you still need support on this matter, please respond to questions you have been asked otherwise let us know if you don't, so we can look into closing this post.

                  You have also been given recommendations around what to use in the meantime to get to a root cause and would expect feedback from you around those as well, which helps you get to the root cause and results you post back to us, would then help us channel technical responses accordingly.

                    Re: Hyper-v 2012 high traffic

                    hi ayman.se,

                    I'm going to try and see if I can help you figure this out. I may well ask alot of questions but that's because I simply don't have any knowledge of your specific environment and setup.

                    firstly, could you explain what you identify as "high latency"?
                    For instance, I regard latency of 35-50ms for my Azure virtual servers to be acceptable, but above 75ms to be high.
                    Or, I regard latency of 250-300ms between my home office and my London client (hey, it's 10,000 miles!) to be acceptable, but 400ms to be high
                    So it's a bit relevant. Especially if you consider the type of network connections between the two endpoints.

                    Secondly, if you have two virtual guests on the one physical Dell host and they ping each other, what is the latency?

                    Thirdly, what if you ping the actual console of the physical host? (IE, on esx it would be the management interface vnic that you use for viconsole, and hyperV it would be the host's IP address you could use to RDP)

                    Fourth, what if you png from the physical host, to the guests it hosts?


                    Hoping your answers can help me address this wih you
