      Did you specify the VM Switch in the VM?

      Did you disable VMQ?

      Did you change any advanced features away from default?

        Morning everyone.

        We're running Hyper-V version 6.1.7601.17514 on a Dell Poweredge 2900 on Windows Server 2008 R2. This is a Server 2012 R2 VM running on a 2008 R2 Host (unsure if that matters but just giving as much information as I can). I was asked to look at it as a second pair of eyes but nothing immediately jumped out at me until I saw this:

        You'll notice that I can't expand the network adapter. I think this is due to the fact that the host machine is running 2008 R2, but I haven't actually attempted to run a Hypervisor in it--every other VM host we have is 2012.

        Is this correct?

          Check and make sure the vSwitch is an external vSwitch.

          Is this the only VM on this host?

            Any conflicts with that mac address on the network?

                It's external

                They are using this as a very small file server in addition to the VM but it's the only VM hosted currently.

                  Why does it have a static MAC? I know nothing of Hyper-V setups, but that seems odd unless they P2V'ed the VM.

                    I had it set to dynamic before, it was just a test.

                      Have you tried removing the virtual NIC and reinstall it?

                        Yes I did. I'm wondering if this has anything to do with the fact that the Dell Poweredge 2900 was one of the first generations to support Hyper-V.

                          Can you see the vSwitch in the Hyper-V setup itself?

                                I really think that this is because the host is 2008 R2 but I don't have enough experience to definitively say that with zero doubt.

                                  I'm not sure if Hyper-V 2008 R2 supports a Server 2012 VM or not. that could be the issue.

                                      Well the good thing is - you can upgrade the hypervisor for free. shut the VM down, copy it somewhere else, wipe the host, reinstall Hyper-V 2016 server, copy the VM back, tada. 🙂

                                        @Dashrender Yeah that's basically my plan. I'm glad I rad into this. My co-worker tried and I had never attempted to do this before. It's good to know.

                                          My bigger question is - why was he deploying a single VM onto a 5 year old hypervisor, when upgrading/installing the latest is free?

                                          Oh, I'd skip 2012R2 at this point as well, and go straight to Hyper-V 2016.

                                            @Dashrender I'm not sure. I think it was for a timeclock so they just wanted something setup quickly. I don't even know if he's the person who did the initial install. We took over for another company and are still finding stuff.--
