      I noticed that Hyper-V was having a problem creating snapshots on my new Hyper-V Server 2016 system. This is not a good thing. The snapshot functionality is how all backup systems function.

      I did a little digging and it appears that while CentOS 7 includes some version of these drivers natively, they are now outdated and not updating.

      [root@bnasc ~]# /sbin/modinfo hv_vmbus
      filename:       /lib/modules/3.10.0-514.6.1.el7.x86_64/kernel/drivers/hv/hv_vmbus.ko
      license:        GPL
      rhelversion:    7.3
      srcversion:     B18736993819DBB43C5F7B7
      alias:          acpi*:VMBus:*
      alias:          acpi*:VMBUS:*
      depends:
      intree:         Y
      vermagic:       3.10.0-514.6.1.el7.x86_64 SMP mod_unload modversions
      signer:         CentOS Linux kernel signing key
      sig_key:        EE:3B:C2:53:44:A6:71:F6:D7:76:4A:5C:FD:83:AB:4B:AF:DB:E7:4D
      sig_hashalgo:   sha256
      [root@bnasc ~]#
      

      Looks like version 3.10? Microsoft has released version 4.1.3 for CentOS/RHEL 7.3
      https://www.microsoft.com/en-us/download/details.aspx?id=51612

      So before I deal with manually downloading and everything. does anyone have a script to get this?

        MS doesn't have a repo for this?

          No, they want you to download an ISO and tar.gz file.

            I thought the newer CentOS and Ubuntu versions already came with LIS pre-installed or built into the kernel or whatever?

              That is the version I show above. It is outdated from the native repo, obviously.

                Here is Microsoft's official grid for LIS support.

                  So because It seems the native is supposed to support Server 2016 core, then how come I cannot make a snapshot.

                    If I shut down the VM, I can make checkpoints and backups with no errors.

                    This is also happening on a fully updated Server 2012 R2 DataCenter + Hyper-V system.

                      I'm running some CentOS 7 proxy servers. One of them is running on Server 2012 R2 DataCenter + Hyper-V as well.
                      Backups via Windows Server Backup and checkpoints work just fine while the machine is running.

                      Here's what mine shows... not exactly the same as yours, but may be some help? I don't mind taking a checkpoint and updating if it may help get some info if needed.

                          @Tim_G oh, yours is 7.2. I never had a problem until recently. maybe it is 7.3 that is the problem.

                            @JaredBusch I'll restore a backup of that VM and turn it on, on my test network... update it and update LIS if needed. I'll let you know if I run in to the same issue as you.

                              Nope, I just logged onto a machine at another client. They are Hyper-V Server 2012 R2.

                              This client everything works normally

                                @JaredBusch Yeah that says v 7.3 too. I'll try that update plan I mentioned and let you know.

                                  So WTF, I have one that works fine using 7.3 native LIS on Hyper-V Server 2012 R2, and one that fails on Hyper-V Server 2016 or Server 2012 R2 DataCenter.
