      @dinhngtu Hopefully before the next updates to xcpng. Rolling pool update moves all VM's....

      Does this bug clear itself after a VM reboot? Or has the tools to be reinstalled? Is it only cosmetic or does it affect the running VM?

      Havne't tried this myself and as we have moved all VM's to these new tools I'd like to be aware of what I can expect.

        @manilx It's purely cosmetic and will clear on reboot.

            Whats the difference between this one and the the one created by "managementagentx64-9.4.2.msi" downloaded from "http://downloadns.citrix.com.edgesuite.net/17528/managementagent-9.4.2-x64.msi" or https://www.xenserver.com/downloads#lightbox-20160?

            As of right now, using "managementagentx64-9.4.2.msi" I get "Management agent 9.4.2-178 detected" with the latest Citrix/xenserver.com drivers.

            Is it better to start using this signed build of the XCP-ng Windows PV drivers?

            Thanks!

              @archw xcp-ng tools are developed by Vates with many improvements over the citrix tools that align with xcp-ng.

              "Dont forget to clean out the old citrix tools before installing." - https://github.com/xcp-ng/win-pv-drivers/releases

                Thanks for the advice! I just did one.....lots of rebooting required.

                After you run xclean, it then reboots. When it comes back, there is no mouse so, unless you can do everything from keystrokes, you have to reboot. When it comes back, you can then install the new drivers. It then reboots and now you can reset your original ip address (if it was a static IP address).

                  @archw and forgot to type "Not compatible with the "Manage Citrix PV drivers via Windows Update" option. You must disable this option before installing."

                    In regards to statement few posts above that XCP-ng tools are developed by Vates, does that mean that Vates builds them from scratch or modifies Citrix/XenServer ones?

                    I am thinking about switching to "XCP-ng windows guest tools 9.0.9137'', production is currently on "XenServer VM Tools for Windows 9.4.2".

                      @dom0 They are built from scratch using these components:

                      • Upstream Xen Project PV driver sources, which includes contributions from Citrix, Vates, Invisible Things Lab among others, and where we are one of the maintainers;
                      • The Rust guest agent, which is developed by us;
                      • The installer, packaging and tooling is completely our own.

                      The main repo is here: https://github.com/xcp-ng/win-pv-drivers
