XCP-ng Windows PV tools announcements

Henrik

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

@Henrik
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

@dinhngtu

Thank you for explanation!

My production servers are currently running XenServer VM Tools for Windows 9.4.2. Would you recommend switching to XCP-ng tools?

dinhngtu

@dom0 Yes, the Vates tools are our recommended guest tools for XCP-ng going forward.

Would it be possible to either have direct links to the exe's without them being zipped? Or list the version number of the xen-guest-agent.exe?

I'm installing these through Ansible (see code below). And it would be way cleaner if either of those two wishes could be true.

    - name: Install Xen Guest tools on Windows hosts
      when: ansible_system == "Win32NT"
      tags: xcp_ng
      block:
        - name: Install Xen Guest Tools
          when: ansible_virtualization_type == "xen"
          block:
            - name: Copy over Latest Xen PV drivers
              ansible.windows.win_copy:
                src: "XenTools-x64_{{ xen_guest_agent_version }}.msi"
                dest: "C:\\Users\\{{ ansible_user }}\\Downloads\\XenDrivers-x64.msi"
                force: true

            - name: Install XenDrivers if the version isnt already created
              ansible.windows.win_package:
                path: "C:\\Users\\{{ ansible_user }}\\Downloads\\XenDrivers-x64.msi"
                creates_path: C:\Program Files\XCP-ng\Windows PV Drivers\XenGuestAgent\xen-guest-agent.exe
                creates_version: "{{ xen_guest_agent_version }}"
                arguments:
                  - /quiet
