    • RE: RealTimeIsUniversal - Windows VM - PV driver does not work

      With DWORD value the PV drivers work.
      But the PV driver´s instability with QWORD value is worth to "be corrected". (by my opinion)

      Solved.

      @dinhngtu "The drivers don't like that value being a REG_QWORD" - if you mean by that: "The PV driver doesn´t work correctly with qword value" then I will try set it to REG_DWORD even every documentation on Internet and in Microsoft demand QWORD.

      Then I will put result here.

    • RealTimeIsUniversal - Windows VM - PV driver does not work

      We installed new VM (Windows 11 - 24H2) in XCP-ng (latest-version, from source).
      Everything works fine, XEN tools work fine

      Management agent 9.4.1-160 detected and works

      We set-up in windows registry QWORD value HKLM\CurrentControlSet\CurrentControl\TimeZoeInformation\RealTimeIsUniversal=1
      (We need this settings for many computers/VM with dual boot)

      1. The VM cannot boot with using PV drivers - it use QEMU drivers.

      2, in XOA the VM reported "management agent NOT installed" (In windows is reported as installed)

      • XOA is unable report memory usage

      If we tried to remove (manualy, by GPO or by script) this registry entry, VM is unable to boot (error: unaccesible boot device) or crashed (rarely).

      I think it is bug in management agent/PV drivers for Windows.
      Have you any solution for using PV drivers in Windows with setting BIOS/UEFI using real time clock as UTC?
