XCP-ng Windows PV tools announcements

@clip This often happens with Driver Verifier enabled, what do verifier /querysettings and verifier /query say?

@dinhngtu Further trialing showed this issue is confined to one host and all its VMs (including Linux ones) - please consider this issue resolved and not related to Windows PV tools (incidentally, in this particular case there were no verified drivers enabled and no drivers currently verified on the Windows VMs). Apologies for mistaking this as a Windows PV tools issue.

Has anyone had their antivirus go crazy with this version? I am getting tons of messages saying this file has a virus:

"C:\Program Files\XCP-ng\Windows PV Drivers\xenplus\xenplus.exe"

@archw Which AV is causing the warning, can you report it as a false positive?

@dinhngtu
Something called "Elpha Secure" ...none of our other antivirus shows it being bad but I wanted to ask around before I unflagged it.

Not compatible with the "Manage Citrix PV drivers via Windows Update" option. You must disable this option before installing.

Changes since 9.2.385

NEW: Group Policy support (see the extras/admx directory in the source code tree). Supported policies include:
- Hide the tray icon
- Disable all features that allow controlling the VM from the host
Improved: Better network performance.
Improved: System reliability improvements on driver upgrade failure.
- On an upgrade failure, the installer will remove all Xen drivers to ensure that the system will keep operating, and to allow you to safely uninstall the existing driver package.
Improved: Remove obsolete Windows Update devices and don't block installation because of them.
Fixed: Fix further data corruption bugs during memory snapshots and backups.
- This driver version significantly narrows the corruption window. However, fully fixing all known corruption issues requires further work in other XCP-ng components. Please keep an eye on the XCP-ng blog for updates.
Fixed: Fix loss of VBD connection after storage migration.
Fixed: Improve reliability of the clipboard service.
Fixed: Improve reliability of the VIF IP configuration feature.
Fixed: Reliability fixes on VMs with many vCPUs (>64).
Fixed: Many other driver reliability fixes.

Hi,

Just a FYI, I had requested for XCP-ng Windows PV tools to be added to the winget repo.

Since 11 november 2026 the tool has been added to the repo.
So it is possible to update/instal the tool via winget.

Hope this helps some users with automation.
