🎉 The XCP-ng Windows PV Drivers are now fully signed and ready for production use! 🎉

Get the newest releases here: https://github.com/xcp-ng/win-pv-drivers/releases

Read our announcement blog post for more information.

Below are historical release notes pertaining to older testsigned versions of the drivers:

(Historical release information) Hello all,

Version 9.0.9065 of the new Windows PV drivers has been released.

This release brings a security fix for XSA-468 (CVE-2025-27462, CVE-2025-27463, CVE-2025-27464) and clipboard support in our Rust Guest Agent.

This driver release is for testing purposes only and not for production use. It requires putting the system into testsign mode. (only applies to the drivers themselves, not XenBootFix/XenClean/mitigation scripts; you can use these tools separately without any configuration)

We are actively working with Microsoft to get the drivers signed (which is a slow process). An announcement will be made as soon as a Microsoft-signed build is available.

Download the release here: https://github.com/xcp-ng/win-pv-drivers/releases/tag/v9.0.9065

Release notes are below:

To download XenClean, click here. The ISO download also includes a copy of XenClean and XenBootFix. Remember to carefully read XenClean docs before use.

Before Installing

  • This driver release is for testing purposes only. Not for production use!
  • Not compatible with the "Manage Citrix PV drivers via Windows Update" option. You must disable this option before installing.
  • Make backups/snapshots before installing!
  • The drivers in this package are testsigned and require enabling testsigning mode. Disable Secure Boot, then run the included script testsign/install.ps1 as Administrator to configure Windows and install the necessary signer certificates. Your VM will reboot automatically.
  • Note: For this release only, extra files (mitigation scripts, testsign scripts) are not included in the ZIP (only in the ISO file). Find them in extras.zip.

Changes since 9.0.9030.0

  • IMPORTANT: Security fix for XSA-468 (CVE-2025-27462, CVE-2025-27463, CVE-2025-27464). Check the XCP-ng docs or blog announcement for more details.
    • Mitigation and host-side detection scripts are included in the repository and release package.
  • NOTICE: Xen PV disk drivers have been reenabled by default on new installations. If you want to enable Xen PV disk drivers coming from 9.0.9030, you may do so from Add/Remove Programs.
  • NEW: Clipboard support in Rust Guest Agent.
  • Fixes: More improvements to XenClean to support older drivers.
  • Updated branding to follow Vates/XCP-ng brand guidelines.
  • Build automation support.

Changes since 8.2.2-beta

  • This release is based on upstream 9.1-series drivers, which includes the PV Mouse/Keyboard driver and PV Console Driver. You can access the PV console with the following command from a XCP-ng host:

xl console -t pv <vmname>
  • New installer with clean uninstallation and multiple install/uninstall safety checks.
  • New XenClean utility for cleanly removing XCP-ng and Citrix drivers.
  • Multiple driver stability fixes.
  • Volume Shadow Service Provider is no longer included. (XCP-ng 8.1 and newer no longer support quiescent snapshots)
  • Check out the new Rust-based Xen Guest Agent included in our package! We're looking to bring back even more features to the agent.
  • Older Windows versions are no longer supported. The driver requires at a minimum Windows 10 1607 or Windows Server 2016.

XenClean/XenBootFix 9.1.152 have been released.

This release fixes VSA-2026-012 (DLL sideloading vulnerability in XenClean and XenBootFix).

If your VM is running 9.1.146, you don't need to update. You just need to replace any XenClean and XenBootFix files you downloaded.

The package\XenClean and package\XenBootFix directories contain fixed versions of the aforementioned tools.

package\XenTools-x64.msi has not changed from version 9.1.146, and is only provided as a convenience. The installation MSI does not include the fixed XenBootFix.

You must use the one from package\XenBootFix or download the tool directly from GitHub!

The next release of the XCP-ng Windows Guest Tools will contain a fixed version of XenBootFix.

Get it here: https://github.com/xcp-ng/win-pv-drivers/releases

The XCP-ng 9.1 tools installer will block installation and indicate an error whenever XenClean is needed.

Prior to installing xcpng-winpv-9.1.100.0-Release-x64.zip, I ran Invoke-XenClean.ps1 that came with the package.

Is is still true that, in order to install (upgrade to) xcpng-winpv-9.1.145.0-Release-x64, I have to run XenClean.exe again and then run the new installer?

Its just a lot of reboots, resetting static ip addresses etc.

As a result, the version information in the guest agent (which does the reporting) was not updated.

Seems that the 9.1.146 version still reports 9.1.145-77 to XO. It is listed as the correct version in "Installed programs" within the guest (Windows server 2025).

Version 9.1.146 Release of the Windows PV tools has been released.

Download the latest release here: https://github.com/xcp-ng/win-pv-drivers/releases

It will be integrated into the XCP-ng built-in tools ISO after a test period of 2 weeks.

This is a small revision to fix issues when installing on certain Windows installations. Only the installer and XenClean were changed; the binaries inside stay the same.

If you're already on 9.1.145, upgrading is optional.

Changes since 9.1.145

  • Fixed: Fix issues when installing on certain Windows installations.

A new package will be released to address this.

The issue on this VM was we were installing as non-admin. All others were admin by default.

Good catch

That worked for one of our Windows 11 VMs.

It's checking for "ERROR: The system cannot find the file specified. -2147024894", which is why it's failing. What if you specified the command this way, with a backslash?

Normally it's supposed to self-destruct but maybe something went wrong there.

We always get:
ScreenShot 2026-03-18 at 13.38.04.png

We have rebooted before installing the tools: same issue
We have run Xenclean before installing: same
We have run Xenbootfix: same

Basically we'tried everything. I haven't opened an official ticket yet because the answer here might help others.

I just realized, that this is a timing issue as well. Sometimes the copy&paste works after a slight delay, where the console seems non-responsive (e.g. cannot move the mouse cursor). After something like ~15 secs things work as expected. For subsequent copy&paste operations the delay seems to be much lower.

On a fully patched XCP-ng 8.3 host using Xen Orchestra 5 (actually the 6.2.2 build, but the v5 interface) allows only to copy the clipboard from the VM to the browser, not the other way around.

No issues.
