Hello all,
Version 9.2.350 Release of the Windows guest 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 major release brings a new Windows guest agent with many new features, plus multiple other improvements.
To download XenClean, click here. The installer downloads also includes a copy of XenClean and XenBootFix. It is not necessary to run XenClean when upgrading from previous versions of the XCP-ng Windows guest tools, unless prompted by the installer. Remember to carefully read XenClean docs before use.

@kagbasi-wgsdac Normally, this issue has already been fixed upstream since a long time.
XS tools 9.4.0 is pretty old, you should update to 9.6.0 which should contain a newer Xenbus balloon driver.
Better yet, you can switch to the XCP-ng tools (as you've done), since the XCP-ng tools are what we now recommend for all Windows guests.
A new version of the XCP-ng tools is coming out soon with lots of improvements.
You can check for the driver version by running this command on the host:
xe vm-param-get uuid=<VM UUID> param-name=PV-drivers-version
For XS 9.6.0, I'd expect it to report xenbus: XenServer 9.1.13.23.
@poddingue FWIW I've seen the same on FC44 as well, but I don't yet know where it came from.
I've taken a quick look, looks like it'll be solved as part of the Windows guest agent overhaul, so please look forward to that.
@abudef An overhaul of the guest agent is coming. We're considering adding some kind of update notifications as part of that overhaul, but it'll take some time to suss out the details. Autoupdating the Xen drivers is potentially disruptive and I'd prefer avoiding outages arising from an update coming at a bad time.
Hello all,
Version 9.1.200 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 release brings bug fixes and improvements to the PV drivers.
@taghjichte A PCI card should be more reliable than an USB card in most cases. Do you have realtime/low latency audio requirements or is it simply for normal playback (music etc)? Virtualization will work fine for typical playback but for low latency, you might want some specific tuning. Also, you might want to test DPC latencies with the Xen drivers when there's I/O activity.
@jr-m4 Could you check if your VMs are using XenServer or XCP-ng tools?
Hello all,
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
This seems to be specific to XenServer guest agents?
Hello all,
XenClean 9.1.148 Prerelease is now available with a fix for error 1605 during execution.
This is a XenClean-only prerelease.
https://github.com/xcp-ng/win-pv-drivers/releases/tag/v9.1.148
Thanks for the report. This is a known issue and will be fixed in the next full release.
In the meantime, I've released an interim XenClean 9.1.148 that will resolve this issue.

Hi, it's a known issue on newer CPUs: https://docs.xcp-ng.org/troubleshooting/windows-pv-tools/#bsod-0x3b-system_service_exception-on-newer-intel-cpus
What's your CPU Vendor value shown in xl dmesg?
Never mind, I missed your log: CPU Vendor: Intel, Family 6 (0x6), Model 143 (0x8f), Stepping 8 (raw 000806f8)
@kagbasi-wgsdac Blind guess, your ISO SR is not connected to one of the hosts?
@archw XenClean is not needed when upgrading; it's only needed when switching tools vendor, or when switching from the old XCP-ng 8.2 tools.
The XCP-ng 9.1 tools installer will block installation and indicate an error whenever XenClean is needed.
@probain Yes, that's expected as there were only changes in the installer and XenClean/XenBootFix, the drivers and guest agent binaries included in 9.1.145 and 9.1.146 are the exact same. As a result, the version information in the guest agent (which does the reporting) was not updated.
Hello all,
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.
Recent Windows patches also changed the exit code of schtasks.
A new package will be released to address this.
