Hello all,

Version 9.1.145 Release of the Windows PV tools has been released.

(Despite the name, it's still signed; I simply dropped the "Signed" moniker)

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 the new XCP-ng Standard VGA Display Driver as well as multiple bug fixes to all Windows drivers and guest tools components.

Changes since 9.1.100

• NEW: The XCP-ng Standard VGA Display Driver is now included in the package.
• Improved: XenClean is now a single executable that's more convenient to use.
• Improved: Better uninstalling of existing drivers.
• Fixes: Automatic time sync is now disabled by default on new installations. NTP sync with W32Time is recommended instead.
  • To disable time sync on an existing installation, use the Modify button in Installed apps.
• Fixes: Xen Guest Agent now operates correctly during driver restarts and upgrades.
• Fixes: Fix uninstallation of individual drivers.
• Fixes: Improve stability and efficiency of Xenbus and Xenvbd.

No issues.

We noticed that using the XCP-ng Windows PV tools brakes some functionality of the shared clipboard. 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.

[dinhngtu]

@conitrade-as There should be a fix for that in 9.1.145. Could you try it?

[conitrade-as]

@dinhngtu That indeed seems to work. 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.

[dinhngtu]

@conitrade-as Sounds like a problem somewhere in the clipboard stack, I'll look into that.
