@manilx Try installing the .msi from an elevated powershell prompt. That worked for one of our Windows 11 VMs.

@pdonias Sure thing. I can test it in my test environment.

@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.

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.

@archw I can confirm. That is exactly the behaviour I see with my Windows VMs.

@dinhngtu Thanks for the pointer. Yes, it seems that the root cause also makes routes disappear. Howerver, that the routing information is gone is sadly not mentioned explicitly. May be something to add to your docs as well.

Caution when updating tools: Verify interface IP configuration and routing entries.

Just did a couple more tests. Here are my findings:

• Upgrading the tools from v9.3.3 to v9.4.1 does preserve the routing table.
• Upgrading the tools from v9.2.1 to v9.4.1 does not preserve the routing table.

Here are a couple of powershell commands used for testing:

Get-NetRoute -PolicyStore PersistentStore
Get-NetAdapter
New-NetRoute -DestinationPrefix "10.10.0.0/24" -InterfaceIndex <ifIndex> -NextHop 10.10.0.254

@pdonias Sure thing. I can test it in my test environment.

@DustinB Not IP assignments, I am talking about static routes. See e.g. https://learn.microsoft.com/en-us/powershell/module/nettcpip/get-netroute

Here is another interesting fact: After installing the new tools (v.9.4.1) my static routes in Windows were all gone. Definitively a good way to loose connectivity to your domain controller. And that's why you have good monitoring and store things in Ansible et al. ...

@dinhngtu On the machine where it worked, the option "Manage Citrix PV drivers via Windows Update" was not enabled. Seems that my older BIOS Windows 10 VMs have that option enabled. On all UEFI VMs the options is disabled.

As I wanted to go and check that is present in the templates, I realized that the Windows Templates are gone from Xen Orchestra v5.106.4???
