I'll change it to report something like "Windows 11 Professional 64-bit" instead. Any other guest information you'd like to see reported here?
-
@dinhngtu Better to report it Windows11/Windows Server 202x
-
@dinhngtu I would prefer some standardized OS information for Windows systems, similar to this info:
Get-ComputerInfo | Select-Object OsName, OsVersion, OsBuildNumber, OsArchitecture OsName OsVersion OsBuildNumber OsArchitecture ------ --------- ------------- -------------- Microsoft Windows Server 2025 Standard Evaluation 10.0.26100 26100 64-bit -
@dinhngtu Is it impossible to report the correct Windows version? Seems to be the "correct" solution....
-
Sorry for the confusion, I was posting the output from my Windows 11 computer...
On Server 2022 for example, it will report "Windows Server 2022 Datacenter 64-bit" instead. So the OS name should be correct wrt. client/server editions, i.e. it will not report as Windows 11 on Server 2025.
-
@dinhngtu From my point of view this would be fine
So the systems can be distinguished even when the buildnumber is the same. -
Got a weird bug on these.
Used xenclean to remove Citrix 9.4.1 drivers, installed the 9.0.9137-2 . Now if I live migrate a VDI, the agent gives up on that VM. Drivers are all working, just the agent needs reinstalling. Only got one pool to test it on, but its the same on all four hosts.
Three VMS I migrated disks on;
From Management Agent Detected before VDI migrated to agent missing after migration completion;
All three are Server 2019 VMs.
Any similar known issues?
-
@spelon Yes, it's known. I'll try to fix that in the next release.
-
@dinhngtu Hopefully before the next updates to xcpng. Rolling pool update moves all VM's....
Does this bug clear itself after a VM reboot? Or has the tools to be reinstalled? Is it only cosmetic or does it affect the running VM?
Havne't tried this myself and as we have moved all VM's to these new tools I'd like to be aware of what I can expect.
-
@manilx It's purely cosmetic and will clear on reboot.

Whats the difference between this one and the the one created by "managementagentx64-9.4.2.msi" downloaded from "http://downloadns.citrix.com.edgesuite.net/17528/managementagent-9.4.2-x64.msi" or https://www.xenserver.com/downloads#lightbox-20160?
As of right now, using "managementagentx64-9.4.2.msi" I get "Management agent 9.4.2-178 detected" with the latest Citrix/xenserver.com drivers.
Is it better to start using this signed build of the XCP-ng Windows PV drivers?
Thanks!

@archw xcp-ng tools are developed by Vates with many improvements over the citrix tools that align with xcp-ng.

@Henrik
Thanks for the advice! I just did one.....lots of rebooting required.After you run xclean, it then reboots. When it comes back, there is no mouse so, unless you can do everything from keystrokes, you have to reboot. When it comes back, you can then install the new drivers. It then reboots and now you can reset your original ip address (if it was a static IP address).

@archw and forgot to type "Not compatible with the "Manage Citrix PV drivers via Windows Update" option. You must disable this option before installing."
-
In regards to statement few posts above that XCP-ng tools are developed by Vates, does that mean that Vates builds them from scratch or modifies Citrix/XenServer ones?
I am thinking about switching to "XCP-ng windows guest tools 9.0.9137'', production is currently on "XenServer VM Tools for Windows 9.4.2".
-
@dom0 They are built from scratch using these components:
- Upstream Xen Project PV driver sources, which includes contributions from Citrix, Vates, Invisible Things Lab among others, and where we are one of the maintainers;
- The Rust guest agent, which is developed by us;
- The installer, packaging and tooling is completely our own.

@dinhngtu Updated from previous version running on 8 Windows Server 2022 VM's across HomeLab & Office.
No issues.

Thank you for explanation!
My production servers are currently running XenServer VM Tools for Windows 9.4.2. Would you recommend switching to XCP-ng tools?
