Hi there,

Sounds like that the operating system of the target Hypervisor did not register the class properly.

Can you use the WMI Tester against that host and execute this query?

SELECT
    Name, DepositedPages
FROM
    win32_perfrawdata_hvstats_hypervhypervisorrootpartition
WHERE
    Name = '_Total'

If the target Windows device still does not respond, this guide can help you to repair the target's WMI system.

Best regards, Felix

Hello,

I have the same problem in Windows 2016.

The class win32_perfrawdata_hvstats_hypervhypervisorrootpartition is not present in Windows 2016.

The command Get-WmiObject -List | Where Name -Match HvStats | Select Name not return win32_perfrawdata_hvstats_hypervhypervisorrootpartition

I think the class has been renamed to Win32_PerfFormattedData_HvStats_HyperVHypervisorPartition

Hello Romain,

Could you please perform these two queries using the WMI Tester and provide the results?

SELECT
    Name, DepositedPages
FROM
    win32_perfrawdata_hvstats_hypervhypervisorrootpartition
WHERE
    Name = '_Total'

SELECT
    Name, DepositedPages
FROM
    Win32_PerfFormattedData_HvStats_HyperVHypervisorPartition
WHERE
    Name = '_Total'

Kind regards,

Hello,

I do not want to highjack this thread, but I have the same problem as Romain described. I have tried the two mentionned WMI queries on Windows 2016 Standard setup as an Hyper-V server and the first returns and error. The second returns the Total result.

How do we get past that?

thanks

Hello, we are experiencing the exact same problem with the exact same error message (also on Windows server 2016 Standard) did you have an answer yet about this issue ? Thanks

Hi there,

The WMI classes needed to be recreated as the Hypervisor specific classes did not exist. Therefore, you can perform the steps described in this WMI Repair Guide. If it still does not work, you can send the WMI Tester Results listed above to [email protected].

Kind regards,
