Invalid namespace "rootvirtualization" on Hyper-V 2012

Running the following command on a fresh Hyper-V 2012 server:

get-wmiobject -namespace “rootvirtualization” -Query “select * from Msvm_ConcreteJob”

produces this errorerror:

Get-WmiObject : Invalid namespace "rootvirtualization"

    + FullyQualifiedErrorId : GetWMIManagementException,Microsoft.PowerShell.Commands.GetWmiObjectCommand

I'm lost as to what the issue would be, shouldn't this namespace be part of a standard Hyper-V install? Is there some powershell module I need to install?

Solution 1:

It seems a backslash is missing from the namespace path. Rather than "rootvirtualization" the path should be "root\virtualization"

UPDATE: For 2012 R2 the namespace is "root\virtualization\v2"
