Powershell – Install RSAT-Hyper-V-tools fails on Windows Server 2012 R2 Server Core

hyper-vpowershellvirtualizationwindows-server-2012-r2windows-server-core

When I try to install Rsat-Hyper-v-tools with powershell command:
add-windowsfeature rsat-hyper-v-tools -includeAllSubFeature

It fails with error saying that:

The source files could not be downloaded. Error: 0x800F0906

Also :

CategoryInfo: InvalidOperation: (@(Vhd=; Credent...Name=Localhost):PSObject) ..
FullyQualifiedErrorId: DISMAPI_Error__Cbs_Download_Failure

I have tried googling issue without success. Might be something to do with Windows updates or not.

Im running hyper-v on this PC and cannot install tools to control VMS. Is there other way to start VM's in case I can't use another PC to start them? For example I am running Domain controller on this VM host, and if it goes down, I can't start it from another PC because of no access rights(DC down). Or can i use PS remote command with that local pc administrator account?

Okey went to look in to one russian forum(i think) and there was english command:

Add-windowsfeature hyper-v-powershell

Which successfully installed powershell cmdlets (phew).
