Ben the Virtual PC Guy did a blog post a while ago where he showed how to get files out of a running machine, and I made a follow up where using a non Hyper-V host to get the files.

Today I read on a forum that they where discussing how to get a folder and the files from a virtual machine running on Windows 8 client Hyper-V by enabling and fiddeling with the network. In some cases you do not want to enable networking on that guest to the Win8 host and then you can use the way that Ben showed.

Or you can use an VHD that you first connect to the Win8 host and then copy the files and when you are done you can disconnect it from the host machine and connect it to the virtual machine, with this approach instead of the snapshot you can also add files from the host to the virtual machine and the other way around.

So With PowerShell I first create an VHD and mount it to the Host, create a partition and format it and then I copy the data I want to transfer and then also mount it to the VM.

New-VHD -Path c:\temp\MobileData.vhdx -Dynamic -SizeBytes 10GB | Select-Object Path | Mount-VHD
Get-Disk | where PartitionStyle -eq "RAW" | Initialize-Disk -PartitionStyle MBR -PassThru | New-Partition -UseMaximumSize -AssignDriveLetter -MbrType IFS | Format-Volume -Confirm:$false | Select-Object DriveLetter | ft -AutoSize
Copy-Item C:\ToVM -Destination E:\ -Recurse
Dismount-VHD C:\temp\MobileData.vhdx
Add-VMHardDiskDrive -VMName VMTest -Path C:\temp\MobileData.vhdx -ControllerType SCSI -ControllerNumber 0 -ControllerLocation 0

As you might know, why I use the SCSI controller is to be able to hot-add the virtual hard disk to the VM while it is running and not having to shut it down 🙂

The first time in the VM I have to do some massage on the disk before it appears but the next time the VM´s OS recoginize it and it can be used directly.

Get-Disk | where OperationalStatus -eq "Offline" | Set-Disk -IsReadOnly $false
Get-Disk | where OperationalStatus -eq "Offline" | Set-Disk -IsOffline $false
New-Item -Path E:\ToVM\ToHost -Type directory

And as you can see in the screendump above of the virtual machines folder with the files and also you can see that I can add data inside the VM to my virtual disk. If I would just use the Set-Disk -IsOffline $false I would get a volume that was write protected and here I wanted to add files and folders from the virtual machine also.

And when I am done moving files I can easily disconnect the disk from the VM from the host by using the following PowerShell cmdlet

Remove-VMHardDiskDrive -VMName VMTest -ControllerType SCSI -ControllerNumber 0 -ControllerLocation 0

This move folder and files way also works on the Windows 2012 Hyper-V!

Looking at the features in the Virtual PC compared to the client Hyper-V there are at lest two features I miss in the later,

• Easily copying files between virtual machine and host
• An network that can share the hosts without any extra manual configuration with the bridging creating a NAT solution out of the box.

Well you can´t get everything you wish for and some things you can create workarounds for 🙂

Last week on the NIC keynote we could hear Jeffrey Snover talk about Windows 2012 and also that the preferred version when installing is Core, but then you will not have the Hyper-V manager locally (yes you could use the PowerShell module….).

So how do we enable our management station for remote Hyper-V tasks…

If you have a Windows 2012 you can easily just enable the Remote Server Administration Tools for Hyper-V and that preferably with PowerShell

And if you want to check if you have the Hyper-V management features installed you can use the Get-WindowsFeature

I usually also add the Failover cluster RSAT feature also to be able to manage the cluster.

Add-WindowsFeature RSAT-Hyper-V-Tools -IncludeAllSubFeature
Add-WindowsFeature RSAT-Clustering -IncludeAllSubFeature

If you want to add the Hyper-V tools in a Windows 8 you would guess that you have to use the DISM tools and there are some DISM cmdlets, You might have noticed that the Hyper-V tools are not part of the RSAT package for windows 8 this as the client Hyper-V role is part of the OS. But either I am doing something wrong or someone in Redmond has not thought this part through regarding the enabling of features in PowerShell for Win8!

because when I try the following Cmdlet with parameters

Enable-WindowsOptionalFeature -FeatureName Microsoft-Hyper-V-Tools-All

The PowerShell console barf out an error because when trying to add the Management tools with the powershell cmdlet I get info that it needs a parent feature which would be the Hyper-V feature and in this virtual windows 8 client that is not what I want,

When using the Control Panel, Add/Remove software/Windows Features you can add the Hyper-V Management tools in your Windows 8 without adding the Hyper-V Platform!

I will pursue this with some smart PowerShell gurus and see if they have an answer to why this happens 🙂

In the meantime good luck in creating your management pc!
