Creating Virtual Hard Disks with Windows Virtual PC

Existing Virtual PC 2007 users who start using Windows Virtual PC may be startled by the lack of an obvious “Virtual Hard Disk wizard”.  But do not fear, the virtual hard disk wizard is still there – it is just hidden.  Or more accurately – it has been placed into more appropriate workflows.

The first place where the virtual hard disk wizard appears is when you are creating a new virtual machine.  If you select to Create a virtual hard disk using advanced options in the new virtual machine wizard you will seamlessly transition into the new virtual hard disk wizard:

The second place where the virtual hard disk wizard appears is from the virtual hard disk settings page, if you click on the Create… button:

Now, you may be wondering what to do if you want to create a virtual hard disk that is not associated with a virtual machine?  The answer is that you do not use Windows Virtual PC!  With Windows 7 virtual hard disk management is now part of the core operating system.  You can create virtual hard disks using either Disk Management or DiskPart:

Virtualizing Windows Essential Business Server

Thanks to Dugie for bringing this to my attention.  We have just published a document that outlines approaches and best practices for running Windows Essential Business Server in a virtual machine.  You can grab it here:

http://www.microsoft.com/downloads/details.aspx?FamilyID=933b2eb6-f3bb-47c1-a227-13bb2ccc0a94

Here is the abstract from the document:

This document provides guidance for virtualizing Windows® Essential Business Server (EBS) 2008 by using the Windows Server 2008 Hyper-V™ technology. Server virtualization allows you to install Windows EBS software on a single physical server reducing hardware, energy, and management costs. Virtualizing Windows EBS consists of the following steps:

• Choose a virtualization configuration
• Install and enable Hyper-V in Windows Server 2008
• Create and configure the virtual machines for Windows EBS
• Install Windows EBS on the virtual machines

This document covers virtualizing Windows EBS Standard

Multiple Seamless Applications with Windows Virtual PC

We have spent a lot of time telling people how Windows Virtual PC and Virtual XP mode will allow them to run incompatible legacy applications on Windows 7.  Unfortunately a number of people have come away with the impression that you can only do this with Virtual XP mode and that you can only run a single application at a time.

This is simply not true.

Using Windows Virtual PC you can access seamless applications from Windows XP, Windows Vista and Windows 7 virtual machines.  You can have multiple applications running seamlessly in a single virtual machine, and you can have seamless applications running under different virtual machines at the same time.

If you look at this screenshot:

You can see that I have Internet Explorer and a command prompt running under the same (Windows XP) virtual machine.  I then have Windows Live Photo Gallery running under a separate (Windows 7) virtual machine.  All three of these applications have been launched directly from my start menu in Windows 7.

Disabling Integrated Mode in Windows Virtual PC

Earlier this week I talked about integrated mode in Windows Virtual PC.  And there I mentioned that there are times that you may want to disable integrated mode.  You can do this on a running virtual machine by using the tools menu:

You can also permanently disable integrated mode by disabling integration features under the virtual machine settings:

But what if you need to disable integrated mode while a virtual machine is booting?  Normally when a virtual machine with integration components installed is booting on Windows Virtual PC you will see the following display:

But what if you need to boot into safe mode?  Or are trying to reinstall the operating system? 

Well, you can do this by hitting “SHIFT + ESC” on this dialog.  You will then get access to the virtual machine session with integration features disabled.  This can be very handy at times.

Changes to virtual machine snapshots in Windows Server 2008 R2

In Windows Server 2008 R2 we have made some surgical changes to the way virtual machine snapshots work and how they are exposed in the system in order to address some key customer pain points.  Changes include:

• You can now export a single snapshot from a virtual machine.  This works by selecting the snapshot in question and then selecting Export… from the Action pane.  We will merge all the snapshot disk data into a single new virtual hard disk – and the resulting exported virtual machine will look like a virtual machine with no snapshots that is identical to the snapshot you selected.  Note that the virtual machine needs to be turned off in order to perform this operation.
• Snapshot AVHD files are now created in the same directory as their parent VHD files.  Their names have also been updated to include the name of the parent virtual hard disk.  Both of these changes make it easier to identify and group snapshot files.
• When you open the settings for a virtual machine snapshot and look at the hard disk settings – you will see the name of the AVHD that is associated with that snapshot.  This helps you to map AVHD files to specific snapshots.
• You can now edit AVHD files in the edit VHD wizard.  This means that if you want to manually merge AVHD files to a new VHD to give to someone else – you can (note: be careful as you can cause problems if you merge back into the parent in this case).
• You can now directly attach an AVHD file to a virtual machine.  This is very handy if you have lost your virtual machine configuration and need to get data off of a snapshot file.

There is more work we need to do here, but hopefully this will help make snapshots more flexible and usable.

What is Integrated Mode in Windows Virtual PC?

If you use Windows Virtual PC you will see “integration features” being mentioned.  These are enabled once you have the latest integration components installed, and can be enabled or disabled at will – but what are they?

When the integration features are enabled we are actually using Remote Desktop to connect to the operating system running inside the virtual machine.  This allows us to take advantages of many of the technologies built into remote desktop:

• The ability to display seamless Windows from the virtual machine
• The ability to redirect smart cards and printers to the virtual machine
• The ability to share folders to the virtual machine

We have worked hard to do this while maintaining a level of performance similar to that of Virtual PC 2007, and in many cases the performance is better.

However there are still times when you might need to disable integration features.  The most common is if you are running a program that needs to use DirectX or needs to change the resolution of the display – as neither of these are possible to do when using remote desktop.

Note that if you disable integration features you lose access to shared resources (smart cards, printers, folders, etc…).

Microsoft Mediaroom uses Hyper-V to virtualize IPTV

This is a bit old – but if you have not seen this already go check out:

http://www.microsoft.com/Mediaroom/PR/VirtualizationPR.aspx

The summary is that we have launched Microsoft Mediaroom with virtualization to enable IPTV providers to reduce their costs by consolidating hardware and increasing utilization with Hyper-V.

The neat thing about this – from my point of view – is that it demonstrates that Hyper-V is fully capable of handling such a demanding work load.  I also have heard from customers who are running their corporate VoIP servers in Hyper-V quite happily.

Creating virtual machines with Windows Virtual PC

If you have read about Windows Virtual PC and Windows XP mode, you may mistakenly think that Windows Virtual PC can only be used for running applications in Windows XP mode.  While this is one of the major features, Windows Virtual PC allows you to create multiple virtual machines and use them for multiple operating systems.

The process of creating virtual machines has been improved a bit since Virtual PC 2007, so I thought I would go over the process:

1. From the start menu, open the Windows Virtual PC folder and select Virtual Machines.
2. From the Virtual Machines folder, click on Create virtual machine.
3. On the first page of the Create a virtual machine wizard you can specify the Name and Location for the virtual machine.
4. Next you can configure the amount of Memory for the virtual machine, and whether Networking will be enabled or not.
5. Finally you can choose to create a new virtual hard disk or to use an existing one.

After completing this 5 step the virtual machine will be created, and you can install the operating system you want to run.  On the virtual hard disk configuration page of the create a virtual machine wizard you also have the option of selecting to create a virtual hard disk using advanced options.  If you select this option you will then see a number of extra pages that allow you to create a dynamically expanding, fixed-size or differencing virtual hard disk of any size that you want.

Using Windows Virtual PC to run 16-bit applications on 64-bit Windows

I have had some people ask me whether you can use Windows Virtual PC – with its integrated Windows XP Mode – to run older 16-bit Windows programs on a 64-bit platform.  The answer is “Yes!”.  Here you can see a screen shot of SkiFree running on my laptop:

In the foreground you can see the error message that I receive if I try to run SkiFree directly on my laptop (which is running the 64-bit version of Windows 7).  In the background you can see SkiFree running under Windows XP mode.

This can be very useful if you have legacy 16-bit applications that you need to use, but want to take advantage of 64-bit computing.

Problem with Hyper-V Beta Components on Windows Server 2008 SP2

We recently published KB2000048 which outlines that if you try to run a Windows Server 2008 virtual machine, with beta integration components, on a Windows Server 2008 SP2 system – the virtual machine will fail to boot.

Ordinarily this would not be a big issue, but the real concern is that any virtual machine created with Windows Server 2008 RTM install media will automatically have the problematic beta integration components.

The best way to avoid this problem is to ensure that you install the RTM version of the Hyper-V integration components in all virtual machines prior to installing SP2 on the physical computer, and after installing SP2 you should use installation media with SP2 integrated into it to create new virtual machines.

If you cannot do this the article above provides you with a list of possible workarounds.

Processor Compatibility in Hyper-V R2

With the release candidate version of Windows Server 2008 R2 and Microsoft Hyper-V Server 2008 R2 we have added a new feature called “Processor Compatibility”.  The purpose behind this feature is to allow you to live migrate virtual machines between different processor types (from the same manufacturer) without any downtime.

This functionality is configurable through a simple check box on the processor settings page for the virtual machine. If you select to  enable your virtual machine to Migrate to a physical computer with a different processor version then we make sure that the virtual machine can be migrated.

We do this by hiding advanced processor features from the virtual machine, so it can run on any version of the processor.

Some points of interest:

• This does not allow you to move between AMD and Intel.  Just between different processors from the same manufacturer.
• While this has been designed for live migration – it extends to make saved states and snapshots compatible as well.  It also helps if you are just using quick migration.
• There is no extra hardware requirement for this functionality.  Your processor does not need to have AMD Extended Migration or Intel Flex Migration technology.  There are also no BIOS or hardware changes that you need to make.
• By enabling this feature you do lose access to some advanced CPU features. The features you lose are as follows:
  • AMD: SSSE3, SSE4.1, SSE4.A, SSE5, POPCNT, LZCNT, Misaligned SSE, AMD 3DNow!, Extended AMD 3DNow!
  • Intel: SSSE3, SSE4.1, SSE4.2, POPCNT, Misaligned SSE, XSAVE, AVX
