&lt;p&gt;As I am on the subject of dream requests, being able to support conversions from Physical to Vitual with a seemless tool like VMware's &amp;quot;Converter&amp;quot; utility would be a lot less painful than the Microsoft route.&lt;/p&gt;
&lt;p&gt;Oh and heck, why not ask for a solution only the uterly insane might request, compatibiliy with actual VMware virtual machine files; or perhaps a means to convert VMDK to VHD integrated into the non-Beta version of Hyper-V?&lt;/p&gt;

I have a MOSS development environment running under Virtual PC 2007 with Office 2007, etc. When I boot it under Hyper-V it tells me the hardware has changed significantly and that I have to re-activate Windows.

&lt;p&gt;I made W2003 R2 SP2 Std Edt 32bit VM under Virtual Server 2005 R2 SP1, migrated VHD to Hyper-V, installed Integration Services, created new machine, et voila! It worked well.&lt;/p&gt;
&lt;p&gt;Then I was asked to move it back to Virtual Server 2005 R2 SP1. I've tried with Uninstalation of Intergation services, but didn't work. Then I mounted VHD as drive letter and replaced HAL.DLL with old one. IT WORKS !!!!&lt;/p&gt;</description></item><item><title>Prise en main d'Hyper-V : 3 - Installer Hyper-V</title><link>http://blogs.technet.com/jhoward/archive/2008/02/28/are-vhds-compatible-between-hyper-v-and-virtual-server-and-virtual-pc.aspx#3039341</link><pubDate>Fri, 18 Apr 2008 14:41:55 GMT</pubDate><guid isPermaLink="false">d5e57398-b9ef-4490-9955-07cbb4e4a80d:3039341</guid><dc:creator>pascals.blog</dc:creator><description>&lt;p&gt;Nous voici donc &amp;amp;#224; la troisi&amp;amp;#232;me &amp;amp;#233;tape de notre prise en main d'Hyper-V sur une configuration&lt;/p&gt;
