Answer 1

To resolve this Issue, please follow these steps:

1.Make sure all the Virtualization stuff was enabled on the BIOS
2.Restart the Hyper-V services

if you still have the same error, download and install the Service Pack 1 RC.

Answer 2

I also found the same error as well on my hyper-v host.   I have sp1 and virtualization is enabled in the BIOS.

I had to reboot this hyper-v host in order to log onto one of the hyper-v machines.   What is the root cause of this error? 

The VHD is on a local drive and there are no hardware related errors.

Answer 3

Most newer servers have virtualization enabled out the box without any required BIOS changes.

If you have an ML350P Gen8 server you need to install SP1 (windows6.1-KB976932).  The older version of Hyper-V 2008 R2 gives an " <virtual machine> could not initialize" error.

Hope this helps.

Answer 4

In my case SP1 of Windows Server 2008 R2 did the trick. Server HP Proliant ML110 G7.

Answer 5

That was it!

Thank you Muawiyah!

SP1 solved the problem
