virtualized SBS 2011 hangs during Migration

Good morning,

I am trying to run a migration to SBS2011 in a ESXi 5.0 environment.
The SBS2003 I am migrating from is a VM on the same host.  

I prepared the SBS2003 for migration and created the answerfile which is located on a physical USB-stick made available to the new VM.
After that I booted the new VM the DVD located in the host's drive, started the installation with choice of language, accepting the EULA, choosing the partition.  The installation files were extracted and transferred.  The VP rebooted, and hangs from there on on "finalizing installation" or whatever the exact wording in English might be (I am installing German language version).

It's the second time with a new answerfile that I have done this.  The new VM is at 100% CPU load (it has one vitrual CPU).  RAM usage is only 491MB out of the 12GB available to this VM.

Any ideas?

RAM usage is oscillating between 128MB and 512MB by the way.  That's the only sign of life.  Last time the machine hung like this for more than a day before I put it out of it's misery.

How long did you wait?

I would allocate at least 2 vCPU, 8GB RAM, and repeat the installation.

What is the underlying ESX datastore?

and there are No Snapshots allocated to the VM, e.g. VM is not in snapshot mode or running on a snapshot?

I waited longer than a day.

12GB are in place, I added a second CPU.

The unterlying datastore is a RAID5 consisting of 6x 600GB SAS 15.000 U/min local discs.

Snapshots are not active on either VM.

Rerunning Setup now.
Apparently the domain on the source server was not yet altered.  The host does not appear under computers or domain controllers.

The cause of the issue was a not correctly prepared source DC.  There were AD-Issues that prevented ADprep from succeding.  Even though the mentioning of the problem was very brief in adprep32.exe / forestprep and the process finished saying it was successful, it really was not.  
After clearing that, installation went as it should.

Thank you everybody for your help.
