I am trying to convert several VMware images towards Virtualbox images. I have succesfully been able to convert my Windows Server 2003 image, but I haven't been able to convert any Windows Server 2008 image.

I found 2 solutions on the internet.

One solution involves creating a new image giving the previous .vmdk as hard disk. When I try to startup the image, I get a blue screen during booting. (I also tried to delete VMware tools before importing the image, which didn't work).

The other solution involved exporting the image to an OVF image and then open it with Virtualbox. This image got stuck in the "windows is loading" screen.

Host OS: Windows 7 Enterprise Guest OS: Windows Server 2008

Stick with the first solution.

The HDD types need to match. If you were using SCSI on VMware you need to be using SCSI in VirtualBox. In rare occasions you actually need to experiment a bit with disk types (ie a SCSI VMware disk will work properly only on SATA controler in VirtualBox, go figure).

Another thing that causes instability and bootup problems are IO APIC and PAE/Nx settings under System. Experiment with those. It can take couple of boots till you get it right but so far I've never had a physical (or virtual) machine I couldn't get onto VirtualBox using VMware tools.

The virtual machine now boots up until "Loaded: \Windows\system32\driver\crcdisk.sys" (booting in safe mode). Does this mean I can presume the harddiks type is correct? – Bart Burg May 2 '12 at 12:27
Thank you, this did work! After a long boot, it worked. After the first boot, the boot time is normal. – Bart Burg May 8 '12 at 11:09

You need to delete the Disk controller, Add new SAS Controller and attach to it the Disk Image. It will work! ;)

Thanks for the answer, it didn't work though. I still get stuck at "Loaded: \Windows\system32\driver\crcdisk.sys" (booting in safe mode) when booting. – Bart Burg May 2 '12 at 12:29
SAS Controller worked for me when migrating Win2008r2 64bit. No other changes required. – Aoi Karasu Jun 27 '12 at 9:44
