Hi Stefan,

which BIOS is selected by default? It's more a guess, there must be a 
change between 1.2.0 and 1.6.0 that prevents a simple Windows XP from 
booting completely, if the guest HDD image is placed on a SSD. On a 
rotating HDD (with the same commandline except the path to the image) it 
boots successfully. The only difference is the speed of the disk access.
I will try an alternative BIOS, maybe this fixes it, if not I will try to 
do some regression tests, first trying 1.4.0.

Best regards,

Erik
