Some more information: I have upgraded to Kernel 3.12.6, and the problem is still there. However, when starting the same machine manually with simpler command line like qemu-kvm -cpu Nehalem -machine accel=kvm -m 4G /virtual_disks/win7_master.img qemu will not crash, but Windows (in the guest machine) will still fail to boot up all the way. It bluescreens once, restarts, then manages to start some graphical computer repair wizard which will run for a long time and then display a message saying it could not repair the computer, offering to send the problem report to Microsoft... It didn't show an error message that would tell me what is actually wrong, though.
