Hi, I almost identical problem so i post here my comment. I'm trying to use qemu 1.1.0 to run some vm on a RHEL5.8 _without_ kvm accelaration (the host have 24 cpu core, I can't install kvm module on the server, policy problem, but I still want to exploit some cpu power).
I compiled qemu 1.1.0 with default options (just --prefix=...) and it works with linux guests (very few try, ttylinux, Oracle Linux, all seems fine.) but I'm not able to start any Microsoft Windows guest (tried installed guest from virtualbox and iso installation cd). Here the systems I tried: Windows 2008 R2 x64: qemu-system-x86_64 -m 2048 -cdrom win2008r2x64.iso -hda test.win2008.qcow2 blue screen: *** STOP: 0x0000005D (0x00000000078BFBF9,0x0000000000000000,0x0000000000000000,0x0000000000000000) Windows 8 ConsumerPreview 32bit: qemu-system-i386 -m 2048 -cdrom Windows8-ConsumerPreview-32bit-English.iso -hda test.win8-32.qcow2 black screen: Your computer needs to restart.
