Hello, after some time I tried again if there is any good change in KVM booting Windows 7. Still no luck. I did fresh install of Windows 7 (32 bit) into KVM virtual machine (qemu-kvm, i686 arch) on my Fedora 16 (x64) running on HP Pavilion dv7 (4GB RAM, intel i7 CPU). Installation went (slow but) fine. After that Windows refuse to boot and all I see is a cursor on top left corner. See attached log. First two boots are from installation, the last one is when Windows should boot to normal operation. According to the log, W7 was installed under qemu-kvm, i686 arch, so it should be able to run. I tried installing Windows XP and Fedora 16 (both 32bit versions, qemu-kvm, i686 arch). They both work fine. I searched other sites and found that there are other users experiencing the same problem. See http://www.linuxquestions.org/questions/slackware-14/qemu-says-my-cpu-is-too-old-897074/. I'm able to run W7 in VMWare Player with hw virtualization without problem and as others wrote (see link above) it's running fine in Virtual Box as well. So I'm affraid there's a problem in qemu-kvm. Please try to fix it. I (and i hope many other) would really appreciate it. I'd like to get rid of VMWare as it recompiles modules after each kernel update and when there are siginificant changes in kernel headers it won't compile (and run) at all. Martin E.
