I have Kubuntu 11.10 Oneiric with standard 3.0.0-12-generic kernel on an AMD Phenom II X6 box. I've been running Windows 7 guest under qemu ....
$ /usr/bin/qemu-system-x86_64 -version QEMU emulator version 0.14.1 (qemu-kvm-0.14.1), Copyright (c) 2003-2008 Fabrice Bellard $ sudo /usr/bin/qemu-system-x86_64 -boot c -drive file=~/Win7.img,if=virtio -m 4096 -smp 1,cores-6 -net nic,vlan=0,macaddr=52:54:db:7f:0c:3d,model=virtio -net tap -vga cirrus -soundhw hda -cdrom /dev/sr0 This boots the Windows 7 client, no problems Then I installed qemu-0.15.1, compiled and installed from source and ran the same qemu startup command line with the new version $ /usr/local/bin/qemu-system-x86_64 -version QEMU emulator version 0.15.1, Copyright (c) 2003-2008 Fabrice Bellard $ sudo /usr/local/bin/qemu-system-x86_64 -boot c -drive file=~/Win7.img,if=virtio -m 4096 -smp 1,cores-6 -net nic,vlan=0,macaddr=52:54:db:7f:0c:3d,model=virtio -net tap -vga cirrus -soundhw hda -cdrom /dev/sr0 This results in Windows BSOD. I tried installing libvirt-bin_0.9.6~oneiric-2ubuntu5_amd64 to see if that would help, but it didn't. It's possible there's some prerequisite or compile option for the new version, not sure? Can someone tell me what's wrong and/or how to fix? Thx, Gus
