Distro: - Ubuntu 8.04 CPU: - Intel(R) Core(TM)2 Duo CPU T7700 @ 2.40GHz qemu-system-x86_64: - QEMU PC emulator version 0.9.1 (kvm-84), (I Built locally) Bug: I had installed distro kvm (for Ubuntu 8.04) and created a guest Fedora10 image. I eventually uninstalled the distro kvm and built kvm-84 myself. I have been using this kvm-84 and the Fedora10.img for a while with libvirt (0.6.0) which again, I built locally. Today when I try to create a new Fedora10 guest image: $ qemu-img create -f qcow2 Fedora10.img 10G $ sudo qemu-system-x86_64 -hda Fedora10.img -m 1024 -boot d \ -cdrom Fedora-10-i386-DVD.iso Segmentation fault /var/log/messages shows: kernel: [ 193.077299] qemu-system-x86[7810]: segfault at 000001a0 eip b7cd72f5 esp bfd5e0cc error 4 If I remove the 'sudo' it gives "Permission denied" on /dev/kvm, but the same command works fine (in slow motion). Pls let me know if I can collect other debug info.
