HI, Jordan: By using the latest master of qemu, after booting the vnc view will continue to be just black, and the os cannot be start. After bisect, I found the problem was introduced by the commit: 235e8982ad393e5611cb892df54881c872eea9e1 (kvm: support using KVM_MEM_READONLY flag for regions). There are plenty of medications in this commit, so I report this problem to you. The running environment:
Qemu: 4eda32f588086b6cd0ec2be6a7a6c131f8c2b427 Host: Fedora 18, kernel: 3.8.1-201.fc18.x86_64 Boot Cmd: ./x86_64-softmmu/qemu-system-x86_64 -name ovirt -M pc-0.15 -m 1024 -enable-kvm -boot d \ -drive file=/pkgs/imgs/win7.qcow2,format=qcow2,id=drive0,if=none \ -device ide-hd,drive=drive0,id=disk0 \ -vnc 186.100.8.144:0 -monitor stdio \ -net tap,ifname=tap0,downscript=no -net nic I can provide more information if need. ---------- Leiqzhang Best Regards
