This report is quite low on details. My system is 6.3-RELEASE amd64. I have qemu-0.9.1_9 and kqemu-kmod-1.3.0.p11_9. Guest is 2.6.25.9-76.fc9.x86_64. kqemu.ko and aio.ko are loaded. Run like this is OK: qemu-system-x86_64 -no-kqemu -m 640 -hda box1.img -net nic -net tap Run like this - guest hangs during boot: qemu-system-x86_64 -m 640 -hda box1.img -net nic -net tap There are no messages on qemu output or in system log. qemu uses 100% CPU. Ctrl+Alt+2 works, I can execute commands in qemu console. BTW, info kqemu says "enabled for user code". Guest console messages: ... PCI: Using ACPI for IRQ routing PCI: If a device doesn't work, try "pci=routeirq".
