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 126.96.36.199-76.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:
