Comment 11 for bug 666180

@Philippe Gauthier

I tried getting rid of libvirt and invoking qemu directly but that did not help.

All of these fail the same way:

qemu -M pc -hda /img/lenny-vol.img -m 1024 -cdrom /iso/debian-507-i386-netinst.iso -net nic,vlan=0 -net user,vlan=0,hostname=emu -monitor pty -boot d

qemu -M pc -hda /img/lenny-vol.img -m 1024 -cdrom /iso/debian-507-i386-netinst.iso -cpu qemu32 -net nic,vlan=0 -net user,vlan=0,hostname=emu -monitor pty -boot d

qemu -M pc -hda /img/lenny-vol.img -m 1024 -cdrom /iso/debian-507-i386-netinst.iso -enable-kvm -net nic,vlan=0 -net user,vlan=0,hostname=emu -monitor pty -boot d

qemu -M pc -hda /img/lenny-vol.img -m 1024 -cdrom /iso/debian-507-i386-netinst.iso -enable-kvm -cpu qemu32 -net nic,vlan=0 -net user,vlan=0,hostname=emu -monitor pty -boot d

Attempting to boot Debian 5 32-bit guest gets as far as
"Decompressing Linux... Parsing ELF... done."
"Booting the kernel"
Then nothing. The kvm process spins the CPU 100% on the host.
