This is the command line I use to start qemu directly:

qemu-system-arm -M versatileab -m 256 \
    -kernel vmlinuz-2.6.32-5-versatile \
    -initrd initrd.img-2.6.32-5-versatile \
    -hda "debian_squeeze_armel_standard.qcow2" -boot order=c \
    -netdev tap,id=hostnet0,ifname=tap72,script=/home/kvm/armel/qemu-ifup \
    -device rtl8139,netdev=hostnet0,id=net0,mac=52:54:00:00:03:72 \
    -nographic -serial telnet::4000,server,nowait,nodelay \
    -append "root=/dev/sda1 console=ttyAMA0"


Adding the -nodefaults I had to use this command line (not 
exactly equivalent and not perfectly streamlined, but it starts):

/usr/bin/qemu-system-arm -M versatileab -m 256 \
    -smp 1,sockets=1,cores=1,threads=1 \
    -name armel -uuid bf9adc6c-f05c-2698-1cf0-278fd86dc19a \
    -nographic -no-user-config -nodefaults \
    -rtc base=utc -no-shutdown \
    -kernel /home/kvm/armel/vmlinuz-2.6.32-5-versatile \
    -initrd /home/kvm/armel/initrd.img-2.6.32-5-versatile \
    -append "root=/dev/sda1 console=ttyAMA0" \
    -device piix3-usb-uhci,id=usb,bus=pci,addr=0x1.0x2 \
    -device pl011 \
    -drive file=/home/kvm/armel/debian_squeeze_armel_standard.qcow2,if=scsi \
    -device lsi \
    -boot order=c \
    -netdev tap,id=hostnet0,ifname=tap72,script=/home/kvm/armel/qemu-ifup \
    -device rtl8139,netdev=hostnet0,id=net0,mac=52:54:00:00:03:72 \
    -serial telnet::4000,server,nowait,nodelay

I attach the virsh capabilities and the machine xml (which is not 
functional).
