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).
