[Qemu-arm] Suggested command-line for ARM

[G 3]

I tried making a suggested command-line section in your ARM wiki  
page, but my lack of experience with ARM prevents me from testing it.  
What do you think of this as the suggested command-line for qemu- 
system-aarch64:

qemu-system-aarch64 -m <memory size> -M <machine name> -drive  
if=none,file=<hard drive file name>,id=hd0 -device virtio-blk- 
device,drive=hd0 -netdev type=tap,id=net0 -device virtio-net- 
device,netdev=net0

If you know of a better one, please let me know.
