The command I use is:

sudo ./arm-softmmu/qemu-system-arm -M realview-pbx-a9 -m 1024 -kernel
thekernel -serial telnet::4444,server -append "console=earlycon
console=ttyS0 console=ttyAMA0 earlyprintk root=/dev/nfs
nfsroot=10.1.1.1:/armroot rw
ip=10.1.1.2:10.1.1.1:10.1.1.1:255.255.255.0:armqemu nfsrootdebug "
-net nic -net tap,ifname=tap0,script=no,downscript=no

and then telnet to port 4444 to get the console.

(I'm using the linaro qemu tree).
