After adding earlyprintk, there's no any console output. Should I do some specific config when I make menuconfig? My configure file is downloaded from http://www.virtualopensystems.com/media/kvm-resources/host-config as the guide told me. The same, I'm not sure whether I should modify device tree file after clone it from git repository.

try adding earlyprintk to the kernel command line and see if you get
any console output.
if not, I would double-check the device tree file and the kernel config.

Hi, everyone.
I tried to install the latest kvm on arm on arm simulator. After following
the Development guide from http://systems.cs.columbia.edu/projects/kvm-arm/,
I stuck in the step named "Testing the host system".
When I started the simulator and telneted to localhost:5000, there's no
output from the serial port.
My Host: Debian6.0 x86_64
The simulator's output is listed bellow:
---------------------------
model_shell
~/ARM/FastModelsPortfolio_7.1/examples/RTSM_VE/Build_Cortex-A15x1/Linux-Debug-GCC-4.4/cadi_system_Linux-Debug-GCC-4.4.so

-----------------------------
BTW, the linux kernel is cloned from columbia repository, not virtual open
system. It would be nice if you have some idea to fix this problem. I'm glad
to receive your response. Thanks.
