I'm close to being out of ideas.

Did you build this model yourself? Does it have a pl011 UART at physical
address 0x1c090000?

Hi Ian. How can see the pl011 UART? In the window after I type "sgcanvas FVP_VE_Cortex-A15x1.sgproj"?

I built the model like this:

xiaoguang@dophine:~/ARM/FastModelsPortfolio_8.2/examples/FVP_VE/Build_Cortex-A15x1$ sgcanvas FVP_VE_Cortex-A15x1.sgproj

And then build.

The building log shows:

--------------------------------------------------------------------

Model Build process completed successfully.

--------------------------------------------------------------------

I can run a linux in this Fast Model following the instructions in this guide: www.virtualopensystems.com/media/kvm-resources/kvm-arm-guide.pdf

The command to run linux like:

$ model_shell ~/ARM/FastModelsPortfolio_8.2/examples/FVP_VE/Build_Cortex-A15x1/Linux64-Release-GCC-4.4/cadi_system_Linux64-Release-GCC-4.4.so -C motherboard.smsc_91c111.enabled=1 -C motherboard.hostbridge.userNetworking=1 -C cluster.cpu0.semihosting-cmd_line="--kernel linux/arch/arm/boot/zImage --dtb vexpress-v2p-ca15-tc1.dtb -- earlyprintk console=ttyAMA0 mem=2048M root=/dev/nfs nfsroot=192.158.1.15:/home/xiaoguang/nfsroot/ rw ip=dhcp" boot-wrapper/linux-system-semi.axf

So I'm wondering if I have to build a boot loader? Or if I have sth. wrong to build a correct xen image?

Next step would be to run the model in modeldebugger instead of
model_shell and see where it is going wrong.

I think I have to read the modeldebugger manual first. 

Ian.

Thanks!

Sincerely,

Xiaoguang
