Re: [Xen-devel] Problems in running XenARM on Cortex-A15 Fast Models

[XiaoGuang Wang <xjtuwxg@xxxxxxxxx>]

Thanks Stefano,

I just cannot see the four x-term windows. And when I try to telnet port 5000, it will halt:

xiaoguang@dophine:~/works/arm/linux$ telnet localhost 5000

Trying 127.0.0.1...

Connected to localhost.

Escape character is '^]'.

I can run a linux kernel on this Fast Model with a x-term window appears. And I followed this manual: www.virtualopensystems.com/media/kvm-resources/kvm-arm-guide.pdf

So I don't know why I cannot bring up x-term windows when I start xen on fast models. Normally, will it start x-term windows if I do the command like: 

model_shell FastModels/FastModelsPortfolio_7.0/examples/RTSM_VE/Build_Cortex-A15x1/Linux64-Release-GCC-4.1/cadi_system_Linux64-Release-GCC-4.1.so xen.git/xen/xen.axp

Thanks!

Sincerely,

Xiaoguang

The command above should bring up four x-term windows.
Did you try to connect to port 5000 via telnet?

telnet 127.0.0.1 5000
