Hi, Above steps given by Peter Chubb worked fine. I was able to get the output through serial port. But it executes the test suite and then stops. How can I get a shell prompt so that I can test the kernel for virtualization? My question may be completely wrong here but I'm new to this field. How can one use seL4 kernel to install virtual OS on top of it on x86 architecture? On Fri, Sep 5, 2014 at 5:10 AM, Peter Chubb wrote:

If you have built a seL4-based systemaccording to the instructions, the kernel and root server are in .../images/ They have different names according to what you've built.

For example, sel4test names the root server sel4test-driver-image-ia32-pc99 and the kernel kernel-ia32-pc99

I generally use syslinux to create a bootable USB stick, as the grub on my system wants to use EFI.

Like this, assuming your flash drive is at /dev/sdb with a FAT partition at /dev/sdb1:

install-mbr /dev/sdb syslinux --install /dev/sdb1 mount /dev/sdb1 /mnt cp images/sel4test-driver-image-ia32-pc99 /mnt/rootserver cp images/kernel-ia32-pc99 /mnt/sel4kernel cat > /mnt/syslinux.cfg <

use fdisk to make sure the first partition is bootable.

And you're done. Output will come on the serial port

Hope this helps. -- Dr Peter Chubb peter.chubb AT nicta.com.au http://www.ssrg.nicta.com.au Software Systems Research Group/NICTA

Hi, I am at Tongji University (China, http://www.tongji.edu.cn/english/ ), I want to build a Fault Tolerant Operating System for high speed railway. The seL4 is just a micro-kernel operating system, there is still no centre-service to let it work as a PC operating system, and it still can’t work as a virtual-machine, such as VirtualBox. There are a lot of works should be done before seL4 used as a really operating system.

Hi Peter, Your method is great. But I meet some problems. The bootable usb works very well on laptop. But when I move to a large machine which has two sockets, and each socket has six cores(my laptop only has 2 cores), syslinux can only print out something like "loading kernel is ok", and after some seconds, the machine reboot. It just keeps rebooting again and again. I do not know why it is. Is it possible for syslinyx to reboot the machine if I have some incorrect configuration of it? Is it possible for the sel4 kernel to reboot the machine if it detects some error or I do not config sel4 correctly? Does it need some special configuration for sel4 with a machine which has mult-sockets multi-cores? If so, how to do it? Could anyone give me some hints? Thank you very much.
