Re: [XenARM] Xen on Goldfish Android emulator

Thanks. You are right, with some minor tweaks on the qemu Makefile to turn off mmx on a Ubuntu 10.04 x86 system, it compiled and booted.

It only worked for me when I ran it on a 32-bit system.

Anna, did you ever get past the core dump? I am having the same issues.

I build per the instructions and added the kernel variable to the command prompt, but I also get a core dump. I tried changing the Config.mk in the mini-os to a goldfish architecture rather than verstale and that has no effect. 

Anyone have any suggestions?

Dear Anna Fischer,

Three files named as system.img, userdata.img and ramdisk.img are the android

file system images. The android emulator requires these files, and the modification of

these files may not be needed in most cases.

The kernel-qemu is a default kernel image name.

To specify different kernel(hypervisor) image to be run, use "-kernel <file name>" flag.

 

In addition to, the dom0 and the domu kernel image should be supplied to the android emulator for correct boot strapping.

I am trying to get the Xen-on-ARM port to run on the Goldfish Android
emulator. I have downloaded all the code from here:
http://wiki.xensource.com/xenwiki/XenARM?action="">

Xen builds fine, the emulator builds fine, and mini-OS builds fine as
well.

However, when I try to run the emulator I get a segmentation fault. I
don't get any more specific error messages.

android-emulator-xen_arm# ./run.sh
guest0 - mini-os.elf
guest1 - mini-os.elf
Waiting gdb connection on port 1234
./run.sh: line 1: 31813 Segmentation fault      ./emulator -guest0
0x01c00000 mini-os.elf -guest1 0x02c00000 mini-os.elf -show-kernel
-system ./images -shell -qemu -s

My question is now, the files in the image/ folder, do they not have to
be changed at all? In your documentation you describe that xen-bin needs
to be copied in there (as qemu-kernel), but that file is never used in
any of your scripts? Also, the Dom0 kernel is not copied into that
folder at all according to your documentation, but does it not need to
be used when booting in the emulator?

I have followed the documentation here:
http://wiki.xensource.com/xenwiki/XenARM?action="">

I think something in your documentation is missing, it does not describe
how the system images are loaded into the emulator.

Can you help me with this?

Thanks,
Anna
