Genode/NOVA+Multiple VMMs Seoul / VBox

[Roger Ferreira]

Hi, 
By reading Documentation/init.txt I realized I was missing the root=/dev/ram0.
That solved the problem.
In the original run script example, it is there in the cmdline.
I am quite sure I had tested before with that boot option.
The only difference is that I managed to reduce the image now down to 89M.
Nevertheless, I appreciate the help and apologize for any inconvenience. 

Regards,
           Roger

Initrd images are usually (if not always) cpio archives without gzip compression.

Hi,
I built a 89M image and I am using Tinycore 6.3 vmlinuz.
I get the following error on QEMU window:> sudo qemu-system-i386 -kernel vmlinuz -append "quiet" -initrd tc-dds.gzFailed to execute /init (error -28)Kernel panic - not syncing: No working init found.
On Genode with QEMU, using the seoul-wm-cli.run script adapted to the new kernel / initrd images everything works fine:genode/build/nova_x86_32$ make run/seoul-wm-cli_tc
until I launch the VM:> start seoul

The same error saw on QEMU alone appears in the cli_monitor->seoul VM window.
I will try to build the kernel.
Thanks.
