running Virtualbox on Genode

Wed Sep 23 04:41:12 CEST 2015

Hi, Alex,

After a long break, I would like to update you on my recent work.
I've revisited the run script that you created for a USB boot-up.
It worked - previously it was a careless mistake on my part with the dd
command - use a wrong device name.

The USB boot-up could now boot-up partially but mainly on Acer hardware,
but not on Dell or HP hardware - the screen would hang on the Genode bootup.

For the Acer bootup, it was only partial - after the Windows 7 screen came
up, it seemed "hang" for very long. The mouse pointer can still movec
though.
I understand without serial port hardware, it is near to impossible to
troubleshoot. As such, I am thinking of purchasing a refurbished Lenovo
X201 - the same one that Norman is using.
I also tried using VMware Workstation and Virtualbox to boot up the USB
stick. I even swapped the Guest VMs between Ubuntu and Windows 7. All would
hang after Genode boots up.

Btw, is it necessary to stick to 32-bit versions of the Guest OSs ? I
notice the vbox_auto_win8 using the "assert_spec 64bit", does this meant
that this script is for 64-bit Guest OS.
Anyway, I would to consult you what are the main hardware features that are
required to be compatible to the Nova/Genode software ?

I would like to move on to a hard-disk based configuration in the long run.
I hope to be able to run two operating systems, Windows and a Linux on top
of Genode/Nova, both supporting Java applications. Can you recommend any
scripts or configuration steps that I can use to do such a setup. I am
trying using the vbox_auto_win7 and vbox_auto_win8 scripts.

Thanks.
