Perhaps trunk works

Hi, could someone of you test JNode trunk in VirtualBox? I remember we discovered a long time ago, that JNode crashes on VirtualBox, because it accesses some memory addresses that were too large for system ram.
A week ago or so we fixed a bug in our memory management that caused JNode to write beyond system RAM. So perhaps JNode trunk already runs on Virtual Box.

What setting are you using in VirtualBox? I've set the memory to 512M and left everything els set to the default. I got an exception in Main:75 but the first few lines scrolled off the screen. Now it seems to be hung looking for plugins.

Hi,

I saw this project and was interested enough to download and try it in a VM.

The first two options at boot (default and all plugins) both boot successfully to a usable prompt in VirtualBox for me.

JNode 0.2.6
Ubuntu 8.04.1 x64
VBox OSE 1.5.6
set with ~500MB RAM
16MB video
all other settings as default

One exception during boot;
Cannot start acpi
NPE @ 0FD2D40A

despite acpi being enabled in VBox

I appreciate this might not be trunk, but your current ISO download works. Once I get my env sorted I'll try Trunk.

It is encouraging news that JNode now works to some degree on VBox. Thanks for your investigations and report!

The fact that ACPI didn't work on VBox is not a surprise. JNode's ACPI drivers are not implemented yet, not even in SVN. However, it is worthwhile checking out and building JNode from SVN. There was an important fixes to a JNode stability issue recently, and we've made progress in other areas as well.

Please persevere with JNode on VBox and let us know if you find anything else noteworthy.

Well I built with build.sh cd-x86 and got an ISO 3x the size of the one I downloaded.

Boots in VBox(with default from grub at least), with the acpi exception and :
"Cannot start pci(0,2,0)
DriverException: grub haven't switched to graphic mode"

Gives me a usable prompt though.

Looks like it gives me a network, so i'll have a look at either the tcp logger or the kernel debugger and have a play to see what I can break Eye-wink
