VirtualBox on Genode

[Yevgeny Lavrov]

Hello

I'm currently trying to reproduce VertualBox with Tinycore Linux running on
top of NOVA hypervisor scenario on x86-64 hardware.

The steps I've taken so far are:
1) ./tool/ports/prepare_ports for nova and virtualbox
2) ./tool/create_builddir nova_x86_64
3) uncommented REPOSITORIES += $(GENODE_DIR)/repos/libports line in
<Genode-dir>/build/nova_x86_64/etc/build.conf
4) Downloaded Tinycore Linux .iso image

Questions:
1) Where should I put Tinycore Linux .iso file? It says save it as
bin/test.iso in the similar thread "running VirtualBox on Genode" on Genode
mailing lists. Is it <Genode-dir>/build/nova_x86_64/bin directory that gets
created after executing make run/demo?
2) Where should I add "<config><image type="iso"
file="/iso/test.iso"/></config>" ?
3) Where to execute make run/virtualbox? I assume it's my build directory.
However, executing it in my build directory results in Error: no run script
for virtualbox.

Please advise
Thank you

Not needed, see below.

Yes, call in your build directory, <Genode-dir>/build/nova_x86_64,

make run/virtualbox

However, executing it in my build directory results in Error: no run script
for virtualbox.

The effectively used run script is located in
$(GENODE_DIR)/repos/ports/run/virtualbox.run, so you have to add also
the "ports" directory to your build.conf file.

So do the same as with "libports", in your words:

uncommented REPOSITORIES += $(GENODE_DIR)/repos/ports line in
<Genode-dir>/build/nova_x86_64/etc/build.conf


Cheers,

Alex.

Thank you for the advise, everything compiled w/o any problems. However,
while testing it via Qemu, I ran into the following issue: once Tinycore
Linux reaches "Booting the kernel" phase, it hangs, and the following msg
gets displayed on my terminal:

I've also attempted to create bootable USB from virtualbox.iso via dd.
While on boot, I got the following msg

HDD EBIOS
isolinux.bin missing or corrupt

Any suggestions on where something might have gone wrong?

Thank you

running Virtualbox inside Qemu is not supposed to work well.
Additionally the SVM (AMD virtualization extension) emulated by Qemu is
not tested nor maintained by us. So you should run it on native Intel
hardware.

Additionally, if your Linux distro with Genode is running as a VM this
also causes reliable trouble (e.g. Genode VM -> qemu ->
VirtualBox/Genode - Tinycore Linux)

I've also attempted to create bootable USB from virtualbox.iso via dd.
While on boot, I got the following msg
HDD EBIOS
isolinux.bin missing or corrupt

Just guessing:
- either the image got not correctly to the USB stick
- your BIOS/UEFI does not like your USB stick or has trouble in the USB
boot emulation

Try another USB stick or on another native machine or sometimes
switching the USB ports (on a USB 2 port instead of USB 3) may help.

I am working with Yevgeny on this part of the project and I am having the
same issue. I know that running it through the QEMU emulator probably
won't work so I used the virtualbox.iso image and put it onto my bootable
USB stick. This is the same stick that I have the Genode demo with a Nova
kernel running perfectly fine on, I have booted multiple machines with this
demo image, however the virtualbox ISO image boots, but does not load the
tinycore image properly - it hangs on booting to the VirtualBox machine in
the Genode environment.

can you please provide/look at the serial output of the native machine,
in order to get an idea of what went wrong. Without it will be hard to tell.

Neither of the two machines I have tried this on have a native serial
port. Will a USB to serial connection work or will I need to add the
dde_linux component for the USB drivers?

No, this is not going to work.

You may check whether the machines support Intel AMT in your UEFI/BIOS.
It provides a feature called SOL (SerialOverLan) with that you can route
the serial output to some other machine.

Otherwise you will need some PCI/Serial card for your desktop/server
machines or for notebooks there are mini PCIe cards if you have such a slot.
