Hello,
I am trying get Virtualbox using rump_fs in a qemu environment.
I am using a modified virtualbox.run script called vb_ide.run. Eventually Virtualbox is started as follows:
qemu-system-x86_64 -no-kvm -cpu core2duo -m 512 -boot order=d, -hda /GV/QV.img -serial mon:stdio -cdrom var/run/vb-ide.iso
Device -hda contains an ext2 filesystem upon which an original VirtualBox VMs directory environment is installed.
The following is part of the init script that is used.
<start name="atapi_drv"> <resource name="RAM" quantum="5M"/> <provides><service name="Block"/></provides> <config ata="yes"/> </start>
<start name="rump_fs" priority="-1"> <resource name="RAM" quantum="32M" /> <provides><service name="File_system"/></provides> <config fs="ext2fs"><policy label="" root="/" writeable="yes"/></config> </start>
<start name="virtualbox" priority="-2"> <resource name="RAM" quantum="750M"/> <config vbox_file="w7.vbox" vm_name="w7"> <libc stdout="/dev/log" stderr="/dev/log"> <vfs> <dir name="dev"> <log/> </dir> </vfs> </libc> </config> </start>
This part of the script and a similar qemu invocation have been used in a variation of the rump_ext2 script as well and works fine. The NOVA hypervisor is booted from -cdrom the programs are loaded from -cdrom as well. The test program issues filesystem operation resulting in manipulations of the filesystem on device -hda.
When stating Virtualbox however, is does not work. Everything starts fine, however, virtualbox does not seem to use rump_fs (I have placed a PWRN message in the rump_fs server code that did not show up). It terminates because it cannot find w7.vbox.

What I do not understand is, how one can tell/direct Virtualbox to use a particular device or filesystem. Can somebody explain this ?

you need to add an '<fs />' tag to the VFS configuration to integrate the file system provided by the 'File_system' service of 'rump_fs'.

Hello Christian,
thanks.
I have added <fs/> to the vfs config section of virtualbox. But now the system hangs and has to be canceled. No messages from virtualbox either.

Hello Christian,
here is the build script. I have done a make clean before to get rid of any "dirt". I should mention that two patches have been installed to rump_fs as suggested by Josef to improve sync management:
https://github.com/cnuke/genode/commit/5ba470b6b and another patch to provide sync() support to rump_fs.

Hello Christian,
I found a possible cause, it seems that the pci_drv and and apci_drv collide. By disabling append_if statements I prevented the apci_driver to be loaded and started.
I am getting much farther now, but I don't understand the following:
[init -> virtualbox] Log created: 2015-02-24T01:07:15.000000000Z [init -> virtualbox] main Executable: /virtualbox [init -> virtualbox] SystemProperties : Cannot determine default Guest Additions ISO location.

Expect: 'interact' received 'strg+c' and was cancelled adrian@...269...:~/genode-14.11/fs.build$
Why is VirtualBox complaining about the w7.vbox file that it is already there? I want VirtualBox to use this file and its vdi companion.

Hello Adrian,
I could not reproduce the same problem you reported, but found two other problems when trying to run VirtualBox in Qemu:
First, 'atapi_drv' does not run well on newer Qemu versions (I used Qemu 2.2.0), so I changed your run script to use the 'ahci' driver instead (see attachment).
Then I tried to run TinyCore Linux in the VM (with both the .vbox and the .iso file in the root directory of the ext2 image) and when the Linux kernel started to boot, VirtualBox reported 'invalid gueststate' errors and the kernel boot process never finished.
So, even if you can find out why your VirtualBox complains about the 'w7.vbox' file, I would not have too high hopes of getting your VM running in VirtualBox on Qemu (or with AMD SVM hardware virtualization in general) without some prior work on the VirtualBox port. So far we have used and tested VirtualBox mainly on Intel hardware. Would that be an option for you?
Regards, Christian
Hello Christian,
I have been running Nova 64 bit on a AMD Phenom machine and am using qemu version 1.0.
The problem symptoms varied from 'vbox file already existing' to not starting virtualbox at all. I decided to switch to Nova 32 bit. Now the symptoms are stable, I am getting 'vbox file already exising' every time now.
I went through the code of genode-14.11/repos/ports/src/virtualbox/frontend/main.cc, which to me seems to be the driver of VirtualBox proper.
At around line 106 I found rc = machine->init(virtualbox, vm_name, *machine_config); This call is unsuccessful and also generates the "Machine : Machine settings file '/VirtualBox VMs/w7/w7.vbox' already exists" message. I have located the the VirtualBox file where this message is emanating from, it is MachineImpl.cpp, which can be found in genode-14.11/contrib/virtualbox-fd1a0bb3692bfb4448f3b3f8978fc1c5d037e2c4/src/app/virtualbox/src/VBox/Main/src-server.
This is the function that is called at around line 502:
/** * Initializes a new instance from a machine config that is already in memory * (import OVF case). Since we are importing, the UUID in the machine * config is ignored and we always generate a fresh one. * * @param strName Name for the new machine; this overrides what is specified in config and is used * for the settings file as well. * @param config Machine configuration loaded and parsed from XML. * * @return Success indicator. if not S_OK, the machine object is invalid */
HRESULT Machine::init(VirtualBox *aParent, const Utf8Str &strName, const settings::MachineConfigFile &config)
In here, Machine::tryCreateMachineConfigFile() is called (at 534). This call finds out that the vbox file already exists and terminates VirtualBox.
I have tried to call Machine::initFromSettings() instaed in main.cc, but that causes a lot more error messages for which I am lacking detailed knowledge about the innards of VirtualBox.
Up to here, I don't think qemu or atapi_drv are to blame for this problem, the call to Machine::init() looks to be the problem.
So, how exactly did genode.org succeed in executing Windows 7 with VirtualBox on Nova using genode-14.11 ?

Then I tried to run TinyCore Linux in the VM (with both the .vbox and the .iso file in the root directory of the ext2 image) and when the Linux kernel started to boot, VirtualBox reported 'invalid gueststate' errors and the kernel boot process never finished.
So, even if you can find out why your VirtualBox complains about the 'w7.vbox' file, I would not have too high hopes of getting your VM running in VirtualBox on Qemu (or with AMD SVM hardware virtualization in general) without some prior work on the VirtualBox port. So far we have used and tested VirtualBox mainly on Intel hardware. Would that be an option for you?

Hello Adrian,
I could reproduce your problem now. It occurred when I stored the 'w7.vbox' file in the '/VirtualBox VMs/w7/' directory. Before, I had it stored in the root directory only and the problem did not occur. For running Windows 7 with VirtualBox on Nova we're using the 'virtualbox_auto_disk.run' script, which loads the '.vbox' file from the ROM service.

Hello Christian,
I have been off-line for a while, but want to come back to our conversation. Meanwhile, I was able to verify that the problem also exits in 15.02.
I just wonder what will be done to fix this. Is there a way to open problem-ticket for this problem ? Or, is there an explanation as to what the problem is ?
As to 'virtualbox_auto_disk.run', I am unable to execute this run-script. I get the message 'Run script does not support Qemu.'. Could you explain how this script should be executed ?
Regards, Adrian

you can create an issue at https://github.com/genodelabs/genode/issues
There's no explanation yet, but as a temporary workaround you can move the .vbox file into the root directory or load it from a ROM service.
As to 'virtualbox_auto_disk.run', I am unable to execute this run-script. I get the message 'Run script does not support Qemu.'. Could you explain how this script should be executed ?
A simple way to use the script is with the following run tool configuration in 'build/nova_x86_64/etc/build.conf' (latest Genode release):
RUN_OPT = --include boot_dir/nova \ --include image/iso
With this configuration, 'make run/vbox_auto_win7' will create an ISO image in the 'var/run' directory, which you could write on a USB stick (using 'dd') and boot from it on real hardware.
The script provides VirtualBox with the 'vm_win7.vbox' file, which needs to get adapted to the actual VDI files to be used. The 'overlay.vdi' file can be created like this:
- $ VboxManage showhdinfo win7.vdi - remember the 'Capacity' value - $ VboxManage createhd --filename overlay_win7.vdi --size [Capacity value] --format vdi
Also, the UUIDs in the 'vm_win7.vbox' file need to get replaced by the real UUIDs of the VDI files (also shown by 'VBoxManage showhdinfo').
The VDI files are loaded from an 'ext2' file system on the fourth primary partition of the hard disk. The partition number can be changed in 'virtualbox_auto.inc'.
Having a serial port on the target machine is highly recommended to know what the problem could be if it doesn't work right away.
