Virtual Box Guest Additions
« on: August 20, 2009, 10:14:24 PM »
Seeing as how quite a few people are using TC/MC inside VBox, including myself, I have made a script to automate the acquisition of the Guest Additions from the running VM.  This script has been testing using VBox 3.0.4 and TC/MC 2.2 with full Xorg.  I recommend booting with bootcodes 'base norestore nolocal' to create the extension which you can then copy to your persistent tce/directory.  This build process requires the compile environment, Xorg with dependencies, Xorg-devs with dependencies, linux-kernel-headers, and usbutils and uses almost 300MB of memory/swap to complete.  The resulting extension will only be 1.5MB though.  I will include a working xorg.conf.vbox that will get renamed and moved into /etc/X11 by the script. The script will complain if you don't download or create the xorg.conf.vbox.  

I will keep the script posted here and an attachment updated as suggestions, request, or improvements are made

I apologize for my newbie question, but could you explain to me why you used "getbasefile"
and the number "1"?
I am learning shell script.

It's to get the "example" part out of "example.tce"
See /etc/init.d/tc-functions for the function

You could also set repository path to mirror at top of script:

Code: [Select]
MIRROR="$(awk '/Mirror/ {print $2}' /opt/.tcrc)"

Thanks for the suggestion.  Implemented in the checkformicro() function.  For the downloading of the normal extensions, tce-wget (through tce-load) is already using the mirror specified in /opt/.tcrc.  Keep in mind that if you are attempting to run this in MC with a custom repository, it will need to have a similar directory structure as the official repo for the releases and core elements.  Although as stated in first post, it is strongly recommended that this be run after rebooting and using bootcodes "base norestore nolocal" which would use the official repo. This is recommended to avoid adding the compile environment and Xorg-devs to your persistent tce/ directory.

Good piece of work this script making the guest additions of virtualBox available on TC.

Usually the official edition from Sun will be used as virtualBox:
http://dlc.sun.com/virtualbox/vboxdownload.html

This PUEL licensed edition is free for any personal (even commercial) use:
http://www.virtualbox.org/wiki/VirtualBox_PUEL

But it is't not free distributable, with the consequence that this version can't be used to build a stand alone extension.

For free distribution you have to use the GNU licensed open source version which has got nearly aquivalent content. The main difference is that the free version hasn't got USB passing through capability. For details see:
http://www.virtualbox.org/wiki/Editions

Anyway the free version has got guest additions too. The only limitation is that the free versions mustn't be called 'Virtual Box', as this name ist trademarked for Sun:
http://forums.virtualbox.org/viewtopic.php?f=10&t=11951

Even if both versions are nearly equivalent, details and download sources for the free version are pretty diffcult to find. Following a collection of the links I stumbled over:

Snapshot and code repository offerded by Sun (see bottom of the page):
http://www.virtualbox.org/wiki/Downloads

The virtualBox guest additions installer project on Google Code:
http://code.google.com/p/virtual-box-windows-guest-additions-installer/
http://code.google.com/p/virtual-box-windows-guest-additions-installer/wiki/MainPage

There is a German Debian site with some more links
http://packages.debian.org/lenny/virtualbox-ose-guest-source

Inclusive a download link for the OSE version guest additions:
http://packages.debian.org/lenny/all/virtualbox-ose-guest-source/download

Finally there is a Virtual Box OSE Debian install howto here:

It may take a little time, but I am working on getting VBox-OSE compiled on TC and then grabbing the Guest Additions out of that which should be free distributable.

See portable-virtualbox for a solution... here the portable wrapper for VBox downloads and installs *to itself* the VirtualBox runnable from Sun. There is a mandatory "not an official version ... not sun supported..." splash screen.

To sum up:
    one downloads and runs portable installer,
    it downloads sun vbox installer & extracts files from it & deletes it.

http://www.virtualbox.org/wiki/Editions

If you are running VBox from linux you don't need "USB passing through" as one can access these from the host filesystem.

Assuming your guest additions are in place mount a folder on your host OS.
  [# mount.vboxsf name mountpoint ] Where name is a name of a VBox shared folder on your host OS and mountpoint is a folder on your guest OS.

From the host OS open a terminal in the name folder and make a symbolic link to root.
  [# ln -s / hostroot ] Where / is the root and hostroot is a name you like for the link.

Now you can open emelfm, for example, and navigate (on Debian, for example) to USB.
 [ mountpoint/hostroot/media/disk ]

If you are running msWin this is not as easy, but links can be made if you go get the tools.or are running a suitable version. Info available on google, or I can look about for more if anyone needs.

OK. nuff for today on this old topic.

Thanks for the guest additions for TC Kingdomcome!
