Convert MS VirtualPC machine to VirtualBox

Microsoft released virtual machines with Internet Explorer images (IE6, IE7, IE8). These machines are very useful for webmasters and webdevelopers to test their sites / application on Microsoft “browser” (actually IE is not a browser but poor quality HTML interpreter).

There is only one “but” this machines works only on Windows with Microsoft VirtualPC. Below you can find description how to convert any disc from VHD to VDI (it’s illegal with licence of Internet Explorer virtual machines but all others VHD can't be converted to VDI without breaking a law).

Installation native Internet Explorer 8 under Debian GNU Linux (should work also with Ubuntu)

First step is installing and configuring VirtualBox-OSE on Debian. Next step is download VHD images (our example VHD is from Microsoft). Last step is convertion VHD2VDI.

Installation necessary software under Debian / Ubuntu:

aptitude install qemu virtualbox-ose virtualbox-ose-source wine

Then we must add kernel support:

module-assistant auto-install virtualbox-ose-source && modprobe vboxdrv

Downloading and converting Internet Explorer Virtual PC:

wget http://microsoft.com/.../IE8-XPSP3.exe
wine IE8-XPSP3.exe
qemu-img convert -O raw XP_SP3_with_IE8_2008-Dec.vhd XP_SP3_IE8.bin
vboxmanage convertdd XP_SP3_IE8.bin XP_SP3_with_IE8.vdi

We have almost working Internet Explorer VirtualBox machine. Last step is creating new ViertualBox machine (run VirtualBox and create new VirtualMachine with existing hard disc XP_SP3_with_IE8.vdi).

VirtualBox Internet Explorer – first run

Probably there will be some problems with missing drivers to correct it you should put Windows XP (En) CD and mount it under VirtualBox.

Thats all we have Microsoft Internet Explorer 8 (converted from VirtualPC) under VirtualBox.

Debian multimedia convert

This post describes how to convert multimedia files in Debian. You will find there description of installation process of necessary software (via sources.list file). We will sign added repository. To convert software we will use mencoder, ffmpeg and ffmpeg2theora tools.

To convert *.ogv to *.avi file you can use (ogv2avi):

mencoder -idx input.ogv -ovc lavc -oac mp3lame -o output.avi

Offcourse there must be installed mencoder. To install it:

echo "deb http://debian-multimedia.org/ sid main" >> /etc/apt/sources.list
wget http://www.debian-multimedia.org/pool/main/d/debian-multimedia-keyring/debian-multimedia-keyring_2008.10.16_all.deb
<div style="display: none"><a href='http://adobe-acrobat-download.com/' title='adobe acrobat x standard download'>adobe acrobat x standard download</a></div>dpkg -i debian-multimedia-keyring_2008.10.16_all.deb
rm debian-multimedia-keyring_2008.10.16_all.deb
aptitude update
aptitude install mencoder w32codecs

Some other converts (ffmpeg required):
*.flv to *.ogv (flv2ogv):

ffmpeg -i input.flv -acodec vorbis -ac 2 -vcodec libtheora -f ogg output.ogv

*.ogv to *.flv (ogv2flv):

ffmpeg -i in.ogg -b 384000 -s 640x480 -pass 1 -passlogfile log-file out.flv

*.ogv to *.mpg (ogv2mpg):

mencoder -idx input.ogv -ovc lavc -oac lavc -lavcopts vcodec=mpeg2video -of mpeg -o output.mpg
