Backup / Increase the Guest OS Drive on VirtualBox

Tried to search online for a way to increase the size of a vdi image, and there was no solution available online to do so.
I had windows XP installed on a virtual machine for mail, and testing purposes on the most hated IE6, and the drive ran out of a space, no solution or work around helped me increase it, all the solutions to modify the partition table, etc didn’t work for me.
Here is the simple steps i followed :

  • Add Another Disk Drive to the Guest OS
  • Backup the Guest Operating system drive using Norton Ghost to the newly added drive.
  • Copy the backup to a DVD image (I had to move it to the host drive first)
  • Make a new Virtual Machine with the new size you want.
  • Boot the new machine using Norton Ghost drive, and attach the DVD image with the created backup.
  • Restore the backup from the DVD created using Norton Ghost.
  • Restart the machine and you should have a working.
  • Delete the created DVD image, the extra hard disk, and the old machine.

If you have a shorter solution, please share :)

Installing Zend Server on Ubuntu 10.04

I have been having issues trying to install Zend Server on Ubuntu 10.04 following the steps here http://files.zend.com/help/Zend-Server-5-Community-Edition/zend-server.htm#deb_installation.htm
the problem was because there is a missing dependency for the “libmysqlclient15off” MySQL client library

to solve this, I had to install “libmysqlclient15off” from here (select the one that matches your architecture)

http://archive.ubuntu.com/ubuntu/pool/universe/m/mysql-dfsg-5.0/

Then install it using the command line :

dpkg -i libmysqlclient15off_5.1.30really5.0.83-0ubuntu3_i386.deb

after that running the installation for Zend server from through repositories, will work with no interruptions.

Compress and Split large files under Linux

One of the common problems i used to face is transferring large files from Linux through mediums that doesn’t support large files, especially when it comes to more than 100 GB files, usually that is a virtual machine hard disk, or backup file.

To compress and split files under linux, this command can be used:

tar -cvj large-file.dvi | split -b 1000m -d - "small-files.tar.bz."

This command will compress and split the “large-file.dvi” to many files with size 1000mb for each, giving it the name “small-files.tar.bz.0, small-files.tar.bz.1, etc….”

To join the files together again, this command can be used:

cat small-files.tar.bz.* > large-file.tar.bz

and to extract the output file :

tar -xvj large-file.tar.bz
