After installing the VirtualBox OSE on the Ubuntu 8.04, I installed Windows xp.
There is a keyboard issue.

It can be solved by adding the follwoing lines in the /usr/bin/VBoxManage.


GTK_IM_MODULE=none
QT_IM_MODULE=none
XMODIFIERS=none

Sometime I cannot empty out my deleted files in the trash due to the permissions.

Then go to .local/share/Trash , delete all files and directories with sudo or su permission.

umount: /media/usb-vfat: device is busy

# fuser -a /media/usb-vfat/
/media/usb-vfat/:    12832c 12833c
 -a        display unused files too

# fuser -k /media/usb-vfat/
/media/usb-vfat/:    12832c 12833c
-k        kill processes accessing the named file

or

check alll processes using "usb-atom"

# /sbin/fuser -m /media/usb-atom/
/media/usb-atom/:     5098c

# ps aux |grep 5098
xxxx     5098  0.0  0.0   5744  1896 ?        Ts   08:59   0:00 -csh

# kill -9 5098

# umount /media/usb-vfat/


* note that /sbin/fuser is for RHEL5.3
