a link to instruction and solutions to few problems (screen resolution, fingerprint reader, shared folders and xorg.conf)
I mainly followed this guide: http://chaits.accosted.net/?p=54
EDIT: i had to use “./VBoxManage.exe internalcommands createrawvmdk -filename C:\path\ubuntu.vmdk -rawdisk \\.\PhysicalDrive1 -partitions ’5,6′” instead of the default one
problems and solutions
you need to install vbox guest additions. (6th step in the instructions)
you need to install VB extension pack and enable usb 2.0 support in the options of your instance of virtual machine (vm)
set it up in options of the vm. NOTE: you cannot use a folder that is in documents. i used c:\vbshare
to auto-mount, click on auto-mount option in settings of the shared folder and add yourself to a group vboxsf.
normal boot to ubuntu doesn’t work
when i restarted and booted into ubuntu, the windows manager didn’t start. the problem is that when you install vbox guest additions it overwrites your /etc/X11/xorg.conf file.
sudo Xorg -configure
save the old (vbox) xorg configuration just in case
sudo cp /etc/X11/xorg.conf /etc/X11/vbxorg.conf
sudo cp /root/xorg.conf.new /etc/X11/xorg.conf
restart and boot into ubuntu
so you have to switch between xorg.conf files for now. i haven’t found a fix for it yet.
UPDATE: with VirtualBox-4.0.8-71778-Win, i got an error that hd0 is full, press any key… i ignorred it and pressed any key. then gives an error that looks smtn like “error ahci-0-0 existing verr_access_denied” i had to go into vm’s settings>storage> SATA controller> check use host i/o cache. note currently i use ubuntu 11.04 with guest edition installed from apt-get
