VirtualBox

Installation

Reference instructions can be found here:

• For VirtualBox 3.2.x:
• Add the following lines to /etc/apt/sources.list (here for Ubuntu Lucid):
deb http://download.virtualbox.org/virtualbox/debian lucid non-free
• Add the Oracle public key for apt-secure, then install

  wget -q http://download.virtualbox.org/virtualbox/debian/oracle_vbox.asc -O- | sudo apt-key add -
  sudo apt-get update
  sudo apt-get install virtualbox-3.2
  

• For VirtualBox 3.1.x:
• Add the following lines to /etc/apt/sources.list (here for Ubuntu Karmic):
deb http://download.virtualbox.org/virtualbox/debian karmic non-free
• Add the Sun public key for apt-secure, then install

  wget -q http://download.virtualbox.org/virtualbox/debian/sun_vbox.asc -O- | sudo apt-key add -
  sudo apt-get update
  sudo apt-get install virtualbox-3.1
  

The group vboxusers is created during installation.

• Users of the VirtualBox must be member of that group. New users can be added with

sudo usermod -a -G vboxusers username

• The daemon for the network interfaces will be assigned to that group.

VirtualBox requires a kernel module vboxdrv.

• The default location of the module is given by setting KDIR=[fullpath] in file /etc/default/virtualbox.
• The kernel module can be compiled with

sudo /etc/init.d/vboxdrv setup

• Enable Dynamic Kernel Module Support to deal with Kernel Upgrade

Creating a New Virtual Machine

• To boot a Virtual Machine directly from a physical disk partitions, check the page on raw disks.

Booting Existing Windows XP from Physical Partition

Here I describe my attempt at booting the existing Windows XP partition on a Dell E6500.

1st attempt

• In Windows, created a 2nd hardware profile called Virtual, copy of the original profile Profile 1
• New VirtualBox machine:
  • Base Memory 1894MB
• Using raw disk only with partition /dev/sda2 doesn't work

sudo VBoxManage internalcommands createrawvmdk -filename nxl670002-sda2.vmdk -rawdisk /dev/sda -partitions 2

This doesn't work! First Grub complained, then I tried to restore back the default WXP MBR (using either install-mbr or ms-sys but to no avail)

I created

• Virtual machine NXL670002
  • Base Memory 1894 MB
• Using raw disk with whole disk access/dev/sda

sudo VBoxManage internalcommands createrawvmdk -filename nxl670002-sda.vmdk -rawdisk /dev/sda

This works, Windows boots!

• But hangs. In Safe Mode, it hangs after loading AGPCPQ.SYS.

This post refers to problem with ACPI / APIC.

Miscellaneous work-around

• Deleted the file ...\system32\drivers\agp440.sys and agp440.sys + agppcq.sys in dllcache (check [1], post from ChaosAddict, 20100210).

→ Now windows boot until login screen, but blue screen about IRQL_GREATER_R_EQUAL

2nd attempt

• Started from base image. I compared all the drivers with a base XP + SP3 install. Disabled all additional drivers.
• Booted in safe mode... hangs... hangs and hangs again.

3rd attempt

• Started from base image again. Renamed some drivers (including agp440.sys + some others)
• Disabled VT-x, disabled PAE, disabled multi-cpu, enabled IO APIC, disabled 2D accel.
• Boot in safe mode... OK!
• Boot in normal mode... ok!
• Enabled back everything, boot in normal mode... ok!
• Installed VirtualBox Additions... ok!
• Restored all drivers, but agp440.sys... ok!
• I can even boot in native!!!

Interesting post about step-by-step configuration to run an existing Windows XP installation.

• Two posts about disabling IO APIC:[2] and [3]. But apparently this doesn't really fix anything (also the poster has a old cpu, etc).
