In order to show you the VirtualBox potential, and make easy the migration to Ubuntu for the users of XP, who want to use it from Ubuntu. We are going to see how you can virtualize an made XP partition from Ubuntu 8.04 suing VirtualBox.
We can find the same solution with VMware Workstation at Kriptópolis (Spanish), but this product can be used 30 days. I probed with the free VMware Server product, but it do not provide the partition virtualizing property.
Then with no doubt we can say that VirtualBox is the most durable solution, although Open Source.
Ensure the correct VirtualBox Edition
Take care at first on the installed VirtualBox version, it must be the commercial one (not the OSE one). The other has not the possibility to visualize physical partitions, from a Virtual Machine. We take the explanation of this at this link.
Copy a Hardware Profile in our Windows XP System
The next caution is to create a sencond “Hardware Profile” at our XP System, because when we boot our Virtual Machine the hardware is the standard provided by VirtualBox, and XP will start to detect and install, and remove the old drivers.
On this way we could boot our XP partition from GRUB choosing a “Hardware Profile” not modified. We can create this profile at: Right mouse button over My PC > Properties > Hardware > Hardware Profiles > Copy; and create the second Profile “Profile 2″ which will be the modificated on the first boot from VirtualBox:
Create a Virtual Machine
First we have to create the Virtual Machine with the usual steps.
Create anew machine:
Selectin Windows XP as guest System. In the next screen we have to asign the RAM memory:
We do not assign any Virtual Hard Disc, we will do it through the terminal in the following point.
Linking the VM to the partition
At the poit 9.9 in the VirtualBox Users Manual we have the way to procceed to create a Virtual Hard Disk, from a physical partition. Execute the following command:
VBoxManage internalcommands createrawvmdk -filename /path/to/file.vmdk -rawdisk /dev/sda -register
Then we will create the Hard Disk file.vdk referenced to the /dev/sda device.
To use this disk you must to add your user to the disk system group (to manage dthe sda device)P:
sudo usermod -a -G disk
Open the file /etc/group and modify your user in a line like this (to manage the applicatiion):
Reboot the system to make theese changes. And bind the HD file to the Virtual Machine with the following command:
VBoxManage modifyvm XP_ant -hda /path/to/file.vmdk
We must not have any problem booting the VM, in the following image you can see my XP Desktop from Ubuntu:
