Imagine you want your physical computer to run as a virtual machine, maybe because you want to try some dangerous changes, maybe because you want to sell one of your two laptops. That's what this article is about. Your computer can be on Windows or Linux, no matter.
How to
Let's call the computer you want to virtualize moon and the computer you want to use as a host for the virtual machine earth.
-
Get an image of moon's harddisk. Do one of the following:
- /> Use a USB disk to store an image of the hard disk: dd if=/dev/sda of=/hdimage.img This can be used if your harddisk is /dev/sda and you want your image file at /hdimage.img. Transfer moon's image over the network: dd if=/dev/sda | ssh root@earth "cat > hdimage.img"
