# A Virtual Machine 1. Today, we will work in a virtual machine. 2. In this case, the virtual machine is purely software-based: the guest CPU is emulated in software and no hypervisor is involved. 3. You will need to work on ‹aisa›. Start by running: $ sh boot.sh 4. This will boot your own copy of the VM that we will be using. Your image is stored in ‹~/pb152/12› as ‹vm.img›. 5. If you want to start over, you can move ‹vm.img› out of the way, or just delete it. Next time you run ‹boot.sh›, you will get a fresh image. 6. When your machine boots, log in as ‹root›. The password is ‹bring it on›. 7. Type ‹cd 12› and ‹cat start.txt›.
