Why? One box-many instances Use less power-run cooler.
Potential Pitfalls Allocation-RAM/Harddrive/CPU
What is a Virtual Machine? A piece of software that acts as a piece of hardware.
Types of VMs Type 1. Direct Interface with hardware Examples: Xen
Type 2. Interface of hardware through software. Examples: VirtualBox, qemu, kqemu
Practical Advice: Try to create a seperate partition for your virual machines. If possible, limit your partition size to 4.5 GB- That way, you could dump a snapshot to a DVD to backup.
Guest Editions allows you to use your VM as a window in your OS.
Networking? Potentially difficult, because you create imaginary networking connection.
Sound? How is sound handled? You can either enable or disable it, at will. This allows you to lock down systems, hard core style.
Images? How do you find them and use them? As long as you have an iso image, you can use it, but you can use your drive, as well.
Printing? How do you do it? Potentially difficult, depending on your original OS
Can you mess around with GRUB and LILO virtually? Hell yes!
You can run SAMBA to network with your virtual machines on your own box. Map the network drive and reconnect at login, and you should be pretty much ready to go.
