Virtual Machine Questions

[Bill Stanley]

I have run VM's on another platform (VirtualBox onOpen Suse) but I 
wasn't very successful and I am not very experienced with them.

1.  I see VirtualBox OSE in sthe Ubuntu software repository.  Is that 
all I need to run a VM?

2.  My processor is an i7-860 with 8 Gb of RAM and has harware support 
for VMs.  I know VirtualBox can use the hardware support.  Do I have to 
install anything else (in the kernel) to enable hardware support. I am 
using Ubuntu 10.10 - 64 bit.

3.  There are a lot of OSes supported by Virtual Box but all of them 
need OS installation disks.  I do have a Win-7 install disk but the 
installation of that VM was buggy and had network problems.  I would 
like to try Win XP but do not have an install disk for that.  I have a 
Dell machine but Dell gave me no install disks with that computer.  Even 
if I had a disk it would not install on anything other than a Dell 
machine.  I guess this question is... How can I install various OSes?
