I have old PIV 1.8ghz, 512MB memory, 40GB HDD, computer with Debian squeeze on it. I currently work on it by connecting to it over SSH. I'm interested in testing/learning/trying out/playing with some things on Linux so I would like to set up a virtual machine on this box for this purpose so in case I mess up something pretty bad I won't need to reinstall whole OS ( PC currently doesn't have any monitor either).
Since PC is 32 bit I'm not able to use KVM to which I'm used to. Can I get some recommendation for a technology that would suit my purpose?
P.S. I know that memory is somewhat low, but I intend to use only 1 VM so I hope it will be enough.
