hai frds,
(1) i am intrested to test other types of Linux But now im using Debian and 512 MB swap space Can i use the same swap space for other Linuxes or i want to partiton my hard disk for another Linux swap
(2) How much swap space should i allocate for the my computer with 256Mb RAM
urs friendly, K.Ponniah

You can use the same swap space, though not at the same time.
The swap partition is a special partition type that the kernel uses as a scratchpad area.
(2) How much swap space should i allocate for the my computer with 256Mb RAM
Your 512MB is fine.

At the same time??
if you run two distros on a dual cpu machine at the same time (one distro per cpu), you will need two separate swap partitions

How will you do this? I've never heard of this thing. Logically thinking, at one time you will run one distro which will take command of both the CPU's (if its an SMP).
Even if you manage to run two distros at the same time by using VMWare or tool alike, still you will find that the underlying OS for the processors still remains one.
Can you point me to some resources where this is explained in detail?

The point of two processors is that you can run two processes simultaneously, at exactly the same time. It has nothing to do with whether you have 1, 2 or 3 distros running simultaneously (time shared).
In fact, the more I think about this, the more I'm convinced that it's even possible to run multiple distros simultaneously on a single processor machine. All you need to do is segregate memory and swap correctly. I think IBM does this on their big machines.

Can someone explain to me why anyone would want to run 2 distros simultaneously ?

I believe that's the question that's stopped everyone from trying :P
OTOH, invention does not only come from necessity, it also comes from someone asking "why can't we do this?" without caring about the practical necessity. That's what separates the geeks from those that follow the crowd.

Look at me. I'm so intelligent and I use smart words to shout it out.

Sometimes there is a need of testing several bits of software on different platforms. Instead of investing money in different sets of hardware and software for each distros/platforms, we can use tools like VMWare which allow us to run several distros on the same machine cutting all the hardware and software costs.
This is the primary reason why people wud want to run different distros simultaneously.

Multiple distros simultaneously On single machine ??
I have pentium-II 400MHZ. with SuSe 9.1 and Red Hat 9.0
I can Run SuSe's X desktop On tty7 and Red Hat's X desktop on tty2 simultaneously with single swap partition and 192(64+128) MB RAM
Is it same what u r saying Multiple distros simultaneously On single processor machine ??

I presume running multiple distros concurrently does not imply running X from different partitions. It would be running a complete virtual machine startting from the kernel booting and loading init and so on. Something like Vmware. A complete OS and not just the UI component.

I currently have Fedora and Knoppix installed on the same hard disk. I don't run them simultaneously, but then that's because I have no use for that. Yes, they do share swap space.

I was talking about having them running complete instances of the machine simultaneously. Both would have tty1-7 (or more), both would have their own keyboard and display (shared through some mechanism), and their own memory space (completely separate). Both would share the network, very likely having two different IP addresses (possible on a single network card), and you'd be able to ssh in to either at the same time, and even from one to the other.
Also note that I haven't figured out how to do it yet, but unlike many, I don't say it's impossible... I'm pretty sure that it can be done.

I think All these things are possible using VMWare.
Thanks for explanation.

VMWare runs on top of another operating system. I'm talking about running directly off the hardware.

Thats the GSX Server. The ESX server runs directly on IA-32 / 64 hardware and supports RH/Suse/Win as guest OSes.

I believe, some of those things are possible with the Hurd. One can use two independent kernels at the same time.

They'd run as services within the HURD microkernel. Almost, but not the same thing. There's a very tiny difference in that, with the hurd, you get a scheduler. With two kernels running on their own, how do you handle that?

Yeah., you can run the Hurd on Hurd., something like a sub-hurd. But I'm not sure whether all the features mentioned by the OP would be available.

Yup. Correct. That's the philosophy behind multiprocessing.

All I wanted to ask was that I havent heard of any solutions till now which do this. The ones which were in place are on Mainframes which you mentioned as big machines. On server grade computing these are still unheard of. Probably that's what Kenneth Gonzalez is working on.Seems like the poor guy is in stealth mode.
