I think you are in a no win situation. Stay with 32 bit an you loose a bit of ram but go with 64 bit and really gain very little and run the problem of a full upgrade. If test system then go with 64 bit but you will not speed up anything. In fact by the time you end up, the net gain will be nill.

The base system is going to eat up a lot of ram as well the each VM overhead. Even if you move to 64 bit you still can't access all of the 4G. You might get lucky to get 2.2 left for the entire VM. Then you'd have to split that at 120% loss for each vm or more.

Post your systems specs. They may not be fully vm supported.
Thanks for that depressing news, I think this should be enough information -

The reason why I want to do this, is because I want to run Oracle linux, if the worst comes to the worst I will have to replace my Mandriva installation with Oracle Linux.

Your biggest issue is this. http://ark.intel.com/VTList.aspx Not a VT-x processor.

So, why can't you run Oracle linux with 2G?

They have I think a VM image already on their site. Download it and run it.

I had that problem with an older machine, I had to tell the kernel how much ram there was. You can use this kernel parameter.

mem=nn[KMG] [KNL,BOOT] Force usage of a specific amount of memory
Amount of memory to be used when the kernel is not able
to see the whole system memory or for test.
[X86-32] Use together with memmap= to avoid physical
address space collisions. Without memmap= PCI devices
could be placed at addresses belonging to unused RAM.
Add it to the list of kernel parameters in grub.conf or lilo.conf (depending on the bootloader you use).

I will try to download it when I have export validation

At the moment when I run Oracle Linux on my virtual machine it gets slow.
If I don't have any browsers on my machine and Oracle Linux is only in command line it is possible. However sometimes I want to check something on the internet!

Thanks after back up I will try that.

"when I run Oracle Linux on my virtual machine it gets slow." because your processor doesn't support VT-x.

That makes sense thanks. So basically my choices are :-
1) Install Oracle linux on my machine as the main operating system - not ideal but possible
2) Install it on a spare machine - which I don't have at the moment.
3) - I would guess there is no third choice.
4)Install a different linux which you can use to run Oracle - not much of an improvement over (1) nor pratically much different - need to back up my data and install it etc.

May run in dual boot. Either on hard drive or maybe even a flash or usb external drive.

Other ideas still revolve around more system or other system.

If someone made a http site like netboot.me with an oracle image you could gpxe it down. It would take a long time.

What would be the point of running Oracle linux by the way?

I should have said that. I want to for purposes of work have a test Oracle R12 system.

Mandriva is not supported - and does not install it.
