Re: Best virtualization: Ubuntu within Windows or Windows within Ubuntu?
For situation 1) Security won't be as good as natively running Ubuntu (though to be fair it all boils down to the user). But it's easier to break into a Windows machine since it has a bigger market share. Ports would be controlled by the Windows firewall (or whatever firewall you choose to install which would usually deactive the windows one). Permissions, what do you mean? In Vista they're controlled by the UAC and in Ubuntu..well if it was running virtualized Ubuntu would apply its permissions to its own file system.
And with 1 GB? I doubt it. Perhaps if you weren't running any memory hogging programs (e.g. Firefox, Open Office, Thunderbird). But my 1 GB desktop with its current load of screenlets, firefox, thunderbird, pidgin, and Open Office running is around 800 MBs of usage). Virtualization requires a nice bit of RAM, then the RAM used by the virtualized OS itself.
My laptop has Ubuntu with a virtualized XP. It uses about 1.5 GBs of RAM (with the programs running in Ubuntu) + 512 MBs of RAM for the stripped down XP I run. Vista requires alot more I think judging by its normal use on my laptop.
