I don't use it any more, I only needed it for a couple of days as it happens.

You see, I started from the view that Qemu is a PC simulator. So it must simulate a hard disk, a CD ROM, a network card, etc. Everything just like a real PC, but in a window. So the process of installing an OS on it is exactly the same as installing an OS on an ordinary PC. Which is usually from CD these days, but you can use a floppy too. The only difference really is everything is simulated, so you use a file containing a CD image instead of a real CD, a file containing a hard disk image instead of a real hard disk, some options to simulate a network card instead of a real one, etc., some options to simulate a mouse and video card, etc. The actual procedure for installing Windows or whatever is pretty much identical to doing it on a real PC. That doesn't mean it's easy, but the hard (or tedious) part is generally not with using Qemu, but with using a PC to install Windows or whatever. That can be quite difficult sometimes, but those wouldn't really be Qemu questions as long as it's simulating a PC ok - they'd be OS installation questions for any kind of PC. > To make this complete, all I need now is a command to tell me how > to actually boot qemu and point it to both the CD DROM (e.g. the > Ubuntu install CD, or the Windows install CD) an my newly-created > blank disk image. I think Nathaniel just posted a list of command line options. Though, "qemu --help" and "man qemu" seem to list them too. > I should note another thing: Because the problem > I'm pointing to is so fundamental, you're much less likely to hear > about it.

I notice in your > question that you assumed that I knew how to install at least one OS > with qemu; I don't. Actually I didn't assume that. I assumed you knew how to install at least one OS on an ordinary PC. Installing it in Qemu is pretty much the same, other than using simulated devices instead of real ones. And the simulated devices are really easy to specify. There's a command line option to say that a .iso file contains a simulated CD-ROM image (the same .iso file you'd use for writing a CD-ROM), another option to say what file contains the simulated hard disk, another option to say that you want to boot from CD-ROM (simulated) instead of simulated floppy. I don't have Qemu installed right now to say what those options are exactly, but I remember that's not much more than those, if anything, and then you get a window which looks just like a PC booting off CD-ROM... and you do the same as you would with a real one from then on. -- Jamie _______________________________________________ Qemu-devel mailing list Qemu-devel@nongnu.org http://lists.nongnu.org/mailman/listinfo/qemu-devel
