How does stuffing all virtual machine parts into one file help you to load a virtual machine entirely into RAM? Surely, one could manage to load multiple files into RAM. Additionally, I don't see how it helps security if you move the hard disk for the virtual machine into RAM. It should be fully sufficient to let the inital hard disk sitting in the file system and to record changes to the virtual hard disk, only. qemu supports such recordings (shadowed file systems) already and if it makes you happy, it shouldn't be too hard to keep the record of changes in RAM. This saves you a lot of startup time as well als hundreds of megabytes of RAM. For an approach without any changes to qemu, you could have a look into how (Linux) Live CDs work. Most of them work without a writeable hard disk, managing all the RAM-disk stuff themselves. Markus - - - - - - - - - - - - - - - - - - - Dipl. Ing. Markus Hitter http://www.jump-ing.de/
[Qemu-devel] Emulation: Building solid files
Hi beastcoders, My question is if you are thinking in improve Qemu to add singular characteristics whose aren't implemented in any VM sofware: I.E.: Building virtual machines taking only one big binary file (merging Qemu engine and HD image file). It could be good for future portable aplications. I thought this because I'm triying to do the simplest-ultra-secure Internet navigatior. The idea is to generate a VM (with the lightest/functional O.S. posibility and increase speed at top) to content a Firefox installation (with the most used complements into it). The main is to load all this VM into the RAM and when it will turn off, it never has to save the session changes, it allways must start at the beginning point. Sorry, allways not. Sessions only will be modified in security-updates and/or Firefox-complements. Troyans, virus, spyware... will be better managed by people who hasn't any idea in computers, because I wan't to transmit the simplest concept: If you want to use the Internet to do critical operations and you are very scared by hackers, virus... because you hasn't any idea of manage security in computers, you only have to run another VM-Firefox to enter in I.E: bank sites and don't worry because you are keeped by the security of a castle I only want if you will implement that kind of emulation.

Re: [Qemu-devel] Emulation: Building solid files
you could pack the binaries and the image into a 7-zip sfx (but that is for windows hosts only). just google for it and you'll get the procedure. I've done it a few times already. what is your host ? linux or windows ?

Re: [Qemu-devel] Emulation: Building solid files
You could do that with a shar. That's sick and wrong, but cool. Problem I have with anything else is that in Solaris 10, you can't statically link anything any more so it would have to unarchive itself to a separate location and run.
