I may have already asked this a while ago... would it be possible for dos (free or ms) to run under xen, or does it have to be ''protected'' mode operating system? And if dos worked, what are the chances of getting some of the 386 extender (dos4gw if I remember correctly) style games working? Or is that precisely the thing that would need to be recompiled to work under xen? If only real mode dos could work, how easy would it be to modify the xen scheduler to simulate a much slower machine?

Doing it using a CPU emulator would be a gross waste of CPU cycles imho. One of the reasons for wanting a DOS domain (no need for artificial slowness here) is for keeping a few legacy applications going without having to keep them on their aging hardware, or wasting new hardware on them. All things considered, dosemu might be a better option. thanks James ------------------------------------------------------- SF email is sponsored by - The IT Product Guide Read honest & candid reviews on hundreds of IT Products from real users.

Just use dosbox. Very capable. I played Quake under it just to test it out (spent most of my time there playing Crystal Caves) or if you''re looking for more than games, dosemu.

You''d have to think through what to do about IO, though. Possibly hook into the emulation stuff that''s used for VMX guests. Feel free :-) Cheers, Ian ------------------------------------------------------- SF email is sponsored by - The IT Product Guide Read honest & candid reviews on hundreds of IT Products from real users.

You may wish to start with dosbox under linux in dom0, this ought to work. And it doesn''t eat up cpu cycles like candy :)If you want to run a single DOS on Xen, you will definitely have to introduce some "abstraction" layer, similar to the one dosbox provides. dos4gw is an interesting beast, it tries different interfaces to switch itself into protected mode (DPMI is the one i recall). That might result in some neat lowlevel hacking ;) Again, dosbox is said to support dos4gw games to some extent, so have a look there!

Hi there! I seem to have this problem of all the output (both stdout and stderr) of C part of xend (libxc) does not appear in the xend log (or on the console). Do you know what is the reason and how to change it?

ok - it seems to be in the debug log. Ignore the previous email.
