Qemu can't do that yet (it shares hardware via the help of the host OS, of course, but not direct access). If you had qemu running multiple OSes, and all of them could access the same hardware "virtually directly", that would be simply amazing.

Anyway that's good to know. Thanks! No, it currently only works with PCI. ISA, AGP, USB, and traditional hardware can't be accessed directly yet (tho it is theoreticly possible). > > Best regards > > Peter K > > -- > We Can Put an End to Word Attachments: > http://www.fsf.org/philosophy/no-word-attachments.html > > > _______________________________________________ > Qemu-devel mailing list > Qemu-devel@nongnu.org > http://lists.nongnu.org/mailman/listinfo/qemu-devel > -- Infinite complexity begets infinite beauty.
