Hi, Thanks to malc, I started working on this again. It should now work reliably in read-only mode. The read/write support is somewhat beta. That is, it works for my setup, but it might well break under obscure conditions.
What has changed? A lot. For example, it is now possible to emulate a
floppy:
-fda fat:floppy:my_directory/
Note that while a floppy is eject'able, the maximum size the guest OSes
accepted in my tests was 2.88MB. Not very much.
To add write/support, do
-fda fat:floppy:rw:my_directory/
To have a sane write support, I had to include the bdrv_make_empty() patch
I sent to the list a few weeks ago, since it was not applied...
What you *never* should do:
- use non-ASCII filenames.
- use "-snapshot" together with ":rw:".
- expect it to work when loadvm'ing.
What's next?
- add bootsector support
- fix bugs which were sent to me by helpful people
- add a timeout so that a commit is only tried after some time
has passed since the last sector was written
- maybe support FAT32 (I am not yet convinced that this is needed)
- maybe create block-visofs, so that huge files can be mapped into
the guest system, and be updated via "eject" in the monitor
- world domination!
Ciao,
Dscho
