RE: [Qemu-devel] Patch: virtual vfat support

[Andreas Bollhalder]

Hello

I tested the QEMU.EXE from FreeOSZoo with your patch on WinXP.
Starting QEMU.EXE like the following:

D:\TEST\QEMU\qemu.exe -L . -localtime -m 32 -isa -cirrusvga -user-net
-enable-audio -boot c -fda bbe-fd.img -hda bbe-hd.dsk -hdb
vvfat:/TEMP/2

The directory "/TEMP/2" is in the D: drive. It works fine with FreeDOS
Beta9. Unfortunatly, I can't change the path to another drive
(partition).

I tried

/D/TEST/2
D:\TEST\2
/D:/TEST/2

The one introduced is the only one working.

Nice, sorry about my lot wishes, usage of UNC path's...

Great work, really!!

Andreas

Of course this doesn't work. As D:\ is already the host directory /TEMP/2,
you would try to change to /TEMP/2/TEMP/2 with this command.

BTW, what exactly do you mean by "another drive" and "partition"? The
VVFAT driver transparently builds a hard disk image for your host
directory, which behaves like a drive inside QEmu, having exactly one
partition with a VFAT file system.

BTW(2), if anybody has suggestions for a better name, please tell so.

Hth,

You misunderstood what he meant. On his *host* system, the D drive
holds the temp\2 directory, as in d:\temp\2. QEMU is also installed in
the D drive/partition, so specifying /TEMP/2 goes to the root of the
filesystem in this partition. He couldn't figure out a way to change
to another path in another partition/drive, say, e:\temp\qemu , or
even a CD drive letter: having a virtual VFAT partition built on top
of a CD directory structure would work around having to make a ISO
image of the disk in a considerable number of situations.

I haven't tested your patch yet, so I can't say I figured how to
change drives myself. Maybe \\.\e\temp\qemu as in my example above?
I've seen such UNC convention work in QEMU before (more specifically
the discussions on Japanese Knoppix and QEMU).

To export a directory on another drive just put two backslaches instead of
only one like this vvfat:d:\\temp, I have not tried with cdrom drives,
just hard drives

That's right, but I know now why, it's because the directories on
other host drives have been holding more data the vvfat drive could
represent and QEmu quits without a message. Now I know that, I can use
other host drives too.

This would be the nice way. Or maybe one likes more an URL like
"sftp://myhost.mydomain/mydir/myimage" ?
