qemu 0.10.0 - cd/dvd drive access problems

[Doug Barton]

One of my main reasons for wanting to install qemu was to be able to
use Windows tools for things like archiving DVDs. Now that I have qemu
working pretty well for most things, I tried to start using it for
DVD/CD access and it's not working well at all. I installed XP via a
typical installation CD, so I thought I had it made in this area. :(

I'm using '-cdrom /dev/acd0' the same way I did for the install. If
there is a disc in the drive when I start qemu I can "see" the disc,
and copy some small files from it. However trying to copy/read large
files (say, 1G) doesn't work at all. I get an error saying that sector
of the disc cannot be read (this is with known-good discs). I tried
with and without the cd-rom DMA compile-time OPTION, no luck. If I
remove the disc from the drive, or if there is no disc in the drive
when I start qemu, inserting one after it starts produces no results.
Every time I try to access the drive I get the "Please insert a disc
into drive D:" error message.

I'm using a fairly up to date 8-current as the host, btw.


Any suggestions?

Doug
