Hi,

It is a git clone obtained on November 2 by
git clone git://git.qemu.org/qemu.git
I see a file VERSION with date Nov 2 13:41 (+0100)
$ cat VERSION
0.15.90
$ git describe
fatal: No annotated tags can describe
'e072ea2fd8fdceef64159b9596d3c15ce01bea91'.
However, there were unannotated tags: try --tags.
$ git describe --tags
v1.0-rc0
Should i run
git pull git://git.qemu.org/qemu.git
? (My clone is still slightly altered. Will this be a problem ?)

Is this realistic enough for passthrough ?
Shouldn't qemu forward all SCSI commands to the host operating system
in this case ?

Up to now it appeared better to use the explicitely prescribed
method with REQUEST SENSE.
It is not a showstopper anyway. Just a little beauty flaw.
There are also some drives which do not report proper progress.
I have this topic on my todo list, together with a more graceful
handling if SET STREAMING fails.
Currently i am at the item
- Test all libburn write models of CD, DVD, and BD.
Write a summary of all results.
I plan to check DVD+R tonight. BD-R and BD-RE tomorrow.
Have a nice day :)
