[Qemu-devel] [PATCH 0/4:] misc scsi disk/cdrom fixes/improvements

[Juergen Lock]

While attempting to fix physical cdrom support on FreeBSD hosts (patches
for that shortly) I came across a few deficiencies of the scsi disk/cdrom
emulation which I patched as follows:

1. Use correct sector size for cdrom Read TOC command
2. Implement cdrom load/eject functionality (Start Stop Unit command)
3. Add asc 0x3a, ascq 0: Medium not present to NOT READY sense
   (needed to keep some guests from retrying causing long sleeps in the
   kernel)
4. Implement Test Unit Ready command (return NOT READY as above
   if !bdrv_is_inserted(...))
