[Qemu-devel] [PATCH] SCSI allow removable SBC disks

[Ronnie Sahlberg]

List, Paolo

Please find a small patch that adds a new "drive" keyword "removable".
When used together with SCSI DISK devices, this makes the emulation
support removable scsi disk.

Example: -drive file=./scsi-disk.img,if=scsi,removable

Emulation of SCSI DISK with removable media currently pass all my tests for
SCSI removable media and behaviour of STARTSTOPUNIT/ALLOWPREVENTMEDIUMREMOVAL
