Subject: [Qemu-devel] [PATCH v2 0/3] usb-msd: Add usb-storage, removable=on|off property
Date: Tue, 18 Jan 2011 10:10:39 +0000	[thread overview]
Message-ID: <1295345442-16218-1-git-send-email-stefanha@linux.vnet.ibm.com> (raw)

Allow overriding the SCSI INQUIRY removable (RMB) bit for scsi-disk and usb-msd
devices.  In particular this addresses the problem that some usb-msd devices
have the bit set while other do not have it set.  Now the user can choose and
get desired guest behavior.

qemu -usb
     -drive if=none,file=test.img,cache=none,id=disk0
     -device usb-storage,drive=disk0,removable=on

The default is off.

v2:
 * Rewritten to override the bit at the scsi-disk level
