danpb has mentioned that Linux gets this information from SCSI INQUIRY
response. So it's up to the USB Mass Storage Device to decide whether
or not it wants to have a removable medium.
The SCSI INQUIRY RMB (removable medium bit) tends to be set on modern
USB Mass Storage Devices. Of course they don't actually have a
removable medium.
One side-effect of setting this bit is that Windows Auto-Run will work
if RMB=0 but not work if RMB=0. Also, on RMB=1 devices only the first
partition is displayed by Windows - you can't have more than one
partition on the device.
For more information, see:
http://www.microsoft.com/whdc/connect/usb/usbfaq.mspx
So at the end of the day, it's up to QEMU whether or not to mark USB
MSDs as having removable media. Since modern devices tend to set RMB=1,
we probably should too.

"One side-effect of setting this bit is that Windows Auto-Run will work

A sampling of physical USB devices:
1. Noname 2GB USB stick: RMB=1
2. Nexus One USB storage: RMB=1
3. LaCie USB harddisk: RMB=0
I suspect there's no setting that will satisfy everyone here. It makes
sense for a USB harddisk to set RMB=0 because that allows you to put on
more than one partition under Windows.

We can make it a qdev property.

Stefan, you fixed this in QEMU 24 Jan 2011 so this bug can be marked as
Fixed Released?
SEE: http://lists.gnu.org/archive/html/qemu-devel/2011-01/msg02425.html
Append ",removable=on" to a device definition for USB Mass Storage Devices to override the removable bit (but off by default):
> qemu -usb
> -drive if=none,file=test.img,cache=none,id=disk0
> -device usb-storage,drive=disk0,removable=on
However, I cannot see a way to set "removable=on" for usb-storage
devices started via libvirt (in 12.04, with libvirt-bin
0.9.8-2ubuntu17.1 and virt-manager 0.9.1-1ubuntu5.1).
So, is a feature request required for virt-manager to expose this option
for virtual disks (default to 'on' for bus='usb') and add support to
libvirt's XML to set "removable=on" ?

Yes, I just checked libvirt.git/master and cannot see a way to set the
removable option. I'm afraid libvirt also needs changes.

Setting status to "Fix released" according to comment #5 (if there is
something left to do for libvirt, please consult their bugtracker
instead)
