Regarding new USB widget:
User experience when USB CD drive is presented to user is wider than just
plug/unplug the USB device.
The CD may include several units, each of them can be managed separately.
If more than one unit supported on CD, single CD with number of units
requires
just one redirection channel. [At the moment due to time restrictions, we
define
CD as single unit, but I think in the future we will want to enable
multiple units on CD]
So in common case the GUI for CD drives tends to be something like tree
view.
This easily serves also local USB devices as in GTK tree view == list view.
Initially the widget was developed with single list containing all the
devices
when shared CD devices have leaves and local USB devices do not.
IMHO, this kind of presentation is better than current one which presents
local devices
and CD devices separately.
When CD drive is presented to the user on guest machine, it can be ejected
by
user action (from Gnome or Explorer). When the media is ejected, it can be
changed
on client side. So the status (ejected/loaded) should be visible and the
user should be
able to control this also on client side exactly as you can open/close the
drive door manually.
Drive lock. When CD is reqired for SW operation, the SW often locks
the drive preventing user-initiated eject. In such case, if needed, the CD
still can be
manually ejected using clip. Another option related to 'lock' is that user
may want
to prevent removal of CD by guest software and lock it on client side.
The user shall select the properties for logical CD unit and it is good to
show them
in the GUI. They include (at least):
* file name (or device name) used as media
* device attributes (vendor/product) which are used to report properties of
SCSI device
(these properties are visible to user in seabios boot screen, so in case of
2 CDs the user
can recognize the needed one). Note that 2 CDs is typical case for Windows
installation
on VM with virtio.
* Whether the CD media is currently loaded
Visible status of the device is (IMHO) good for self support. When
something does not
work as expected and you can't see anything in the GUI that can explain
this, the next step
is opening issues, sending logs etc., i.e. spend own time and time of other
people.
I disagree with the statement 'less GUI is better'. Definitely, less GUI is
simpler,
but this simplicity often increases cost of ownership.
Our solid opinion is that even current CD additions are too heavy for
existing widget.
