This commit contains modified files related to CD sharing feature.
The feature adds ability to share one or more CD images
(or local CD-DVD devices) with the guest by emulating
USB CD devices connected to guest system.
Prerequisites:
Guest system shall have USB2 or USB3 controller and one or more
USB redirection channels. Each emulated CD device currently
uses one USB redirection channel.
Usage from GUI:
New USB device redirection widget includes 'Add CD' button that
allows selection of ISO file which will be used for emulation
of USB CD drive.
Usage from command line:
Added command line option '--spice-share-cd=filename' which
allows to create one or more emulated CD drives.
Sharing local CD drive:
For sharing local CD drive use file name of respective device,
it depends on the operating system of client machine.
Example for Windows clients - d:
Example for Linux clients - /dev/cdrom
Build backward compatibility:
The feature can be disabled by build configuration:
--enable-cdsharing=no disables CD sharing (USB redirection
GUI uses new USB redirection widget)
--enable-newusbwidget=no also disables CD sharing (USB
redirection GUI uses old USB widget)
Notes for Windows build of 'VirtViewer':
In order to show proper icons in new USB redirection widget
the installation package of VirtViewer shall include
following icons:
"media-optical", "network-transmit-receive", "network-offline",
"dialog-warning", "dialog-information",
"preferences-system","system-lock-screen","media-eject",
"edit-delete", "list-add"
Automatic redirection of emulated CD devices:
Same as one for local USB drives:
- shared CD devices created by command line redirected
according to 'redirect-on-connect' filter
- shared CD devices created during session redirected
according to 'auto-redirect' filter
Disable redirection of emulated CD devices on server side:
Same as for redirection of local USB drives:
-device usb-redir,filter=<filter> option of qemu
