i need the function: emulate cdrom in guest, suppo
It should be like this:
-device usb-bot,id=bot0
-device scsi-{cd,hd},bus=bot0.0,drive=drive0
Libvirt has the code to generate the options for SCSI controllers, but
usb-bot only allows one disk attached to it so it's easier to make it a
element.

Could you give the detail qemu cmdline about usb-bot?

1、start vm with usb cdrom
2、 get qemu cmdline
qemu ... -blockdev
{"driver":"file","filename":"/tmp/cdrom","node-name":"libvirt-1-storage","auto-read-only":true,"discard":"unmap"}
-blockdev
{"node-name":"libv

The drive interface supports media=cdrom so that the usb cdrom
can be emulated as cdrom in qemu, but libvirt deprived the drive
interface, so media=cdrom is added to the blockdev interface to
support usb cdrom emulated as cdrom
