Greetings, I was wondering what is the proper way to configure a scsi cdrom pass-through so in when the qemu line is generated, host_Cdrom will be used instead of host_device. looking at https://gitlab.com/libvirt/libvirt/-/blob/master/src/qemu/qemu_block.c#L1090, I see that hostcdrom must be true. in order for that to be true, the following must be (see

...ote that all of the above is not "SCSI passthrough" but rather device emulation backed with a real cdrom. This is fine if you want to use the cdrom for block operations (reading) CDs. In that case qemu must use "host_cdrom" to provide functionality such as eject.
