upcoming libnfs versions will support logging debug messages. Add
support for it in qemu through a per-drive option.

Examples:
   qemu -drive if=virtio,file=nfs://...,file.debug=2
   qemu-img create -o debug=2 nfs://... 10G

Thanks for pulling this.

Question: Is it possible to insert a CDROM other than with the 'change'
command?
The change command obviously does not support file.debug parameters...

Not that I'm aware of.

You may be able to hotplug SCSI CD-ROM drives, but that's not the same
as ejecting/inserting CD-ROM media.

Sounds like an item for the block layer todo list:

I think Max' media handling series might implement this or at least go a
step in that direction. CCing Max.

Since with that series, you can insert any BDS as a medium, yes, it naturally does.

But for now, wouldn't JSON file names work?
