Re: [Qemu-discuss] qemu-nbd: knowing which nbd device number to connect

[Raphael Bauduin]

Hi,

thanks for your answer.

But this lists all nbd devices, even those not connected, so it doesn't do what I need.

This may be all you need:

 ls /dev/nbd*

Unless the nbd model supports disconnection and reuse
of an existing device. Sorry, again I'm just guessing.

Please tell me if I'm being a nuisance.
