Re: [Qemu-devel] Can I mount encrypt qcow2?

[陳培泓]

It works after I replace the /usr/bin/qemu-nbd with binary I built.

My cmd is :

> qemu-nbd --object secret,id=sec0,file=passwd.txt,format=raw \
>              --image-opts driver=qcow2,file.filename=
> demo.qcow2,encrypt.format=luks,encrypt.key-secret=sec0


But I got other message:

> Block format 'qcow2' does not support the option 'encrypt.format'


Maybe it doen't support yet?
