Re: [Qemu-discuss] manipulating raw disk image as non-root user

[Kris]

I have a solution, but it seems a little complex: you can run a program (service A), and it provide some restful API. Then when Jenkins call your script, and your script call service API. Last, service A do what you want as root user.

Since you can run Qemu as a non-root user, and you can present an
arbitrary file to it as a disk, it seems that you should be able to
use the standard disk tools within a Qemu guest to do what you want.

Thanks Dale.  I was hoping I could do something like this.  I'll explore that further.

Tony, I am wanting to run as non-root because it is my Jenkins build-server that will be doing all of this which needs to run as non-root for security sake.  I want the last stage of my build to produce a uSD card image.

Can't do that unfortunately.  It's still elevated privileges.  Jenkins won't allow it.
