Re: [Qemu-devel] Help: Convert HDD to QCOW2 img

[Halsey]

Hi Stefan, 

Thanks for so much info you provided. 

Okay, I would keep qemu-devel mailing list in the loop, no problem.

Currently, I have finished the coding of the wrapper, now testing the 
bdrv_read/write qcow2 img. I would look into these libraries and incorporate 
them based on the concept of interface design.

Thanks.

Halsey
