[Qemu-devel] resizing qcow2 images?

[Tomasz Chmielewski]

Is it somehow possible to resize qcow2 images?

The only "method" I know is to convert an existing image into a 
different format, resizing it, then converting it back to qcow2.

Which is quite lengthy and means plenty of IO. Moreover, it gets even 
more tricky if the image is already more than 50% of your storage space 
and you still want to increase its size.

Are there any better solutions for qcow2 resizing?
