Hi. I have one guest that I created with virt-install comand option 'sparse=true'. As i want to use now this guest for I/O tasks (DDBB) and i want to improve performance, I want to convert the disk.img from sparse to no sparse (obviusly without format it). How can I do this task without loosinf the disk image data?. Thank you.
