Hi,Can someone tell me how QEMU implements the discard feature of the file system? Does it simply write zeros to the discarded blocks? Are there other options to transfer the discarded blocks to the hosting file system as a discard call? I am currently using qemu-kvm-0.13.0. Thanks!
Regards, Charles Chou
