Hello developers, i am trying to test trim/unmap of qemu.
My config is Gentoo x64 stable branch, kernel 3.10, libvirt 1.1.3, qemu 1.5, lvm2（non-thin） on ssd How can i check that if: 1. qemu receives trim/unmap from guest 2. qemu is punching hole/issue blkdiscards/writing zeros? Thanks in advance. ching
