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=EF=BC=88non-thin=EF=BC=89 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
