I want to have send/receive also and I use QCOW2 on top of ZFS to have
"switch-to-that-snapshot" capability, what ZFS not supports.

I don't want to use another FS over ZFS which I need to use when using LXC
(in addition to KVM). Then I need to trim it manually to get back free
space in ZFS. I have this at the moment and I do not like it.
