Hi,
I have a question about commit
http://git.qemu.org/?p=qemu.git;a=commit;h=5500316ded9db5b10072334cde1e27fb37682240
"block: implement is_allocated for raw"
Does it works with virtio-blk ? Or does it discard support ?
Regards,
Alexandre Derumier

It is unrelated to virtio-blk. is_allocated is only used internally
(qemu-img convert and online streaming). In the future it may be
accessible to SCSI devices via the GET LBA STATUS command.
It is part of improving support. I hope to get that in 1.2, but
honestly it's not too likely.
