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.

Ok, that's clear.

Thanks for your fast response !
