Thanks Micheal, I did a fair bit of testing this morning trying your
Quick clarifications - by:the following:
*Have you tried using scsi for controller and virtio-scsi for*
Did you mean setting "SCSI Controller type" in "Options to VIRTIO and the
"Bus Type" for the disk to "SCSI"?
Re the results - it made no difference for me, still fat populated.(using a
test empty disk).
However - did you try this with compression set to "off"? because to me
from your results it looks like what your seeing is the effects of disk
compression, not thin provisioning.
