Ticket #18420, comment 1

-              initial
+              v1
 Wait... the guest *does* know the disk is solid state (/sys/block/sda/queue/rotational is "0"), BUT the device does not support "trim".
+{{{
 sudo fstrim /
 fstrim: /: the discard operation is not supported
+}}}
 So the problem is not with detecting ssd-ness but that the emulated disk doesn't let the guest make use of that fact to remove deallocated blocks from the vdi.
