Since the image is on a logical volume, it may not have been cleared prior to use by the guest; or the guest is busy enough that it has overwritten all the blocks in the image. You can try a manual trim by creating a large file in the guest consisting of all zeros, then deleting it: dd < /dev/zero < /zeroes rm zeroes Afterwards you'll get a much smaller qcow image. Of course this requires working within the guest, and there is the risk of disrupting the guest by reaching the ENOSPC condition. -- error compiling committee.c: too many arguments to function -- To unsubscribe from this list: send the line "unsubscribe kvm" in the body of a message to majordomo@xxxxxxxxxxxxxxx More majordomo info at http://vger.kernel.org/majordomo-info.html
