Hi, I've changed the "default" storage-pool from "directory-based" to a "pre-formatted block-device" since my /var/lib/libvirt/images is on a partition of its own. I would like to use the "discard" option as well as other (noatime etc) on this filesystem. Is there a way to specify mount options in the storage-pool XML definition? Thanks, Jorge p.d. the reason for the change is that I don't want the partition to be mounted all the time (just when I start libvirtd).
