- libvirt refuses to refresh a pool while a volume is cloned in it. The pool page, the volume list of the VM and create pages, upload planning and the API no longer fail on that refusal; they use the list libvirt has. - A new pool that does not start (unreachable NFS server, a device LVM cannot use) is undefined again, so the name is free for another try. - A pool reporting no size, such as an iSCSI pool without LUNs, shows its page instead of a division error. - Each clone dialog shows its own format and metadata rows, so a format is never shown without Convert ticked and silently ignored. - The new-volume size is labelled in GiB and is at least 1; an inactive pool shows no "None" volume count.
