The Migrate tab offered every other host alike, and its plan showed neither a file of the same name in a destination pool nor the disks of the VM's next start, which the job then refused. Now: - When the tab opens, the hosts are checked first: one that cannot be reached, or the VM's own host under another record (the same libvirt host UUID), is shown with why and cannot be chosen, and the disks of the first one left are checked. The job refuses the VM's own host under another name too. - A pool of the destination that has a file of a disk's name is shown but cannot be chosen for it; a disk no pool can take refuses the form. - The next start's file disks the migration does not carry are listed; one not on storage both hosts share refuses the form, as the job does.
