The Settings page saved whatever was posted, and some lists offered values the panel cannot use: - Quota Debug could not be turned off: "False" is a non-empty text and counted as on. - VM Clone Name Prefix showed as a True/False list, so no prefix could be typed, and touching it set the prefix to True. - Disk SCSI Controller listed " lsilogic" with a space, never shown as chosen, and virtio-blk, which is no SCSI controller. - VM Machine Type listed x86_64, an architecture; VM CD-ROM Device listed virtio, a bus a CD-ROM cannot use. - Logs per Page and Disk Owner UID/GID are read with int(): a letter broke the logs page and VM create. A migration fixes the lists and moves a value they no longer offer to the default (the clone prefix keeps its text). A listed setting now takes one of its choices, and every number setting a whole number in its range, checked before it is saved.
