- The host graphs and the machine/bus lists connect inside their libvirt
error handling, so a down host gives empty answers instead of a 500 page
the polling script drops.
- The Secrets page lists vTPM secrets instead of failing on them, and a
secret without usage data shows an empty cell instead of "None".
- A TCP/TLS host takes a SASL password longer than 14 characters and a
login up to the Linux limit of 32.
- The compute edit page says "Edit Compute"; a host without VMs no longer
closes an extra page element; the memory graph is labelled MiB.
The edit dialog of a secret was filled with its current value, so every
readable secret's value was in the secrets page's HTML. A private
secret, or one with no value yet, cannot be read: its field held the
text "None", which is valid base64, and saving the dialog unchanged set
the secret to the three bytes it decodes to. The dialog now only writes
a new value: the field starts empty, is a password field and is
required. The page no longer reads secret values, and get_secret_value,
used only for that, is gone.
