Settings > Console was one horizontal form, and on a running VM its
Update button was disabled. The owner chose this layout from three
rendered options: the console type on top, then a "VNC connection" card
(listen address, keymap) and a "VNC password" card.
- The password is changed by an action: keep it, generate a new one,
set a new one or remove it. This replaces the Generate and Clear
boxes and their precedence, and an emptied field no longer removes
the password silently. The pane says whether a password is set; the
form no longer carries the password itself.
- A VNC password takes at most 8 bytes: libvirt refuses a longer one
("VNC password is 9 characters long, only 8 permitted"). Generate and
a new VM's random password now make 8 characters; they made 12, which
libvirt 11 refuses. A set password keeps its spaces.
- Every check is in the form, so a refused save changes nothing; before,
a refused password removal still saved the other settings.
- The settings can be saved while the VM runs: they are in the
persistent definition. A line says the running console keeps its
settings until the VM is shut down and started.
- The console type shown and compared is the persistent one; it was the
running VM's, so a pending switch to Serial showed VNC and a later
save could switch again.
- While the saved type is Serial, the VNC settings are not shown or
taken; choosing Serial ignores the posted VNC settings.

The console settings form is rendered only for users who may change console
|
|
settings, which is the rule update_console enforces: a superuser, or an owner
|
|
with both is_change and is_vnc; not for is_staff or the global view_instances
|
|
permission. The form never carries the VNC password: it says whether one is
|
|
set.
