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 VM's console settings have no "Clear keymap" box: it wrote an empty
keymap attribute into the VM, and choosing Auto already removes the
keymap; that change is logged as "remove console keymap".
- The "Clip viewport" switch was labelled "View Clipboard".
- The full console page no longer fills the password field with "None"
for a VM without a console password.
A boot device moved up or down was rebuilt without its click handler, so
unticking it afterwards left it in the boot order that was applied; the
moved label now keeps its checkbox. An empty root password did nothing
and said nothing; it is refused with a message. Changing a NIC of a
shut-off VM gave no confirmation; it now says the device changed.
The saved console form had no initial values, so every posted field
counted as changed: saving only a password also logged the keymap and the
listen address again, each time. A listen address the form does not list
(set in the XML editor) was not a choice, so the select showed localhost
and a save moved the console there. The form now takes its initial values
from the VM, on the page and on the save, and offers the VM's own address.
The Access tab's Root Password and SSH Keys worked only on a shut-off
VM, through gstfsd on the compute. A running VM whose QEMU guest agent
is connected now gets them through the agent: guest-set-user-password
with the SHA-512 crypt hash, and guest-ssh-add-authorized-keys adding
the key to root's keys. A shut-off VM still goes through gstfsd; any
other VM is refused with "Shut the VM down, or start its QEMU guest
agent, and try again", and the buttons are disabled.
Each is one agent command with a 10 s timeout. libvirt's own calls for
them (setUserPassword, authorizedSSHKeysSet) wait for a hung agent
indefinitely, holding a worker and the VM's lock, and the domain's
agent timeout would change every other agent call of the VM too.
The agent's or libvirt's error is shown as is through error_text, so
users who do not see the hosts get no connection details, and the
attempt is logged as failed. The README names the SELinux boolean a
RHEL-family guest needs before its agent may add SSH keys.
From the Codex and agy review of the VM audit log before v3.2.0:
- Resolving an uncertain migration wrote its row without the VM's UUID,
because the migrate job writes no entries of its own; the resolution now
takes the UUID from the job's intent, so the VM's Logs tab shows it.
- A console keymap or listen address the VM could not take (no graphics
device, or a console on a socket) was logged as done although nothing
changed; it now writes no row, as an edit that changes nothing.

Operations on a VM now write their rows the way the admin audit does: one
row per operation, done or failed with a safe reason, with the user, IP and
host. Each row names the VM ("VM web-1: delete snapshot snap1") and carries
its UUID in the new Logs.instance_uuid column.
- audit_vm and failed_vm wrap audit() and failed() for a VM. A failure the
view turns into a message is caught outside the block, so its failed row
is written; busy claims, permission and quota refusals and invalid input
write nothing. No password, key or XML goes into a row.
- All VM page operations move from addlogmsg to audit_vm, and addlogmsg
goes. QoS changes and defining a VM from XML are logged now; a gstfsd
error reply (root password, SSH key) is a failed row, not a done one.
- Partial results are rows of their own: the VM delete, then each disk
delete; the disk detach, then the volume delete; the migration, then a
failed autostart restore, NVRAM removal or record on the target.
- Migration rows use the compute name as the host column, as every other
row does.
- VM job rows (create, clone, snapshots) and their resolutions carry the
VM's UUID; snapshot job intents now record it. The owner rows of the VM
page and the accounts pages, and the ownership system rows, carry it too.
- The Logs tab loads vm_logs/<pk>/ and shows the rows with the VM's UUID,
so a rename keeps the history, two VMs with one name are told apart and
a VM on two computes is one VM. It gains a Result column. Rows from
before this change have no UUID and stay on the Logs page only.
