The resize tab enabled disk growth only for a shut-off VM, although
resize_disk already grows a running domain's disk through blockResize.
The button is now enabled for running and paused VMs too. A live test
grows qcow2 and raw disks of a running and of a paused VM and checks the
size the guest sees, the volume size, the unchanged persistent definition
and the state.
The Destroy button was disabled and the confirmation page refused a
paused VM ("Instance is suspended, cannot destroy!"), while the destroy
request itself stops a paused VM like a running one. Both now offer it.
Redirects to #access (root password, SSH key) and other top-level panes
opened nothing, and some sub-tab ids did not exist. static/js/instance_tabs.js
opens the pane and the tab that holds it from the page structure, and
opens Settings on its first section, without leaving the current tab;
guest OS info is loaded whenever it is the section opened. The bottom bar linked to
host pages, which only administrators may open, and showed host names to
everyone. A stray </li> is removed; the page's inline scripts and the tab
logic are checked with Node.
Power cycle force-stopped and started a template, which power on refuses.
A non-staff owner with is_delete could delete a template that the
template rule otherwise leaves to superusers and staff owners;
get_instance(perm_type="delete") now refuses it, and the page offers
Destroy by the same rule.
The documented rule held only for snapshots: an owner with is_change could
still resize a template, set its root password and SSH keys, change its
options and console settings. get_instance(perm_type="change") now
refuses a template to owners who are not staff, which covers every change
view and the API; the per-view snapshot checks it replaces are removed,
and the page offers those controls by the same rule. Viewing, the console,
power (a no-op on a template) and cloning are unchanged.
The page showed controls the backend then refused: power to global
viewers, the console, virt-viewer and VDI controls and the root password
and SSH key forms to viewers, resize to staff, per-vCPU hotplug, video
model and guest agent to non-superusers, clone and options by the clone
permission alone, snapshots without change permission. The page now asks
the views' own rules (owner, is_change, clone and snapshot permissions,
the template rules). OS info, opened from the header, is there for every
viewer; the XML editor and tab restoring after a redirect no longer throw
when a pane is absent; Settings opens on the first section the user has.
The authorization matrix also covers a template VM, the template clone
rule and the template snapshot rule.
