A quota refusal put the English name of the quota (cpu, memory, disk,
instance) into a translated sentence, so a Turkish page read "memory
kotası doldu". check_user_quota now returns which quota and its numbers
(QuotaExceeded), each quota has a whole sentence, and the refusals put
that sentence before what is refused; QUOTA_DEBUG adds the numbers as
before. The clone job stores the refusal as a message, so the Jobs page
shows it in its reader's language.
The connection errors of vrtManager (did not answer within, still
waited for, closed, failed with libvirt's text) were English f-strings;
they are messages now, each close reason a whole one. A connection
that died without a close callback raised an error reading "None"; it
now names the host. Logs keep the English text.
A user's quota counted each VM's running vCPUs, memory and disks, so a
larger value set for the VM's next start was not counted, and a clone
counted only once its VM was recorded, so a user could queue clones
past the quota. Now:
- Each VM counts the larger of its running and its next-start values.
- A clone job counts as one VM with the source's persistent vCPUs,
memory and disk size, which its plan stores, from its admission until
its VM is recorded; a failed, cancelled or resolved job no longer
counts. The clone's VM and its owner are recorded in one transaction,
so the quota counts either the job or the VM, never neither.
- The quota reads each VM's definition once (cached_reads).
- The Host devices tab gives a shut-off VM a PCI device of its host and
takes it back; libvirt binds the device to vfio-pci when the VM starts
and gives it back when it stops (managed). The VM's PCI devices are
listed with whether the running VM and its next start have them.
- A device is offered, and accepted on the server under the compute's
claim, only when it is no bridge of any kind (bridge header, PCIe port,
or of the bridge class: host bridge, LPC), the host has none of its own
network interfaces, disks or graphics card on it (else: bind it to
vfio-pci on the host first), no other VM names it, and every other
endpoint of its IOMMU group is the VM's too or has no driver or
vfio-pci and no other VM; bridges in the group stay with pcieport, and
a member that cannot be read keeps the group. Nothing in the group is
taken implicitly.
- A snapshot revert checks the PCI devices of the snapshot with the same
rules; migration and clones already leave host devices out.
- The add forms of the tab load together, when the tab opens.
- A Host devices tab on the VM page lists the VM's USB host devices, each
once: how it is chosen (its address, or any device of its model), the
device the running VM holds and whether its next start has it; its other
host devices (PCI, SCSI, mediated) are listed for the XML editor.
- Superusers add a USB device of the host and take it back, on a running
VM too. The add form is loaded when the tab opens, as its choices read
every VM of the host; a hub, a device the host has its own disks or
network interfaces on, or one another VM names is not offered, with the
reason, and refused on the server under the compute's claim. A device is
chosen by model when the host has one of it, else by its address.
- A VM without a USB controller is refused; a device is taken from each
definition as that definition describes it.
- A clone gets none of the VM's host devices (the clone form says so), and
a VM with host devices is not migrated. A snapshot revert is refused when
it would give the VM a device another VM names or the host uses.
- A NIC that is a host device is no longer edited or removed from the
Network tab: the XML editor changes it.
Disk sizes were pre-filled rounded to whole GiB, so a 3.5 GiB disk showed
4 and was grown, for good, whenever another disk was resized; an empty
field or a disk outside a pool was a 500. A disk's field is now empty with
its size as the placeholder: an empty field leaves the disk alone, a
larger whole number grows it, anything else is refused with a message.
vCPUs change only on a shut-off VM, also on a direct request: a running
VM got them at its next start, past the quota counted against its live
count. Current vCPUs or memory above the maximum are refused instead of
failing (and dropping vCPU hot-plug) or being capped by libvirt. A running
VM's maximum memory select is disabled, since its maximum is kept, and a
custom memory value is sent only while its box is ticked.
- An administrator could block, delete or demote (unset Active or
Superuser on) their own account, and with it the last one, leaving the
panel without anyone to undo it. These are now refused.
- The user form showed "No password set." for users who have one: its
password field never read the user's password. Its "Set password"
link went to ../password/, a page this panel does not have. The form
now says whether a password is set and links the page that sets it.
- "Staff status" said "can log into this admin site"; here it lets a
user change and delete the template VMs given to them, and is now
called Template editor.
- A quota of 0 counted as no limit, like -1, so a user's quota could not
be taken away. Now -1 has no limit and 0 allows none; the help says
so, and the labels give the units: memory in MiB, disk in GiB.
- A user's page for a user that does not exist answered with a server
error instead of not found.
- The user list said "None" for a user who never logged in; it says
"never", and dates fit their column.
- The password form's labels no longer break mid-word.
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.
131 test modules sat next to the code they test; instances alone had
51 of them beside views.py and utils.py. They move into a
tests/ package per app, and the JavaScript checks into
webvirtcloud/tests/js. Each non-empty tests.py becomes tests/test_views.py;
the empty generated stubs are removed.
Imports of the app's own modules become absolute, paths built from
__file__ go one level up, the live helper is instances.tests.livetest,
and coverage omits */tests/*. The suite discovers the same 960 tests as
before.
