Celery 5.x introduced a new worker argument format that is not
backwards-compatible with the older Celery 4.x format. This created a
conundrum since we use one service unit for both Debian 10 (4.x) and
Debian 11 (5.x). Instead of worse hacks, create a wrapper script to
start the worker with the correct arguments instead.
I can see no possible reason to want to do limits against UUIDs, but
supporting that means match is not what one would expect since a random
UUID could match the limit. So only limit based on the name.
With many VMs this slows down linearly. Rework it a bit so there are
fewer calls to getInformationFromXML and so the processing could happen
in parallel at some point.
Also fixes up the Debian packaging such that this works how I would
want, with proper module installation while leaving everything else
untouched. Finally implements automatic installation and removal of the
BASH completion for the PVC command.
Trying to do this on the VMInstance side had problems because we can't
differentiate the 3 types of migration there. So, just update this in
the API side and hope everything goes well.
This introduces an edge bug: if a VM is using a macvtap SR-IOV device,
and then tries to migrate, and the migrate is aborted, the NIC lists
will be inconsistent.
When I revamp the VMInstance in the future, I should be able to correct
this, but for now we'll have to live with that edgecase.
Done to make the resulting config match the expectations when using "vm
network add", which is that networks are below disks, not above.
Not a functional change, just ensures the VM XML is consistent after
many changes.
Ensures that the configuration of a VF is not overwritten in Zookeeper
on a node restart. The SRIOVVFInstance handlers were modified to start
with None values, so that the DataWatch statements will always trigger
updates to the live system interfaces on daemon startup, thus ensuring
that the config stored in Zookeeper is applied to the system on startup
(mostly relevant after a cold boot or if the API changes them during a
daemon restart).
Adds support for the node daemon managing SR-IOV PF and VF instances.
PFs are added to Zookeeper automatically based on the config at startup
during network configuration, and are otherwise completely static. PFs
are automatically removed from Zookeeper, along with all coresponding
VFs, should the PF phy device be removed from the configuration.
VFs are configured based on the (autocreated) VFs of each PF device,
added to Zookeeper, and then a new class instance, SRIOVVFInstance, is
used to watch them for configuration changes. This will enable the
runtime management of VF settings by the API. The set of keys ensures
that both configuration and details of the NIC can be tracked.
Most keys are self-explanatory, especially for PFs and the basic keys
for VFs. The configuration tree is also self-explanatory, being based
entirely on the options available in the `ip link set {dev} vf` command.
Two additional keys are also present: `used` and `used_by`, which will
be able to track the (boolean) state of usage, as well as the VM that
uses a given VIF. Since the VM side implementation will support both
macvtap and direct "hostdev" assignments, this will ensure that this
state can be tracked on both the VF and the VM side.
Adds configuration values for enabled flag and SR-IOV devices to the
configuration and sets up the initial SR-IOV configuration on daemon
startup (inserting the module, configuring the VF count, etc.).
