2021-03-08net: exclude OVS internal interfaces in get_interfaces (#829)Daniel Watkins
`get_interfaces` is used to in two ways, broadly: firstly, to determine the available interfaces when converting cloud network configuration formats to cloud-init's network configuration formats; and, secondly, to ensure that any interfaces which are specified in network configuration are (a) available, and (b) named correctly. The first of these is unaffected by this commit, as no clouds support Open vSwitch configuration in their network configuration formats. For the second, we check that MAC addresses of physical devices are unique. In some OVS configurations, there are OVS-created devices which have duplicate MAC addresses, either with each other or with physical devices. As these interfaces are created by OVS, we can be confident that (a) they will be available when appropriate, and (b) that OVS will name them correctly. As such, this commit excludes any OVS-internal interfaces from the set of interfaces returned by `get_interfaces`. LP: #1912844
2020-11-23Ability to hot-attach NICs to preprovisioned VMs before reprovisioning (#613)aswinrajamannar
Adds the ability to run the Azure preprovisioned VMs as NIC-less and then hot-attach them when assigned for reprovision. The NIC on the preprovisioned VM is hot-detached as soon as it reports ready and goes into wait for one or more interfaces to be hot-attached. Once they are attached, cloud-init gets the expected number of NICs (in case there are more than one) that will be attached from IMDS and waits until all of them are attached. After all the NICs are attached, reprovision proceeds as usual.

2020-05-14cloudinit: minor pylint fixes (#360)Daniel Watkins
We recently discovered that pylint is failing to report some errors when invoked across our entire codebase (see https://github.com/PyCQA/pylint/issues/3611). I've run pylint across every Python file under cloudinit/[0], and this commit fixes the issues so-discovered. [0] find cloudinit/ -name "*.py" | xargs -n 1 -t .tox/pylint/bin/python -m pylint

2018-11-29azure: detect vnet migration via netlink media change eventTamilmani Manoharan
Replace Azure pre-provision polling on IMDS with a blocking call which watches for netlink link state change messages. The media change event happens when a pre-provisioned VM has been activated and is connected to the users virtual network and cloud-init can then resume operation to complete image instantiation.
