Tested now with the generated fallback config in an lxc container.
Had to change to return a config rather than a network state.
Also this makes nocloud look in nocloud-net's seed dir.
This way it will read the seed and clame the datasource but
not do anything other than apply networking and the init_modules early.
It is a change in behavior of the time that boothooks woudl run to do
this. May need to change that back.

there is no data source that has a populated network_config()
so at this point this doesn't do anything.

on interfaces with characters between their numbers
|
|
I plan to re-use these methods later. They stand alone even if they
dont end up getting used, though.

'version' keys
|
|
- Removed systemd .link file generation, as it is not needed right now
- Changed return of generate_fallback_config to be just ns dict
- In distros.debian don't attempt to write .link file

configuration to be run if there is no network configuration provided by the
datasource.
NOTE: the code added here will not behave correctly if a net datasource has
network configuration. this code is temporary and should be reverted once
support for network configuration for net datasources after retrieving
config is in place.
based on: http://paste.ubuntu.com/15443576/
With this in place cloud-init properly chooses a fallback interface, configures
it and brings it online

not to attempt renaming the network interface to the default interface. Default
interface is controleld by net.DEFAULT_PRIMARY_INTERFACE and is currently set
to eth0 for legacy reasons. By default cloud-init will not attempt to rename
the device as this does not work in some situtations depending on the backing
driver of the device.

try/except blocks because there are sometimes read errors on the files and this
should not cause a stacktrace

distros base, and apply_fallback_network to distros to call
_write_network_fallback. Note that since _write_network_fallback is only
implemented for debian and ubuntu a check is needed to ensure that it does not
break behaviour for other distros.
Added function to disable .cfg files to util, since it may be useful elsewhere

This adds a check in cloud-init to see if the existing (cached)
datasource is still valid. It relies on support from the Datasource
to implement 'check_instance_id'. That method should quickly determine
(if possible) if the instance id found in the datasource is still valid.
This means that we can still notice new instance ids without
depending on a network datasource on every boot.
I've also implemented check_instance_id for the superclass and for
3 classes:
DataSourceAzure (check dmi data)
DataSourceOpenstack (check dmi data)
DataSourceNocloud (check the seeded data or kernel command line)

on in the event that no network configuration was provided to cloud-init
- Devices in /sys/class/net aside from loopback devices are scanned
- Each device is tested to determine if it has a carrier using
/sys/class/net/DEV/carrier, devices which do are preferred as they are most
likely connected to the outside world
- Devices which do not have a carrier but which might still be connected due
to being in a dormant or down state are used as fallbacks in case no
devices are found which have a carrier
- A network state dictionary is generated to be passed to
render_network_state to write ENI
- A systemd link file is generated that will rename the chosen device to eth0

Added code to customize timezone.
Added few utility functions to send events to the VMware hypervisor.
Re-factored the code little bit.
Added code to send SUCCESS event when customization succeeds.
Added code to send FAILED event if any error occurs during customization.

parsing the command line parameters returned a dictionary
but _merge_new_seed was expecting a string to be yaml loaded.
Change is to make _merge_new_seed take either string or dict.

Previously we returned a string of "." the same length as the dmi field.
That seems confusing to the user as "." would seem like a valid response
when in fact this value should not be considered valid.
So now, in this case, return empty string.

- Now my branch is identical to trunk.dist

this adds the consumption of 'network-config' to the datasourcenocloud.
There is an implementation of the network rendering taht is untested
in distros/debian.

it is not uncommon to find dmi data in /sys full of 'ff'. utf-8
decoding of those would fail, causing warning and stacktrace.
Return '.' instead of \xff. This is what dmidecode would return.
$ dmidecode --string system-product-name
|
|
at this point, this works:
python -m cloudinit.net.network_state examples/network-all.yaml
|
|
just add curtin/net as cloudinit/net
and then copy curtin/udev.py as cloudinit/net/udev.py

This add 'lxd' to the list of groups that the default user is added to.
It also changes behavior to create any necessary groups that are listed
for the user rather than failing to add the user.
Theres also a fix for usage of logexc that I found along the way.

- Added a new utility method to send a RPC for enabling NICS
- Modified DataSourceOVF.py to enable nics.
- Executed ./tools/run-pep8 and no issues were reported.
|
|
- Added few utility functions to report events to the underlying
VMware Virtualization platform
- Re-factored code little bit.
- Executed ./tools/run-pep8 and no pep8 errors were reported.

The user can still choose to run pollinate here to seed their
random data. And in an environment with network datasource, that
would be expected to work. However, we do not want to run it any
more from cloud-init because
a.) pollinate's own init system jobs should get it ran before ssh,
which is the primary purpose of wanting cloud-init to run it.
b.) with a local datasource, there is no network guarantee when
init_modules run, so pollinate -q would often cause issues then.
c.) cloud-init would run pollinate and log the failure causing
many cloud-init specific failures that it could do nothing about.
Additionally, add documentation for the seed_random config module.
