Libvirt Cloud Module
====================
Example provider:
.. code-block:: yaml
# A provider maps to a libvirt instance
my-libvirt-config:
driver: libvirt
# url: "qemu+ssh://user@remotekvm/system?socket=/var/run/libvirt/libvirt-sock"
url: qemu:///system
Example profile:
.. code-block:: yaml
base-itest:
# points back at provider configuration e.g. the libvirt daemon to talk to
provider: my-libvirt-config
base_domain: base-image
# ip_source = [ ip-learning | qemu-agent ]
ip_source: ip-learning
# clone_strategy = [ quick | full ]
clone_strategy: quick
ssh_username: vagrant
# has_ssh_agent: True
password: vagrant
# if /tmp is mounted noexec do workaround
deploy_command: sh /tmp/.saltcloud/deploy.sh
# -F makes the bootstrap script overwrite existing config
# which make reprovisioning a box work
script_args: -F
grains:
sushi: more tasty
# point at the another master at another port
minion:
master: 192.168.16.1
master_port: 5506
Tested on:
- Fedora 26 (libvirt 3.2.1, qemu 2.9.1)
- Fedora 25 (libvirt 1.3.3.2, qemu 2.6.1)
- Fedora 23 (libvirt 1.2.18, qemu 2.4.1)

This function determines whether or not
to make this cloud module available upon execution.
Most often, it uses get_configured_provider() to determine
if the necessary configuration has been set up.
It may also check for necessary imports decide whether to load the module.
In most cases, it will return a True or False value.
If the name of the driver used does not match the filename,
then that name should be returned instead of True.

Clean up clone domain leftovers as much as possible.
Extra robust clean up in order to deal with some small changes in libvirt
behavior over time. Passed in volumes and domains are deleted, any errors
are ignored. Used when cloning/provisioning a domain fails.
:param cleanup: list containing dictonaries with two keys: 'what' and 'item'.
If 'what' is domain the 'item' is a libvirt domain object.
If 'what' is volume then the item is a libvirt volume object.
Returns:
none

This function irreversibly destroys a virtual machine on the cloud provider.
Before doing so, it should fire an event on the Salt event bus.
The tag for this event is `salt/cloud/<vm name>/destroying`.
Once the virtual machine has been destroyed, another event is fired.
The tag for that event is `salt/cloud/<vm name>/destroyed`.
