cede7fff8b Ensure XML diff output if not fully applied (#1576)
Make sure to perform a diff of the actual XML strings and not the object
representations if encountering the bug where the XML failed to be
updated correctly.

439830b6d4 Switch to xml-simple for document comparison (#1567)
The switch to compare-xml exhibits non intuitive behaviour in that
comparing without use of verbose mode does not detect documents that are
identical. The if statement allowed the tests to pass but reads that if
the documents compare as true then emit an error message and raise an
exception. However this is because it returns false even with the docs
are the same content. Unfortunately there was no pre-existing test
case added when

Since there were concerns about equivalent-xml not being active upstream
raised by a distribution maintainer, switching back should be avoided.
Attempted use of nokogiri-diff indicated that whitespace changes would
be treated as differences with it being unclear how to easily exclude.

Moving to xml-simple, which although will treat whitespace as
significant and even with NormaliseSpace set to disregard any whitespace
around content elements, it requires walking the returned structure to
remove the empty content attribute that is left behind to allow a direct
comparison between the data structures.

To ensure the XML comparison is validated add a test where libvirt
returns XML that is different to what was requested, and assert that
the expected error is raised, an error message emitted and that the
domain define would be reverted to the previous state if possible.

fc5598ddb8 Use equivalent-xml to compare xml (#1564)
Using diffy alone is insufficient to spot when the XML returned by
libvirt for the changes applied is equivalent but formatted differently.

When libvirt returns slightly differently formatted XML corresponding to
what changes were actually applied, it can result in an error being
assumed to have happened when the update actually worked as expected.

Equivalent-xml handles detecting XML documents as being identical,
therefore switching to using it instead of diffy should produce more
reliable results, while retaining diffy for better formatted diffs
should an issue occur is useful.

c7bcb50b2b Avoid domain undefine on configuration update (#1496)
Calling undefine on a domain and recreating it can result in some edge
case errors where if the current capabilities of libvirt have been
reduced, it may not be possible to restore the old definition.

Instead switch to calling `domain_define` with the new definition and
check that the resulting libvirt domain definition has been updated in
the expected manner, otherwise report an error to the user.

f498f102e1 Ensure updating loader tag supported (#1494)
The loader tag is required when nvram is being enabled. Ensure it is
marked as a requirement of validation and also support it's
configuration during the start domain action.

e4122f480a Use instance doubles for driver where possible (#1491)
Switch to instance doubles for driver where possible and reduce usage of
allow_any_instance_of.

Additionally replace some incorrect allows with expects to validate
calls are not made.

c4fcfee510 Set undefine flags to keep NVRAM (#1329)
Handle enabling and disabling of NVRAM during start domain.

This patch contains latent support for upstream PR fog-libvirt#102 to support destroy
with NVRAM enabled once that is merged.

Fixes #1027.

0756362b84 Output XML elements to debug logs (#1345)
Because libvirt may handle updating the XML of components differently
across different versions and user environments, add the generated
contents to the debug log to assist in understanding what is happening
for different users.

1251189145 Add ability to use emulated tpm (#1166)
Qemu has supported tpm 2 and the ability to start swtpm. Additionally 
it expands the tests for the tpm configuration to ensure that only when 
the options cause a change to the domain XML will the domain be updated 
on a subsequent start. This change just allows passing through the 
necessary config.

Vagrant.configure("2") do |config|
  config.vm.provider :libvirt do |libvirt|
    libvirt.tpm_model = "tpm-crb"
    libvirt.tpm_type = "emulator"
    libvirt.tpm_version = "2.0"
  end
end

21f7a796ff Reduce start domain unnecessary domain redefines (#1178)
Various checks in the start domain action were accidentally causing a
redefine right after initial create. Update to provide debug output when
the domain needs to be changed to allow capture of the redefines
occurring in the future and to make it easy for the tests to pick up
where the redefine was triggered by setting an expectation on the log
output.

Include a small fix to avoid running strip on what might be a nil object
returned for elements without any text attributes.

Fix a bug where changes to tpm settings made to the config after an
initial domain creation where there was previously no tpm defined, would
be ignored.

Adds a logger double and updates other tests that trigger log calls.
