Users are allowed to set a LIBVIRT_DEFAULT_URI environment variable that
controls tools (i.e. virsh, virt-install, etc) that communicate with
libvirt. Let's allow for that mechanism to be used here.
Test settings modifying the `@uri` and `@qemu_use_session` variables to make
it easier to update and perform an initial minor refactor to reduce some
of the code currently in use to set `@uri`.
Commonly found in other Vagrant providers, a MAC address format without
colon delimiters is now accepted for better cross-compatibility of
Vagrantfiles.
assert_invalid was previously only raising an error if there was a
validation error logged, rather than if there wasn't an error. Tests
that expected validation failures were passing without any validation
errors being logged.
Move device assignment for CDROM's and disk storage to occur during
finalize, to ensure that storage config blocks are merged before
assigning devices.
This ensures that defining multiple storage config blocks within the
same or different Vagrantfiles that are merged, works as expected to
create multiple separate storage devices without needing to explicitly
define the dev name.
Fixes#655
Some simple spec tests to ensure validate and finalize work, which also
includes some tests showing that merging is not functioning as needed
for disks/cdroms both in cdroms not being merged across configs and
device ids are not handled correctly for merged configs.
