Per the bug mentioned upstream, grub2-mkconfig will currently not set the kernel options for BLS entries prefixed with a machine-id different to the running system. This affects the centos element, as the upstream .qcow2 comes with a pre-existing BLS entry but a blank machine-id. This only affects 9-stream -- prior releases either don't use BLS or have entries configured to use a common variable from grubenv which is updated correctly. We currently can not end-to-end test this in OpenDev because we run our functional tests on Ubuntu Focal (they use devstack), whose kernel can not read the XFS format on the 9-stream .qcow2. This expands the functional tests (that run on Debian Buster, with a later kernel) to add the vm element, so the bootloader path is exercised (this requires a block-device too). This at least runs the bootloader install, we can confirm the kernel options look right from the dumping provided the logs. Change-Id: I327f5e7a95e47905c01138c8c4483f3f03e8efff |

Environment Variables
---------------------
DIB_DISTRIBUTION_MIRROR:
:Required: No
:Default: None
:Description: To use a CentOS Yum mirror, set this variable to the mirror URL
before running bin/disk-image-create. This URL should point to
the directory containing the ``7/8/8-stream`` directories.
:Example: ``DIB_DISTRIBUTION_MIRROR=http://amirror.com/centos``
DIB_CLOUD_IMAGES:
:Required: No
:Description: Set the desired URL to fetch the images from. ppc64le:
Currently the CentOS community is working on providing the
ppc64le images. Until then you'll need to set this to a local
image file.
:Example: ``DIB_CLOUD_IMAGES=/path/to/my/centos/8/CentOS-8-GenericCloud-x86_64.qcow2``
