Overriding hostname in a .conf file, via base-files:
HOST_NAME="k3s-host"
hostname_pn-base-files = "${HOST_NAME}"
Is always a valid option, but if it is not configured, we can easily
have two hosts with the same name on the network, confusing adddress
assignement, etc.
This commit introduces a way to generate a unique hostname based
on the uuid of the build host, and the machine being built.
If virt-unique-hostname is added to IMAGE_FEATURES, like the following:
IMAGE_FEATURES += "virt-unique-hostname"
IMAGE_FEATURES[validitems] += "virt-unique-hostname"
Then a rootfs postprocessing hook will override hostnae to something
unique.
Note: this means your image will be reproducible on a single builder,
but not between them.

Add a new minimal OEQA test case to run the Xen Test Framework
test runner in the standard testimage step. Tested with qemux86-64
and designed for compatibility with Arm when XTF supports it.
To enable, append to local.conf:
INHERIT += "testimage"
QEMU_USE_SLIRP = "1"
TEST_SERVER_IP = "127.0.0.1"
To run: bitbake -c testimage xtf-image
For inspection while it runs, at another shell prompt:
* Observe the image booting:
tail -f ${TMPDIR}/work/qemux86_64-*/xtf-image/*/testimage/qemu_boot_log.*
* Observe the tests running once boot has completed:
tail -f ${TMPDIR}/work/qemux86_64-*/xtf-image/*/temp/log.do_testimage
The XTF test sequence by default is a single XTF test case with minimal
hardware dependency to ensure that Xen is running, the Xen toolstack is
functional and XTF works. Additional XTF test cases for an image can be
configured via variables that are documented in the OEQA test case:
* XTF_TEST_CASES_POPULATE
* XTF_TEST_CASES_SKIP
* XTF_TEST_CASES_REQUIRE
Since testimage requires a functioning network to perform the tests on
the image and the qemu MACHINES do not have networking enabled
this commit provides a new qemuboot-testimage-network bbclass to add an
image postprocess command to enable a functional eth0 for qemu MACHINES.

OEcore/bitbake are moving to use the clearer ":" as an overrides
separator.
This is pass one of updating the meta-virt recipes to use that
syntax.
This has only been minimally build/runtime tested, more changes
will be required for missed overrides, or incorrect conversions
Note: A recent bitbake is required:

bitbake: data_smart/parse: Allow ':' characters in variable/function names
It is becomming increasingly clear we need to find a way to show what
is/is not an override in our syntax. We need to do this in a way which
is clear to users, readable and in a way we can transition to.
The most effective way I've found to this is to use the ":" charater
to directly replace "_" where an override is being specified. This
includes "append", "prepend" and "remove" which are effectively special
override directives.
This patch simply adds the character to the parser so bitbake accepts
the value but maps it back to "_" internally so there is no behaviour
change.
This change is simple enough it could potentially be backported to older
version of bitbake meaning layers using the new syntax/markup could
work with older releases. Even if other no other changes are accepted
at this time and we don't backport, it does set us on a path where at
some point in future we could
require a more explict syntax.
I've tested this patch by converting oe-core/meta-yocto to the new
syntax for overrides (9000+ changes) and then seeing that builds
continue to work with this patch.

The Xen hypervisor built for Arm 64-bit targets can be launched with
runqemu by providing a Device Tree binary and configuration for Qemu,
which enables interactive testing of Xen images.
Add qemuboot-xen-dtb.bbclass to add a new bitbake task for generating
the dtb file by using lopper on a device tree produced by Qemu.
Add qemuboot-xen-defaults.bbclass to supply working default parameters
for the qemuarm64 machine and general support for qemuboot for Xen,
and adjust the defaults as needed to boot successfully in testing.

As part of allowing different types of oci images to be created,
we split our IMG_cmd into .inc files that can then be specific to
the selected type.
For the umoci backend: We can take the same options as sloci
expects and use umoci to create images.
The resulting OCI image is similar, but by using umoci, we set
the stage to do multi-tag, or multi-layer images in the future.
But for now, we are functionally equivalent to the sloci backend.

The sdcard class in the meta-raspberrypi layer is now extensible with
support for adding files such as hypervisor binaries to the boot
partition, so this layer can switch to use that and drop the custom
sdcard bbclass.
Uses the new RPI_SDIMG_EXTRA_DEPENDS and DEPLOYPAYLOAD variables,
and: IMAGE_CLASS: sdcard_image-rpi-xen => sdcard_image-rpi
IMAGE_FSTYPE: rpi-xen-sdimg => rpi-sdimg
Please note that the filename suffix of the image is changed by this.
Also apply _raspberrypi4-64 scoping to the Raspberry Pi settings.

At the moment the regular meta-raspberrypi SD card class does not allow
for optional inclusion of extra files in the SD card boot partition
without requiring those same files be present in the root filesystem.
This affects hypervisor binaries, such as Xen, which do not necessarily
belong within the guest filesystem.
As a workaround, inherit the sdcard_image-rpi.bbclass and clone the
main IMAGE_CMD function, adding the Xen-specific deploy that is needed.
This can be retired when the parent class has extensibility added.

These settings are necessary for Xen and enabling them here, using the
same mechanism that is used by k8s in this layer, simplifies building
images for Xen.
- Ensure that Xen mode is enabled in QEMU.
- On ARM platforms: enable Flattened Device Tree (FDT) support.

We were using USER_CLASS loading to allow conditional checking
on DISTRO_FEATURES, which triggered distro feature specific version
pinning.
It was found that DISTRO_FEATURES set in local.conf is not
consistently available at layer.conf parse time, hence our checks
were not always working as expected (i.e. the version files are
not included).
If we move the DISTRO_FEATURE check to the bbclasses, and use it
to trigger the include, we should have a consistent set of variable
resolution and consistent behaviour.

As was reported:
https://lists.yoctoproject.org/g/meta-virtualization/message/4173?p=,,,20,0,0,0::Created,,conf%2Flayer.conf+is+broken,20,2,0,61269733
The conditional include of the meta-virt versions and config was not
working properly due to parse time constraints.
This commit fixes that by following the example of the meta-cube layer
and instead using a user bbclass to load the .inc file after
distro/distro features have been resolved by bitbake.

This image class creates an oci image spec directory from a generated
rootfs. The contents of the rootfs do not matter (i.e. they need not be
container optimized), but by using the container image type and small
footprint images, we can create directly executable container images.
Once the tarball (or oci image directory) has been created of the OCI
image, it can be manipulated by standard tools. For example, to create a
runtime bundle from the oci image, the following can be done:
Assuming the image name is "container-base":
If the oci image was a tarball, extract it (skip, if a directory is being directly used)
% tar xvf container-base-<arch>-<stamp>.rootfs-oci-latest-x86_64-linux.oci-image.tar
And then create the bundle:
% oci-image-tool create --ref name=latest container-base-<arch>-<stamp>.rootfs-oci container-base-oci-bundle
Or to copy (push) the oci image to a docker registry, skopeo can be used (vary the
tag based on the created oci image:
% skopeo copy --dest-creds <username>:<password> oci:container-base-<arch>-<stamp>:latest docker://zeddii/container-base
The following image variables are available to customize the details
of the constructed image (defaults as shown):
OCI_IMAGE_AUTHOR ?= "${PATCH_GIT_USER_NAME}"
OCI_IMAGE_AUTHOR_EMAIL ?= "${PATCH_GIT_USER_EMAIL}"
OCI_IMAGE_TAG ?= "latest"
OCI_IMAGE_RUNTIME_UID ?= ""
OCI_IMAGE_ARCH ?= "${TARGET_ARCH}"
OCI_IMAGE_SUBARCH ?= "${@oci_map_subarch(d.getVar('TARGET_ARCH'), d.getVar('TUNE_FEATURES'), d)}"
OCI_IMAGE_ENTRYPOINT ?= "sh"
OCI_IMAGE_ENTRYPOINT_ARGS ?= ""
OCI_IMAGE_WORKINGDIR ?= ""
//List of ports to expose from a container running this image:
//PORT[/PROT]
// format: <port>/tcp, <port>/udp, or <port> (same as <port>/tcp).
OICI_IMAGE_PORTS ?= ""
// key=value list of labels
OCI_IMAGE_LABELS ?= ""
// key=value list of environment variables
OCI_IMAGE_ENV_VARS ?= ""
