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.

meta-virtualization
|
|
===================
|
|
|
|
This layer provides support for building Xen, KVM, Libvirt, and associated
|
|
packages necessary for constructing OE-based virtualized solutions.
|
|
|
|
The bbappend files for some recipes (e.g. linux-yocto) in this layer need to
|
|
have 'virtualization' in DISTRO_FEATURES to have effect. To enable them, add
|
|
in configuration file the following line.
|
|
|
|
DISTRO_FEATURES:append = " virtualization"
|
|
|
|
If meta-virtualization is included, but virtualization is not enabled as a
|
|
distro feature a warning is printed at parse time:
|
|
|
|
You have included the meta-virtualization layer, but
|
|
'virtualization' has not been enabled in your DISTRO_FEATURES. Some bbappend files
|
|
may not take effect. See the meta-virtualization README for details on enabling
|
|
virtualization support.
|
|
|
|
If you know what you are doing, this warning can be disabled by setting the following
|
|
variable in your configuration:
|
|
|
|
SKIP_META_VIRT_SANITY_CHECK = 1
|
|
|
|
Depending on your use case, there are other distro features in meta-virtualization
|
|
that may also be enabled:
|
|
|
|
- xen: enables xen functionality in various packages (kernel, libvirt, etc)
|
|
- kvm: enables KVM configurations in the kernel and autoloads modules
|
|
- k8s: enables kubernets configurations in the kernel, tools and configuration
|
|
- aufs: enables aufs support in docker and linux-yocto
|
|
- x11: enable xen and libvirt functionality related to x11
|
|
- selinux: enables functionality in libvirt and lxc
|
|
- systemd: enable systemd services and unit files (for recipes for support)
|
|
- sysvinit: enable sysvinit scripts (for recipes with support)
|
|
- seccomp: enable seccomp support for packages that have the capability.
