meta-virtualization
|
|
===================
|
|
|
|
The meta-virtualization layer is the authoritative resource for virtualization
|
|
technologies in OpenEmbedded / Yocto built distributions. It provides support
|
|
or both hypervisor-based virtualization (such as KVM, Xen, and QEMU) and
|
|
system-level virtualization (Linux containers), along with the host and guest
|
|
technologies required to build complete solutions ranging from embedded systems
|
|
to full deep CNCF stack deployments.
|
|
|
|
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 kubernetes 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.
