Improve debugging capabilities when Docker daemon fails to start: - Log dockerd output to /var/log/docker.log instead of /dev/null - Capture docker info exit code and output for diagnostics - Show docker info error on every 10th iteration while waiting - Include last docker info output and docker.log tail on failure - Extend sleep on failure from 2s to 5s for log review Signed-off-by: Bruce Ashfield <bruce.ashfield@gmail.com> |

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.
- vcontainer: enables vdkr/vpdmn virtual container runtime support, including kernel config fragments (9p, squashfs, overlayfs) and busybox utilities (base64, hexdump) required for container cross-install during image builds.
