Oleksii Kurochko 15e9fc23ec lxc: Backport patch that renames memfd_create() function
When Autotools makes configuration of LXC, the check of
the memfd_create() function fails because __stub_memfd_create and
__stub___memfd_create (The GNU C library defines this for functions
which it implements to always fail with ENOSYS) are defined in Glibc,
which leads to the fact that the macro HAVE_MEMFD_CREATE is not
defined and LXC provides defintion of the memfd_create() function as
static inline which in turn conflicts with a definition from
the <bits/mman-shared.h> file and causes an error:
| In file included from ../../../lxc-3.2.1/src/lxc/conf.c:79:
| <src_path>//lxc/syscall_wrappers.h:77:19: error: static declaration
| of 'memfd_create' follows non-static declaration
| | static inline int memfd_create(const char *name, unsigned int flags) {

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)
