Michal Orzel a2dd7d887f xen: Disable highmem on qemuarm
By default, highmem option is enabled for machine types later than
virt-2.12. This allows qemu to place devices and RAM in physical
address space above 32-bits. This can cause issues as according to the
documentation Xen supports up to 12GiB of physical address space.
Recently the issue was observed using runqemu, that was causing Linux
running on top of Xen to stall when trying to access ECAM space placed
by qemu at 256GiB mark. Even though this issue is most probably related
to QEMU and not Xen (the investigation showed that it can map ECAM
space correctly), it is best to avoid such issues by disabling highmem
on qemuarm.

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.
