+6.10.3-EE and 6.10.0.1-CE release includes ARM64 packages for all supported operating systems.
+
+These ARM packages are being released in beta mode, allowing the community to test them and provide feedback. This initiative aims to extend OpenNebula’s flexibility by enabling deployment on ARM-based servers (both hypervisors and front-end nodes), opening new possibilities for lightweight, distributed cloud environments.

+ARM64 Specifics
+===============
+
+We suggest the following adjustments for the ARM64 architecture. In ``/etc/one/oned.conf``, switch to ``sd`` or ``vd`` for the CD-ROM device:
+
+.. code::
+
+    DEFAULT_CDROM_DEVICE_PREFIX = "sd"
+
+This is necessary as IDE disk support is usually missing in ARM64.
+
+Additionally, we recommend adding a virtio keyboard using the ``RAW`` attribute in ``/etc/one/vmm_exec/vmm_exec_kvm.conf`` to ensure keyboard functionality over VNC:
+
+.. code::
+
+    RAW = "<devices><input type='keyboard' bus='virtio'/></devices>"
+
+The following OS section is recommended for an ARM64 host template. Here, ``virt`` is typically an alias for the most recent ``QEMU ARM Virtual Machine``:
+
+.. code::
+
+   OS=[
+     ARCH="aarch64",
+     FIRMWARE="/usr/share/AAVMF/AAVMF_CODE.fd",
+     FIRMWARE_SECURE="no",

 By using KVM, you can run multiple Virtual Machines with unmodified Linux or Windows images. Each Virtual Machine has private virtualized hardware - network card, disk, graphics adapter, etc.
