This talk will introduce Dom0-less: a new way of using Xen to build mixed-criticality solutions. Dom0-less is a Xen feature that adds a novel approach to static partitioning based on virtualization. It allows multiple domains to start at boot time directly from the Xen hypervisor, decreasing boot times dramatically. Xen userspace tools, such as xl and libvirt, become optional.

Dom0-less extends the existing device tree based Xen boot protocol to cover information required by additional domains. Binaries, such as kernels and ramdisks, are loaded by the bootloader (u-boot) and advertised to Xen via new device tree bindings.

The audience will learn how to use Dom0-less to partition the system. Uboot and device tree configuration details will be explained to enable the audience to get the most out of this feature. The talk will include a status update and details on future plans.
