BKK19-512 Xen Dom0-less
When developing embedded systems, it is common to have mixed-criticality requirements: one application is critical, and often comes with real-time requirements, while the other application is far less critical and it is typically based on Linux. Static partitioning is the best way to meet these requirements.

This talk will introduce Dom0-less: a brand 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. Dom0-less makes booting a critical application in less than a second an achievable goal. Xen userspace tools, such as xl and libvirt, become only optional. Even Dom0, the cardinal point of every Xen deployment since its inception, becomes inessential.

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 presentation will also include a live demo of the technology.
