The hypervisor and miniOS boots up in Mainstone/QEMU and soon on a Colibri/PXA270 board. EmbeddedXEN is mainly devoted to integrate multiple kernels into a single binary image for embedded systems with the support of hard realtime (domainU-RT, a new kind of Xen domain). Interesting, will have a look (again). Last time I checked was two years ago when MontaVista (IIRC) announced it. Does/will this version Xen not suffer from the RT problems Xen upstream has, e.g. lacking preemptibility? And what will be the impact on Xenomai? A new sub-arch per real arch? Will Xenomai run stand-alone or together with a Linux kernel as on real silicon? In the former case, what will be the programming model, specifically regarding RT<->non-RT communication?
