Greetings. I am exploring various possibilities for hard real time machine control running on dedicated x64 processors. The Linux Jailhouse (https://github.com/siemens/jailhouse) project is one means of implementing an AMP solution for x64. Does bhyve offers similar possibilities? In this case the guest can be viewed as a single threaded for(;;) loop that polls the USB3 controller, with the guest locked to a single core etc. (Practically, effectively I think, a subset of the ELF loader code in the fork here: https://github.com/g40/bhyveosvload) The key question, I think, revolves around PCI passthru capabilities. Is it possible to isolate and map specific hardware into the guest whilst running under the hypervisor? In this case it would be highly advantageous _not_ to virtualize the XHCI controller but I am not sure if this can be done within bhyve? I may be way off base here in which case I'll beg your collective indulgence. Any comments on this much appreciated. TIA Jerryhome | help
