Hi Jerry,
The Linux Jailhouse (https://github.com/siemens/jailhouse) project is one means of implementing an AMP solution for x64. Does bhyve offers similar possibilities?
Yes, indirectly:
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)
For these type of use-cases, you would pin a guest to a single core, and use cpusets to prevent FreeBSD from running on that core. The
For these type of use-cases, you would pin the guest to a single core using the bhyve '-p' option, and use the cpuset command to prevent FreeBSD itself from running on that core.
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?
Stock PCI passthru works this way. later, Peter. _______________________________________________ freebsd-virtualization@freebsd.org mailing list https://lists.freebsd.org/mailman/listinfo/freebsd-virtualization To unsubscribe, send any mail to "freebsd-virtualization-unsubscr...@freebsd.org"
