Given that bge driver claimed 2/0/0, most likely vmm.ko failed to load or probably was not present. Do you have vmm_load=“YES” in /boot/loader.conf as mentioned in https://wiki.freebsd.org/bhyve/pci_passthru? <https://wiki.freebsd.org/bhyve/pci_passthru?>; If you already have loader.conf configured correctly, you can try to manually load vmm.ko once system is booted and see dmesg for any problem in loading it like kernel mismatch, missing symbol[One common I usually encounter is KTRACE define in sys/modules/vmm/Makefile but kernel config is missing “option KTRACE”] etc. Thanks, Anish > On Nov 28, 2014, at 5:05 PM, Craig Rodrigues <rodrigc@FreeBSD.org> wrote: > > On Fri, Nov 28, 2014 at 1:10 PM, Nikos Vassiliadis <nvass@gmx.com> wrote: > >> Hi, >> >> I am trying to use PCI passthrough to pass the bge device to a guest but I >> am doing something wrong.
