Bhyve exit code 4 with PCI passthru

[Xavier Humbert]

Hi,

Cannot boot VM with PCI passthru enabled.

My /boot/loader.conf (relevant part):

vmm_load="YES"
nmdm_load="YES"
if_bridge_load="YES"
if_tap_load="YES"
pptdevs="10/0/0"
hw.vmm.amdvi.enable=1

My vm-bhyve config

loader="grub"
grub_run_partition="2"
cpu=2
memory=4096M
network0_type="virtio-net"
network0_switch="public"
disk0_type="virtio-blk"
disk0_name="disk0.img"
uuid="f878c150-de67-11ec-8816-d05099c11279"
network0_mac="58:9c:fc:0d:84:62"
disk1_name="disk1.img"
disk1_type="virtio-blk"
disk1_dev="file"
disk2_name="disk2.img"
disk2_type="virtio-blk"
disk1_dev="file"
passthru0="10/0/0"
bhyve_options="-w"

And the log :
