Bhyve exit code 4 with PCI passthru

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 :
