Hi,
here some more information:

rc.conf:
[...]
vm_enable="YES"
vm_dir="zfs:zroot/vm123"
iovctl_files="/etc/iov/ixl1.conf"

(VMs are not started automatically due to the problem, the issue is triggered
by manually starting the vm via "vm -f install ...")

debian9-test.conf:
--
loader="grub"
cpu=1
memory=4096M
disk0_type="ahci-hd"
disk0_name="disk0.img"
grub_run_partition="1"
grub_run_dir="/boot/grub"
passthru0="2/0/81"
--

pciconf -l 
[...]
ppt0 at pci0:2:0:81: ...


"vm passthru" output
