after many hours of trial and error this is now working:
debug=“yes"
loader="uefi"
uefi_vars="yes"
cpu=2
memory=32G
virt_random="yes"
network0_type="virtio-net"
network0_switch="public"
disk0_type="virtio-blk"
disk0_name="/dev/zvol/h/bhv-02"
disk0_dev="custom"
uuid="86b8741f-7764-11f1-8266-b8ca3aee713a"
network0_mac="58:9c:fc:00:6c:88"
graphics="yes"
graphics_res="1024x768"
grafics_wait="yes"
graphics_listen="0.0.0.0:5901”
and changing the filename in my dhcp i can boot diskless or local root.
the efi partition is empty, so it’s getting the bootrom from /usr/local/share/…
from the logs:
