Hello to everyone.

I want to show you what it seems to be a bug in bhyve. Please evaluate the
situation below :

/usr/sbin/./bhyve-win -S -c sockets=4,cores=2,threads=1 -m 8G -w -H \
-S -c sockets=4,cores=2,threads=1 -m 8G -w -H \
-s 0,hostbridge \
-s 1,ahci-hd,/mnt/$vmdisk0'p2'/bhyve/img/Windows/Windows11.img,bootindex=1 \
-s 2,ahci-hd,/dev/$vmdisk5 \
-s 8:0,passthru,2/0/0 \
-s 8:1,passthru,2/0/1 \
-s 8:2,passthru,2/0/2 \
-s 8:3,passthru,2/0/3 \
-s 13,virtio-net,tap18 \
-s 29,fbuf,tcp=0.0.0.0:5918,w=1600,h=950,wait \
-s 30,xhci,tablet \
-s 31,lpc \
-l bootrom,/usr/local/share/uefi-firmware/BHYVE_UEFI_CODE.fd \
vm0:18 < /dev/null & sleep 2 && vncviewer 0:18

as you can see I have attached all the slots of my GPU. Infact my Nvidia GPU
has 4 slots :

02:00.0 VGA compatible controller: NVIDIA Corporation TU102 [GeForce RTX 2080
Ti] (rev a1)
02:00.1 Audio device: NVIDIA Corporation TU102 High Definition Audio Controller
(rev a1)
02:00.2 USB controller: NVIDIA Corporation TU102 USB 3.1 Host Controller (rev
a1)
02:00.3 Serial bus controller: NVIDIA Corporation TU102 USB Type-C UCSI
Controller (rev a1)

As you can see my GPU has one USB controller and one USB port mini integrated
with the controller. Well,I attached a pen drive on the port of the USB
controller and then I tried to boot the Windows 11 vm. What's happened ?
that,despite I have declared that I want boot the Windows11 vm at slot 1 by
adding the parameter bootindex=1,instead,it booted from the USB stick attached
to the mini USB port of the USB controller (yes because on that USB stick I
have installed Windows 7,so it can boot). This seems to be a bug,because it
does not do what I want. And it is easy to reproduce. Just put bootindex=1 to
every OS that you want to boot and then attach a bootable USB stick to the usb
port of the GPU (it should be recent,it should be a GPU with the USB controller
integrated,but the latest high quality GPU models have it),and just run the
bhyve VM and you will see that it will not boot the OS you want.
