What I want to achieve is to pass thru two of my NTFS "formatted" disks to a
Windows 11 VM,but without passing them thru using the USB controller in FreeBSD
with a bhyve virtual machine (in the example below I tried to boot Windows 11
from the nvme disk nvd0.
I've configured the bhyve VM like this :
bhyve -S -c sockets=1,cores=2,threads=2 -m 4G -w -H -A \
-s 0,hostbridge \
-s 1,ahci-hd,/dev/nvd0 \
-s 2,virtio-blk,/dev/da4p2 \
-s 3,virtio-blk,/dev/da2p1 \
-s 8,virtio-net,tap4 \
-s 10,hda,play=/dev/dsp,rec=/dev/dsp \
-s 29,fbuf,tcp=[0.0.0.0:5904](http://0.0.0.0:5904/),w=1440,h=900 \
-s 30,xhci,tablet \
-s 31,lpc \
-l bootrom,/usr/local/share/uefi-firmware/BHYVE_BHF_CODE.fd \
vm4 < /dev/null & sleep 2 && vncviewer 0:4
These are the NTFS disks that I would like to see inside the Windows 11 guest
os :
-s 2,virtio-blk,/dev/da4p2 \
-s 3,virtio-blk,/dev/da2p1 \
=> 34 19532873661 da4 GPT (9.1T)
34 32734 1 ms-reserved (16M)
32768 19532838912 2 ms-basic-data (9.1T)
19532871680 2015 - free - (1.0M)
=> 34 23437705149 da2 GPT (11T)
34 2014 - free - (1.0M)
2048 23437701120 1 ms-basic-data (11T)
23437703168 2015 - free - (1.0M)
I've tried also like this :
bhyve -S -c sockets=1,cores=2,threads=2 -m 4G -w -H -A \
-s 0,hostbridge \
-s 1,ahci-hd,/dev/nvd0 \
-s 2,virtio-blk,/dev/da4 \
-s 3,virtio-blk,/dev/da2 \
-s 8,virtio-net,tap4 \
-s 10,hda,play=/dev/dsp,rec=/dev/dsp \
-s 29,fbuf,tcp=[0.0.0.0:5904](http://0.0.0.0:5904/),w=1440,h=900 \
-s 30,xhci,tablet \
-s 31,lpc \
-l bootrom,/usr/local/share/uefi-firmware/BHYVE_BHF_CODE.fd \
vm4 < /dev/null & sleep 2 && vncviewer 0:4
and I get this error :
Assertion failed: (n >= 2 && n <= BLOCKIF_IOV_MAX + 2), function
pci_vtblk_proc, file /usr/src/usr.sbin/bhyve/pci_virtio_block.c, line 324.
I have also opened a bug request below,but no one replied until now.
Use nvme or ahci-hd for da4/da2 and see what you get. The whole disk needs to
go in there so Windows sees the GPT label. The other thing that comes to mind
is that FreeBSD has hold of the disks and won’t allow them to be inserted,
similar to issues when passing zvol into guests when volmode<>dev.
Cheers,
Jason.
