[-- Attachment #1 --] Hello. 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'm using this FreeBSD version : FreeBSD marietto 13.0-RELEASE FreeBSD 13.0-RELEASE #8 n244809-dff3dead3734: Wed Feb 23 13:16:32 CET 2022 marietto@marietto:/usr/obj/usr/src/amd64.amd64/sys/GENERIC amd64 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) As you can see I've used the virtio-blk driver,so inside the Windows 11 VM I've installed the latest version of the virtio drivers. The disks attached are 0 byte large,so they aren't recognized by Windows 11. Is this a bug or what ? They are USB 3.0 disks.
