Hello. I'm going to ask another question about the behavior,because I want to understand if I'm dealing with a bug or with a regular method of working. So,please be patient with me. 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 #5 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. You can see what's the problem by taking a look at the images below. They are 0 byte large,so they aren't recognized by Windows 11. Is this a bug or what ? I've also used the ahci-hd driver but I've got the same result. They are USB 3.0 disks. [image: 1.jpg] [image: 2.jpg] I've tried also : *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've got this error : *Assertion failed: (n >= 2 && n <= BLOCKIF_IOV_MAX + 2), function pci_vtblk_proc, file /usr/src/usr.s bin/bhyve/pci_virtio_block.c, line 324.* and I have also used the virtio-scsi driver 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-scsi,/dev/da4 \ -s 3,virtio-scsi,/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've installed the scsi driver taking it from this virtio iso file : *https://fedorapeople.org/groups/virt/virtio-win/direct-downloads/archive-virtio/virtio-win-0.1.215-1/virtio-win-0.1.215.iso <https://fedorapeople.org/groups/virt/virtio-win/direct-downloads/archive-virtio/virtio-win-0.1.215-1/virtio-win-0.1.215.iso> * and I have also installed the virtio-scsi driver,that has been accepted by windows,but the disks aren't recognized : it has been accepted by windows,but the disks aren't recognized : [image: 3.jpg] [image: 4.jpg] There are clearly various bugs to fix.
