Re: Virtio-win driver (virtio-blk and virtio-scsi) don't work when they are used on bhyve with Windows 11 as guest os

I've just installed the virtio driver version suggested by Corvin (0.185)
and it works fine in Windows. So,now I can pass those NTFS disks without
using the USB controller. That's so cool. Bhyve becoming even more and more
interesting. I'm happy thanks to everyone. It works even in Linux without
passing the disks using the USB controller. Maybe I can make a lighter
/boot/loader.conf file,excluding the USB controllers.....
