Bug ID: 282240
Summary: A patch or something to allow bhyve to use virtio
1.0...
Product: Base System
Version: 14.1-RELEASE
Hardware: Any
OS: Any
Status: New
Severity: Affects Many People
Priority: ---
Component: bhyve

Hello.
I'm trying to use the virtio-input parameter in bhyve to share one of my mouses
within a Linux vm :
From “man bhyve”
(https://www.freebsd.org/cgi/man.cgi...FreeBSD+14.0-CURRENT&arch=default&format=html):
Virtio input device backends:
/dev/input/eventX
Send input events of /dev/input/eventX to guest
by VirtIO Input Interface.
Ok,I tried on my FreeBSD system :
[marietto@marietto ~]==> sudo libinput debug-events

The USB mouse that I want to pass is this :
-event9 DEVICE_ADDED vendor 0x04b3 USB Optical Mouse, class 0/0,
rev 2.00/2.00, addr 26 seat0 default group10 cap:p left scroll-nat
scroll-button
so,between the bhyve parameters I've added ---> "-s
10,virtio-input,/dev/input/event9"
/usr/sbin/./bhyve-lin -S -c sockets=2,cores=2,threads=2 -m 4G -w -H -A \
-s 0,hostbridge \
-s 1,ahci-hd,/mnt/zroot2/zroot2/bhyve/img/Linux/Ubuntu2410.img,bootindex=1 \
-s 3,nvme,/dev/nda0 \
-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 9,passthru,1/0/0 \
-s 10,virtio-input,/dev/input/event9 \
-s 13,virtio-net,tap1 \
-s 14,virtio-9p,sharename=/ \
-s 29,fbuf,tcp=0.0.0.0:5901,w=1600,h=950,wait \
-s 30,xhci,tablet \
-s 31,lpc \
-l bootrom,/usr/local/share/uefi-firmware/BHYVE_UEFI_CODE.fd \
vm0:1 < /dev/null & sleep 2 && vncviewer 0:1
Unfortunately inside Ubuntu 24.04 the "0x04b3 USB Optical Mouse" does not move
at all. The reason is that bhyve only uses the virtio 0.9 protocol yet.
Unfortunately, Linux requires virtio 1.0. Can someone create a patch to allow
bhyve to use virtio 1.0 ? thanks.
