Re: VNC Viewer on Windows: Unable to access VMs GUI

Hello my friend Odhiambo,
you can try to pass your keyboard and mouse to a specific USB to pci
adapter,using an USB splitter to attach both the input devices. Actually
I'm using the one integrated on my nvidia gpu,RTX 2080 ti,that's :
02:00.0 VGA compatible controller: NVIDIA Corporation TU102 [GeForce RTX
2080 Ti]
02:00.1 Audio device: NVIDIA Corporation TU102 High Definition Audio
Controller
*02:00.2 USB controller: NVIDIA Corporation TU102 USB 3.1 Host Controller*
02:00.3 Serial bus controller: NVIDIA Corporation TU102 USB Type-C UCSI
Controller
For sure you will add the PCI address of the board between your bhyve
parameters,for example in my case :
-s 8:2,passthru,2/0/2 \
A single hardware solution would be a pcie riser which splits the pcie port.
I've asked for a good USB controller some time ago :
https://forums.freebsd.org/threads/im-looking-for-a-good-usb-controller-3-0-4-ports-self-powered-compatible-with-freebsd.83323/
If it’s only mouse and keyboard you could use bhyves virtio-input emulation.
Corvin included virtio-input support in his github.
He committed virtio-input to 13.2 and 14.0 upstream.
From “man bhyve”
https://www.freebsd.org/cgi/man.cgi?query=bhyve&apropos=0&sektion=8&manpath=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.
