Hello,

I am wrapping my head around an issue with bhyve and a Windows Server 2022 guest I need to install.
I am running latest Smartos, but for easier debugging I start bhyve in the GZ using the following script:
----------------------------------------------------------------------------------------
#!/bin/sh
bootrom=/usr/share/bhyve/uefi-rom.bin
WINDOWS_INSTALL_CD=/zones/iso/server2022.iso
VIRTIO_DRIVER_CD=/zones/iso/virtio-win-0.1.262.iso
[ "$1" = "-k" ] || pfexec bhyvectl --vm=windows --destroy
bhyve -H -w \
        -s 0,hostbridge,model=i440fx \
        -B "1,product=SmartOS HVM" \
        -l bootrom,$bootrom \
        -l com1,stdio \
        -c 2 \
        -m 4G \
        -s 6:0,virtio-net-viona,vnic0 \
        -s 6:1,ahci-cd,$VIRTIO_DRIVER_CD \
        -s 4:0,ahci-cd,$WINDOWS_INSTALL_CD  \
        -s 5:0,nvme,/dev/zvol/rdsk/zones/a7ed5287-5b0f-4004-a6d5-0360c1964bcd-disk0 \
        -s 28,fbuf,vga=off,tcp=0.0.0.0:5801,w=1024,h=768,wait \
        -s 29,xhci,tablet \
        -s 31,lpc \
        windows
--------------------------------------------------------------------------------------------------------
I connect using vnc to port 5801, windows boots from the iso and the setup starts asking for language and such, but I cannot use mouse or keyboard to continue.
Doing the very same on the same system with a Server 2019 iso works as expected.
Any ideas where to look at?

thx

After several test on different hardware platfoms I believe I found a pattern:

- Win10, Server 2019 vnc input works as expected, both Intel or AMD hardware
- Win11, Server 2022 and 2025  vnc input works as expected on AMD platforms
- Win11, Server 2022 and 2025 vnc input does not work on any Intel platforms I tested

Here is stripped down version of my above startup script, requiring only a server2022.iso in case somebody wants to confirm/deny my findings:

#!/bin/sh
bootrom=/usr/share/bhyve/uefi-rom.bin
WINDOWS_INSTALL_CD=/zones/iso/server2022.iso
[ "$1" = "-k" ] || pfexec bhyvectl --vm=windows --destroy
bhyve -H -w \
        -s 0,hostbridge,model=i440fx \
        -B "1,product=SmartOS HVM" \
        -l bootrom,$bootrom \
        -l com1,stdio \
        -c 2 \
        -m 4G \
        -s 4:0,ahci-cd,$WINDOWS_INSTALL_CD  \
        -s 28,fbuf,vga=off,tcp=0.0.0.0:5801,w=1024,h=768,wait \
        -s 29,xhci,tablet \
        -s 31,lpc \
        windows

thx

dmesg shows something when starting the above script, maybe relevant here?
