Windows Server in BHyve: mouse and keyboard doesn't works

[extrowerk]

Hi,

I wanted to install a recent Windows Server version in a bhyve zone, but mouse and keyboard doesn't works in recent Windows versions. LPC is already 31.

Versions I have tested:

Windows 2025 +updates till february 2026:  mouse : keyboard doesn't works.
Windows 2022 +updates till february 2026:  mouse : keyboard doesn't works.
Windows 2019 : works just fine

It seems BHyve emulates a PS2 mouse + keyboard. Can this be the culprit?

OS:

SunOS omnios 5.11 omnios-r151056-1acbca4f5bd i86pc i386 i86pc

Zone config in zadm, where I have attempted to add the "xhci-mouse" node as I have seen in a FreeBSD forum. I think it didn't helps.
