If a bhyve UEFI-booted guest is launched with a com1,stdio console, that console is useful as a system console on the VM, and in the case of Windows Server, the SAC management console. Unfortunately, the com1,stdio console receives various error reporting from bhyve, including keyboard/mouse and "rdmsr to register" notifications. Workaround: Use an nmdm or pty console device Desirable solution: Proper bhyve logging to a mechanism such as one or more log files or syslog.
I'm not sure if this is a bug. Bhyve, as a usual utility, displays the stderr on the terminal. Therefore, you can simply redirect stderr output to a file. # bhyve ... -l com1,stdio ... 2>vmerr.log # cat vmerr.log rdmsr to register 0x4e on vcpu 0 rdmsr to register 0x34 on vcpu 0 wrmsr to register 0xc8f(0) on vcpu 0 Unhandled ps2 mouse command 0xe1 Unhandled ps2 mouse command 0x88 Unhandled ps2 keyboard command 0xf6
That workaround is preferable to every suggestion to date. I don't know if grehan@ requested a ticket for another reason but I will mark this as resolved.
