Re: [PATCH 2/2] qemu: Introduce the ability to disable the built-in PS/2 controller

A while back QEMU introduced a new machine option for disabling the i8042 PS/2 controller (commit 4ccd5fe22feb95137d325f422016a6473) which up until then was a built-in device included by all PC machine type descendants unconditionally. This new option allowed users to disable emulation of this controller, thus removing the default PS/2 peripherals. The rationale for why somebody might want to disable PS/2 peripherals is explained in the aforementioned commit. This introduces a new 'ps2' feature which, when disabled, results in no implicit PS/2 bus input devices being automatically added to the domain and addition of the 'i8042=off' machine option to the QEMU command-line. A notable side effect of disabling the i8042 controller in QEMU is that the vmport device won't be created. For this reason we will not allow setting the vmport feature if the ps2 feature is explicitly disabled.
