* On FreeBSD11+, the <tt>vt</tt> driver has replaced the <tt>sc</tt> console driver. So far as I am aware, the latter is necessary to use <tt>vidcontrol</tt> to change virtual screen resolution. Once <tt>kern.vty=sc</tt> is added to <tt>/boot/loader.conf</tt>, qemu using the <tt>-vga std</tt> arguments ought be able to do high resolution with e.g. <tt>vidcontrol MODE_401</tt> (1920x1080x24). Once the mode is verified, it can be set on boot by adding an e.g. <tt>allscreens_flags="MODE_401"</tt> line to <tt>/etc/rc.conf</tt>. | |||
* If your boot locks up, ensure you've provided <tt>-serial stdio</tt>. See [https://docs.netgate.com/pfsense/en/latest/troubleshooting/boot-issues.html#Booting_with_an_alternate_console Booting with an alternate console] at NetGate and [https://www.digitalocean.com/community/tutorials/how-to-recover-from-file-system-corruption-using-freebsd-s-single-user-mode Recovering File System Corruption] from DigitalOcean. | |||
