OpenBSD 7.6 amd64をLinuxのVirt-Manager上で動かしています．serialを有効にしてhostからvirsh consoleで繋げるようにしてみました．
初期状態ではディスク暗号化のアンロックやbootプロンプトは見えます．bootプロンプトでserialを有効にすることもできますが毎回やらないといけないので面倒です．
こちらのFAQを参考に設定しました．
ブートプロセスをserialへ(amd64/i386)
/etc/boot.conf に以下を追記set tty com0
ログインプロンプト以降のserial対応
/etc/ttys を編集して， tty00 からの行を書き換えます．
書き換え前
tty00 "/usr/libexec/getty std.9600" unknown off
書き換え後
tty00 "/usr/libexec/getty std.9600" vt220 on secure
Note | 9600部分はserial速度で，115200でも動作しました． |
これで次回以降serialが有効になり，virsh consoleで接続して利用できます．
