From 71dc05635983ae711694f748d006e107387f1bab Mon Sep 17 00:00:00 2001 From: Jan Beulich Date: Mon, 25 Jun 2018 04:45:49 -0600 Subject: [PATCH] x86/Xen: further refine add_preferred_console() invocations As the sequence of invocations matters, add "tty" only after "hvc" when a VGA console is available (which is often the case for Dom0, but hardly ever for DomU).
