Subject: [Xen-devel] [PATCH v4 03/16] libxl: fix qemu-trad cmdline for no sdl/vnc case
Date: Wed, 15 Jan 2020 03:39:42 +0100 [thread overview]
Message-ID: <763f8aec657f880b29e495d4158db49c2afddbbe.1579055705.git-series.marmarek@invisiblethingslab.com> (raw)
In-Reply-To: <cover.f819645cd9f5cf7a6f692f9661cfb4e670a2cd08.1579055705.git-series.marmarek@invisiblethingslab.com>
When qemu is running in stubdomain, any attempt to initialize vnc/sdl
there will crash it (on failed attempt to load a keymap from a file). If
vfb is present, all those cases are skipped. But since
b053f0c4c9e533f3d97837cf897eb920b8355ed3 "libxl: do not start dom0 qemu
for stubdomain when not needed" it is possible to create a stubdomain
without vfb and contrary to the comment -vnc none do trigger VNC
initialization code (just skips exposing it externally).
Change the implicit SDL avoiding method to -nographics option, used when
none of SDL or VNC is enabled.
