## Description

Xen 4.5.x and earlier enables certain default backends when emulating a VGA
device for an x86 HVM guest qemu even when the configuration disables them,
which allows local guest users to obtain access to the VGA console by (1)
setting the DISPLAY environment variable, when compiled with SDL support,
or connecting to the VNC server on (2) ::1 or (3) 127.0.0.1, when not
compiled with SDL support.
