Descriptions

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.

Xen 4.5.x y anteriores capacita a ciertos backends por defecto cuando emula un dispositivo VGA para una gemu invitado de x86 HVM incluso cuando la configuración las descapacite, lo que permite a usuarios locales invitados obtener acceso a la consola VGA mediante (1) la configuración de la variable de entorno DISPLAY, cuando esté compilada con el soporte SDL, o la conexión al servidor VNC server en (2) ::1 o (3) 127.0.0.1, cuando no esté compilado con el soporte SDL.
