Usage:
vga="none"
With upstream qemu it was impossible to disable emulated vga,
even with -nographic qemu parameter setted with nographic xl
paramter.
Note:
Tested only with upstream qemu. With the qemu-trad. it probably
needs also the addition of -nographic qemu parameter.
Can someone test it with the traditional or should I do it?

Fix xl nographic parameter with upstream qemu using vga none
instead of -nographic qemu parameter not working anymore and
deprecated.

Shouldn't we be passing -vga none to QEMU instead of nothing at all?

Is not needed, there is already -nodefaults and -vga is also deprecated
and following the qemu docs:
http://xenbits.xen.org/gitweb/?p=qemu-upstream-unstable.git;a=blob;f=docs/qdev-device-use.txt
the new parameter for replace -vga=none is -nodefaults
the -nodefaults patch is already on git:
http://xenbits.xen.org/gitweb/?p=xen.git;a=commit;h=6ef823fdfa701b3659e4161520f43b5835338fb5
and also the new parameter for vgas:
http://xenbits.xen.org/gitweb/?p=xen.git;a=commit;h=74914a4b9daa7ce8bb65744f2715ed92b6f34e28
without this patch is impossible disabled emulated vga with hvm domUs
(problem found time ago trying nographic xl paramter), the succesive
patch fix also nographic parameter.

Ah right, thanks for the detailed explanation.
Please test the patch with QEMU traditional too. The upstream QEMU
changes are fine by me.
