The -sdl wasn't really removed it seems - although it did me peeking
into the rabbit hole for a make check failure...

Having "-sdl" in the args for qemuxml2argv-graphics-sdl.args and
qemuxml2argv-graphics-sdl-fullscreen.arg caused 'qemuargv2xmltest' to fail.
Running with debug on showed:
48) QEMU ARGV-2-XML graphics-sdl
... Got unexpected warning from qemuParseCommandLineString:
2015-11-09 21:52:58.744+0000: 7908: info : libvirt version: 1.2.22
2015-11-09 21:52:58.744+0000: 7908: warning : qemuParseCommandLine:13603

49) QEMU ARGV-2-XML graphics-sdl-fullscreen
... Got unexpected warning from qemuParseCommandLineString:
2015-11-09 21:52:58.744+0000: 7908: warning : qemuParseCommandLine:13603
: unknown QEMU argument 'cirrus', adding to the qemu namespace
^[[31m^[[1mFAILED^[[0m
So someone was stripping (or not stripping) an argument...
Since graphics-sdl.args has:
-parallel none \
+-sdl \
-vga std
and graphics-sdl-fullscreen has:
-full-screen \
+-sdl \
-vga cirrus
After a bit of debugging - qemuParseCommandLine has the following:
} else if (STRPREFIX(arg, "-hd") ||
STRPREFIX(arg, "-sd") ||
STRPREFIX(arg, "-fd") ||
STREQ(arg, "-cdrom")) {
WANT_VALUE();
If I add:
} else if (STREQ(arg, "-sdl")) {
/* Ignore */
Just before that, then things are happy again.
While looking for the cause I also noted the following:

later in this code there's a:
if (virQEMUCapsGet(qemuCaps, QEMU_CAPS_SDL))
virCommandAddArg(cmd, "-sdl");
The second caps check is probably unnecessary now.
