[PATCH] tests/qtest: Don't run the dbus-display-test without CONFIG_VGA_PCI

[Thomas Huth]

When compiling with "configure --without-default-devices", the
dbus-display-test fails since it implicitly assumes that the
machine comes with the standard VGA card. Thus add a check to
meson.build to disable the test if the VGA card is not available.

Not necessarily VGA, but a graphic or VC console. I am not sure how to
guess from the binary or compilation settings. Maybe it would be
simpler to check at run-time if /org/qemu/Display1/Console_0 exists. I
can work on a patch.

Well, the test currently does not use any -device or -vga options, so it 
assumes that the default graphic card is around - which happens to be the 
VGA_PCI card for x86.

That sounds like a more robust solution indeed, so a patch would be very 
welcome!

  Thanks,
